First there were the Egyptians, then the Chinese, then the Greeks and those pushy Romans. Now, it's time for the mythology of the COMPUTER! I am looking for stories. Heard any tales second- or third-hand that sound possibly true but that "happened to a friend of a friend" in different places at different times? Good God, man or woman, that's a computer myth! I'm also interested in stories that might have started in actual fact but that have become so popular that they keep popping up. For instance, did you hear about the zero-sum check? Someone gets a computerized bill from a credit card company saying they owe the company zero dollars and zero cents. They ignore it but keep getting bills and increasingly nasty computerized notes, so they finally write out a check for zero dollars and zero cents and send it in, and the computer never bothers them again. Or, there's the story about the guy who falls asleep in front of his terminal with an ELIZA program running and his boss logs on and thinks he's talking to him but is actually talking to the program, and gets pissed off. OR, there's the dilemma in which computers keep crashing because an operator wears a silk slip that gives off static electricity like nobody's business, OR the bank teller who embezzles millions from his bank by creating a file to collect the fractions of pennies that the bank rounds off from accounts. Some story categories are: 1. machines going physically berserk. 2. women/computers/sex/sexism and/or romance. 3. sabotage. 4. breaking security (no, I don't have classified clearance, goddammit!) 5. great hacks. 6. computer gods (such as Norbert Weiner, a genius in AI who lost his family when they moved to a new house and he forgot where it was). 7. tales of massive catastrophe due to seemingly mysterious means that turn out to be something strange, like magnetized pollen. Of course, there are more categories. Got a great tale you want to share? Reply to isusevm@pyr.gatech.edu. If you'd rather talk, leave your phone number and I'll try to give you a ring. -- -------------------------------------------------------------------- Karla Jennings This account is temporarily being used as a collection point for mail. isusevm@pyr.gatech.edu

It turned out that one of the users would come in, sit down at the console and put his papers and stuff on the top covering the cooling vents. When it crashed, he'd pick up his stuff and leave, removing the evidence. Service people didn't figure this one out until they decided to watch him work to see why it crashed. 2) We had an IBM cluster controller controlling some 3270 terminals. We paid $5000 for an upgrade that would allow more users to be connected to the controller. The IBM service rep came in and REMOVED a board, that was put there to deliberately slow things down. 3) (This one happened to me) A Northern Telecom 3270 terminal caught fire, with flames coming out of the top. I guess I was doing some hot stuff. I was not putting stuff on top of the terminal cooling slots. 4) Somebody working on an Airline Reservation System, trying to get maximum response out of the machine, was looking at a OS listing and found a delay loop that was executed by a timer interrupt every 100th of a second. Removing it brought the performance up, but they had to replace one of the chips in the machine that wasn't fast enough. I don't know if these classify, but it's the best I could come up with. -- Paul Tomblin, Second Officer, Golgafrinchan B Ark | o o Are we UUCP: nrcaer!cognos!geovision!pt ?? | v having Disclaimer: The opinions expressed here aren't | \_/ fun, yet? necessarily even mine! |

In a similar vein, the GE 415 and 425 CPUs were identical except that the 415 had an extra wire that slowed the clock down a bit. To upgrade to the 425, after paying your money, the wire was removed. Some users knew about this and one of them made up a realistic looking letter supposedly from GE saying something to the effect : "CAUTION. Do not remove the wire from pin 4AB to 7FL in the CPU enclosure. This wire is located approximately 7 inches up from the bottom of the backplane in bay 2 and should not be removed by using a GE 112-3 wire unwrapping tool, first not removing the wrapping from 4AB, then pulling the wire from under the other wiring to its bound end at 7FL, followed by not unwrapping the bound end from 7FL. Not removing this wire will result in the normal clockspeed which is 1.6 times slower than with the wire removed and will not cause corresponding increases in system throughput." Naturally most of these wires got removed. Another interesting but kludgy fix to a problem came from a user of an IBM 7044. The 7044 had a HALT instruction that stopped the CPU clock. The user was doing some realtime processing or something of the sort and didn't like the idea of the CPU ever being able to stop itself. He asked IBM how much it would cost to disable the instruction and they gave him some large quote which contained the implicit message "We don't want to do it and this price is set high enough to make you change your mind about the request." The user didn't want to pay the money so he fixed up a photodiode over the light on the console that was on when the CPU was running and hooked it up to a solenoid that would push the RUN button whenever the light went out. The cost was a couple of dollars. Jack Gjovaag Tek Labs

I heard one story about a guy that was using an Apple IIe at work a few years ago. He was ready to give up with computers because every disk he ever tried to use would lose all of the files on it. It turned out that he kept little reminder notes attached to the disk drive - with magnets.

Well, they stared and kneeded the watched without effect until lunch, when they palmed 'em and nuked 'em for a minute on high. After lunch the researchers were astounded!

This is a true story (honest!):
A friend was having a problem with a sticky keyboard for his Mac.
He was talking to another friend who off-handedly suggested putting
into the dishwasher to clean it up. So, my friend did just that!
Needless to say, the keyboard didn't function any too well after
that. :-)

Yet another true story:
I was at GE Consulting's Training and Education Center in Albany, NY taking
a course on the PC. Well, there were some inexperienced PC users there,
so we had to go through the "basics" for them (ie, the do's and don't's of
disk handling)
Well, according to the instructor, there had been one student who had driven
up from Bridgeport, CT (corporate offices are there). He had stayed at a
nearby motel overnight, leaving his briefcase in the trunk of the car. (Oh,
let me add that it was sub-zero weather at the time of this incident). In
the morning he arrived at T&E, opened up his briefcase, took out a floppy
disk, inserted into a drive... then *c-r-a-c-k*!!! It shattered into little
pieces.
Gee.. I hope it wasn't critical information on it, with no backup :-)

Heard a story about a company whose PC software was being blamed for
the consistent failure to read backup data off floppies. Unable to
determine the cause, they finally sent someone to sit beside the
system's user the entire work day. Nothing unusual was seen until
the very end of the business day when the user took the floppy out of
the drive and started to label it. A blank label was put on and the
disk inserted into the carriage of an electric typewriter...
The humor of the anecdote overrides any concerns for veracity.

(from mem) When I used to work at a Radio Shack store, we got a call one day from a man who was trying to load a program (Blackjack, I believe) off of tape into a TRS-80 Model I computer and run it. A friend of mine went to the phone and told him that after he loaded it, type "R U N" and press enter. He got a syntax error and after reading it back, it turned out that he had typed "Are You In?" and pressed enter. No Lie, I WAS THERE. Zap Savage "Go on, pull the other one!"

When I was a freshman in 1971, all mainframe jobs were submitted on cards. And there was a snack room with microwave oven just down the hall. Well, we were waiting for our jobs to run and were bored, so one of my friends had the idea - What does a microwave oven do to a card deck? We got a deck of blank cards and cooked them for a while. It is a simple physics problem to show that uniformly heating a sphere leads to MUCH higher temperatures at the center compared to the edge. Of course, the card deck *looked* perfectly normal, but inside it was charred, black and brittle. No, we never submitted such a deck. We took pity on the operators and the poor card reader... (And with dozens of drawers of card decks to chose from, it would have been easy to cover our tracks.) And then there are all the stories of "rewind and break tape" macros, (almost) all discovered accidentally. Or the Fortran print statement that did a line of underlines without advancing the paper, repeated that oh, 100 times, then did 100 form feeds. The operator was untangling that printer for some time... This school did have a very well-followed honor system, and it was considered extrememly bad form to affect anyone else adversely. -- A.

How about the young computer salesman giving some client a demonstration of the new electronic word-processor? He loads up a large document, and says: "watch this!". He hits a couple of keys, and converts every "i" in the document to an "a", making the text unreadable. "And it you can change it all back, just like this" he proclaims,subsequently converting all "a"s back to "i", including those that had been "a"s originally. Ofcource, it happened to a friend of a friend of mine.. :-) ----- Another one my father told me: My dad was an electronics engineer in Greece, for a company that imported various high-tech lab equipment. One of them (A HP spectrophotometer, I think) was controlled by a special built-in computer, running optional proprietary software. Each optional package was copy protected. To enforce that, installing the package could only be done by a tech-rep; after the installation, the disks were automatically erased, and the program was kept in battery-backed RAM. Anyway, at some point the computer lost all its programs. A call had to be made to Germany, for new disks to be send as a replacement. My dad could not find the reason for this, and he was really surprised when the client called again, with the same problem next week. Call Germany again, install the disks again, then next week guess what happened: The lab calls again. But there was a definite pattern: The lab always found the system down on a Wednesday morning. Obviously, whatever went wrong happened on Tuesday nights only.... After more than a month of downtime, someone realized that the cleaning lady came to the room every Tuesday night. Someone went to check her and found out that she carried a nine-year old kid with her. The kid had discovered the machine's on-off switch, with a few buttons next to it. When the machine was on, pressing those buttons made cute sounds(aka. audible warnings!) which are supposed to alert you to the fact that holding the button down for a few seconds would completely reset the machine. I guess the kid thought of it as an oversized musical instrument. The mom turned the machine off before she left, erasing error codes etc. No-one knows how much this story cost the lab in downtime..... ------- || | ||| | | || || ||| | || | ||||| || Michael S.

This tale is true, I was there. The DEC users group here occasionally has Q+A sessions with a representative of said company which sometimes become complaint and apology sessions. I remember one particular complaint from a Physics professor who claimed that his microVax was having problems with its tk50 tape drive and he had lost a fair quantity of data when the drive allegedly mangled a tape (magnetically, not physically). Some discussion ensued and the professor griped that he also didn't like the way that the screen display "flexed" every time they turned the equipment on next door. It turns out that the "equipment next door" is a largish Tokomak fusion reactor - the electromagnets in the thing have to be seen to be believed. (And this man is a physics professor - phew!) Tim.

My favorite story is about a satellite link that went haywire every Friday at 3:00 PM. The company that owned the link immediately blamed the software in their communications controllers. Systems analysts were dispatched on site, and try as they did, they couldn't find a software bug that could be responsible. Finally, by dumb luck they found it. A bunch of factory workers let off at 3:00 started their weekend with a parking lot beer party and through their empty cans in the satellite uplink. A shift of security guards fixed that. -- Dan Mercer Reply-To: mercer@ncrcce.StPaul.NCR.COM (Dan Mercer)

Several years back I was working at a HMO and we had a lot of 8080 micros using ADM3A dumb terminals. These terminals were so dumb that all they had were upper case character sets. Eventually, upper managment was talked into upgrading them to the ROM's with upper and lower case characters. Well, one day we received this big three foot square box from the terminal manufacturer. Everyone was puzzled as to what they could be sending us. The person with the order said he had asked for 30 lower case options. The ADM3A terminal has an upper and lower clamshell like case. When the box was opened we found they had sent us 30 lower halfs to the terminal case. -- ______________________________________________________________________________ || Frank Korzeniewski, Consulting Suite 137 || || Phone: (415) 799-1819 1564-A Fitzgerald Drive || || UUCP: uunet!frksyv!frk Pinole, CA 94564 ||

I have two stories to relate. Both have to do with IBM machines (the large veriaty): 1) Back when core memory was in use one could "listen" to the memory with a transistor radio. A game amung system programmers was to access memory in such a manner as to produce recognizeble tunes on the radio. 2) Printers produce a buzzing with varying frequency depending on the text being printed (this is because of the rate at which the hammers strike the slugs in the print chain). The same system programmers would also compete to see who could print a job that played specific (and known) tunes. One further story that comes to mind. It is said that specific models of IBM mainframes had a bug whereby "branching backwards over a page boundry to a paged out page would leave the supervisor bit turned on in the PSW in the stored PSW". I never was able to verify this but it makes some sort of sense when you look at the hardware that IBM uses. - Yossie -- Yossie Silverman What did the Caspian sea? National Semiconductor Ltd.

Our company bought a text processing package and a salesman came to us to
install it. He had some difficulties in first time to install it, so he
decided to delete all his files and start over. But alas, instead of
typing DELETE [...]*.*.* (Yes, it's in VAX/VBMS), he typed
DELETE/NOLOG [*...]*.*.*
Few moments later i noticed that i had much more disk quota left than i
should have and noticed that all my files with DELETE privilege for same
user group had gone. And for everybody else too.
It was lucky that the salesman was not using system account.

While a student at UCSD in the middle 60's I had the opportunity to
work many late nights in the computer punch card room on my physical
chemistry lab calculations. One late night when the computer operator
was obviously bored, he invited me into the sanctum sanctorum - the
computer room. The computer was a CDC 3600 and had a curving CONSOLE
about 8 feet long with several hundred lights and switches (in those
days, there was no such thing as terminal input). On the far wall was
a bank of a dozen 1/2" tape drives with vacuum column tape tension
control. He loaded up a deck into the card reader (the only command
input device) and started it. For the next 1/2 hour the computer
PLAYED the Stars and Stripes Forever and assorted Sousa marches,
using the tones on the CONSOLE (every light had its own tone) for
the high low notes and the tape drives for the low notes. At the
same time, all the lights on the CONSOLE were blinking on and off.
Since I am now a full-time programmer, I finally appreciate the work
it must have taken a system level programmer to do that. Talk about
primitive audio devices!

Well, the DECUS part is right, the rest of the story sounds right, so I guess this was me....but Larry, you left out WHY we made the RP's wander! Seems I was a young hotshot programmer-type and was working in the corporate research unit of a big company (lets see, it makes LOTS of bandaids). Well, it was the first time I ever used a machine with a disk drive in a room that I could find (much less have permission to enter). Never having had a computer with version numbers before (this was RSX-11M 3.0 - dating myself huh?) I never purged my directory. Also given that I was hacking an immense Data-entry and retrieval system in Fortran-IV (more dating (-: ), TKB would do intense things to the drive, which was fragmented beyond belief. This tended to upset the system manager, one Mark Googleman, no end, since he'd have to move the beast back into position. Since two hackers on one machine naturally tend to competition (could you crack into the machine, get priv'ed, and log the other off BEFORE they noticed and logged you off?) and I was embarassed when confronted with the proof that this was my fault, I naturally bluffed my way out explaining that I was doing on purpose. Well, one thing led to another, and it became a ritual to leave taped papers to the floor with one's name on it in the computer room.

Time for some DEC stories.
A lot of the PDP11s had optional floating point hardware. The assembler
program had an option flag so that it could either assemble floating
point instructions or assemble calls to a library of software routines
simulating the floating point hardware. Well, once upon a time they
released a set of diagnostics for the floating point hardware that had
been accidentally assembled using the software simulation flag, so they
didn't exercise the hardware at all...
We had a system start crashing frequently, trashing the system disk in
the process. After a lot of very painful examination by hand of disk
contents we concluded that it was occasionally missing a word
transfer, or doing an extra one, depending on the direction of transfer.
This we traced to a bad Unibus receiver chip that was allowing a glitch
to get through as a legitimate pulse. The annoying thing was that the
disk diagnostic program never detected the problem, because it wrote
and read back a block of identical words, and didn't clear the read
buffer between reads. When every word looks like every other you don't
notice the missing or extra ones.
Another G.E. story: nothing wrong here, just an interesting consideration.
In MULTICS the customers wanted the calendar time kept in something like
microseconds since midnight, January 1, 1901. We had a whole rack of
equipment just for this clock, which used something like a 72-bit
register. Some of the most significant bits of the clock wouldn't
change for years after it was built; so we had to have logic that
would copy the value to another register, flip all the bits, verify
that they flipped, then flip them all back and verify that they all
flipped back.
I had occasion to look at the date routines in an early version of the
operating system for the Burroughs 6500. Not only did it take care of
leap years every four years; it correctly handled the exceptions for
centuries and millenia. If you're going to write software that is
correct, you might as well write it to be correct for the next few
thousand years. I guess you don't worry about the extra computation if
it's only executed once a day.

There was an article in the Wall Street Journal this past summer that told
of executives who were finally learning how to use/misuse their office
computers. Two stories that I found particularly funny follow:
1. One executive was reading directions on how to boot his machine with
a floppy disk. The directions said to remove the disk from it's
protective sleeve and place it in the disk drive. He was having trouble,
and when the serviceman showed up, he found that the executive had
removed the actual disk from the square plastic that it comes in. No
wonder the machine wouldn't boot!
2. Another executive read that he should hit the Enter key, "the one with
the elbow printed on it." He was seen later that day attempting to
hit the enter key with his elbow.

In 1972, I was assigned the task of writing an interactive user interface for a statistical analysis program written in FORTRAN IV. I was told that the users were "MBA types; not very quantitative and with little background in statistics." ( I hope this is no longer true of MBA's.) Anyway, writing such an interface in FORTRAN IV was no picnic, but I tried to make it very friendly. Plain English questions, examples of correct answers, range checks to determine validity of responses, helpful error messages. One of the first users to test the program said that it kept bombing out on question 3. "Enter number of thingamabobs (Valid responses 1 to 5):". I asked what her response had been and she said "Five". Puzzled, I asked if I could watch her run the program. This is what I saw: ...(Valid responses 1 to 5): FIVE That's when I realized what nonquantitative really meant. Even though FORTRAN IV had no character string handling capability (You had to declare your characters as INTEGER or REAL), I had to write a routine to read all keyboard input as characters, convert to numbers, and add a friendly message to explain what a number was.

When Grinnell College upgraded from a PDP 11/45 to an 11/70, the DEC field engineer finished the installation and booted the 11/70. It started up, and 15 seconds later, it promptly died. He tried it again, and it failed again. He called up his superior, who thought about it for a few moments, asked him if he had removed the loopback plugs on all the serial interface boards. It seems that RSTS/E sends out a message informing the users that the system is on its way up, and when the message was sent, the loopback plug turned it into a user input, to which the system sent a message 'input ignored.', which also became user input ..., and the system died because it ran out of free buffers.

A friend of mine used to work for Northern Telecom, and said this story circulated there: A team of installers was installing a DMS-10 digital telephone switch somewhere in Tenessee. They had it set up and had been testing it all day; everything seemed to work okay, so they left early in the evening to go barhopping and rabble-rousing, as NT installers are said to be wont to do. Next morning they came in only to find that the switch had failed during the night, and a couple of circuit boards were fried to boot. They replaced the boards, tested it all day, and left again that evening. Next morning, same result. This went on for a couple of days, and finally one of the installers bunked down next to the DMS-10. Along about midnight, in came the cleaning lady with a feather duster, and proceeded to dust everythibg in the room, including the exposed circuit boards. UNRELATED STORY: When I was an undergrad at UNC, I spent a little time in the graduate department's graphics lab. When one of the grads was showing us the hardware, he pointed out a large rubber mallet sitting beside one of the cabinets. He said that the connection between the chips' prongs and their sockets sometimes became poor, and often when the system acted up the cure was to bang on the cabinet with the mallet to reseat the chips. He also said anytime they had a photo of the lab taken, they made sure the mallet was visible in the picture, and sent a copy to DEC, who apparently knew exactly what the mallet was for.

Better yet, both spacecraft were still going strong in 1980 and most of the crew were long gone to other projects. Everyone had to be called back for another download to Mars. It pays to include leap year into your code. From personal experience: I remember a Lunar-Lander game written in PDP-11 TECO that used VT100 cursor keys. The entire program looked like your terminal was at the wrong baud rate (standard TECO programming form). It ran without change on the old PDP-10 still surviving at college and later on the brand-new VAX as well as 3 different O/S versions of PDP-11 without change. From rumors of ancient DEC history: The system programmer group writing TOPS-10 used to love fancy TECO programs and had a weekly contest for them. One guru working on ForTran compilers would read them carefully but never enter one. They thought he was just concentrating on compilers. Then one week he submitted a macro that did ForTran compilation, complete with optimization. The TECO program took days to run, but it worked. Apparently he had written a PDP-10 instruction set emulator in TECO and feed the compiler to it! dougf@wega.caltech.edu Douglas J Freyburger Caltech 206-49 Pasadena, CA 91125 (818)356-2913

Back in the early days, I was using an ADM-3 from a friend's house (hi
Greg Jorgenson!) with an old acoustical-coupled modem. The modem was
attached used on the house phone... a party line (!). We were
accustomed to getting bumped with funny little noise characters when
the party-liners would try to pickup the phone for a call, but
otherwise tied up the line for the usual hours-on-end we hackers are
known for.
One day, we picked up the phone to make a call, and found that the
party-liners were on it (two female voices). Since we had nothing
better to do, we decided to listen in. The conversation went
something like:
Voice 1: Did you just hear that?
Voice 2: Yeah, it was a click. Must be our party line.
Voice 1: A party line? Does that mean they are listening to us?
Voice 2: I don't think they can. All I can hear when they are talking
is some beeps.
We scrambled to hang up the phone to cover our instant hysterical
laughter. Little did they know... :-)

Heard recently from an IBM field service manager: A huge travel agency in Florida (a major booker of Caribbean cruises for blue-haired retired ladies) recently bought an IBM 3090 to handle the reservation database. When the deal was consummated, the proud new owner asked IBM to install it in a big glass room right behind the receptionist's area so all the customers could see the flashing lights and spinning tape reels as they walked in -- a testimony to the modernity of the agency. Good idea, except there are no blinking lights on a 3090. So the service manager offered to build some. They hired a theatrical designer to come up with a suitably futuristic "set", got curved glass walls to minimize reflections, and installed the mainframe behind the "real-looking" facade. The customer declared that it was exactly what he had in mind, regardless of what the actual computer looks like. Moral: the customer is always right. -- Vance Bass The opinions expressed here are strictly IBM M&SG my own, and do not necessarily Knoxville, TN represent IBM's views on the subject.

Yet another true IBM story:
My girlfriend's father is a service tech for IBM. He had one computer
that would periodically lock up for no apparent reason. He tried
replacing all sorts of boards, drives, and other hardware to no avail.
Finally, he called in the specialists.
The specialists arrived with many special tools, and in one case a
very special tool. In an old style case, in a custom-molded velour
covered interior, sat the Vibra-matic - a rubber mallet. They had
brought this as a joke, but....
It turned out that the power supply wasn't completely welded to the
ground, and the vibration of the machine caused intermittent power
failures of extremely short duration. This was fixed, and tested with
the specialists banging on the chassis with the Vibra-matic while my
girlfriend's father stuck his head inside to look for vibration.
Luckily the owners of the machine never saw them.

One of the design engineers at G.E. kept an electric vibrator in his desk. I think it was originally an engraver, not a massager or sexual vibrator. Anyway, when we seemed to have intermittent problems in a machine he would plug in the vibrator and touch it to each circuit board in the suspect area while running a diagnostic program. At that time G.E. had a small enough number of machines in the field such that when a customer's machine was in bad trouble and the regular field engineers couldn't fix it the company would pull together a small group of engineers and programmers who had participated in the design of the hardware and software and send them to camp out at the site until the problem was solved. So that's where the vibrator probably found the most use. haynes@ucscc.ucsc.edu haynes@ucscc.bitnet ..ucbvax!ucscc!haynes "Any clod can have the facts, but having opinions is an Art."

Sounds like a bug I just fixed in the syslogd we use here at Athena. Our syslogd is modified to allow syslog message to be sent out to users over the network using the zephyr message delivery system. One of the requirements of all pieces of software using zephyr is that they call the routine ZInitialize() before using any zephyr functions. Well, one day I decided that I wanted to receive *all* syslog messages on my workstation, so I placed "*.debug jik" in my syslog.conf file. Instead of receiving all messages, the next time I rebooted the workstation I stopped receiving any messages at all! It turns out that the person who put the zephyr code into the syslogd sources placed it *after* the syslogd init call. The init call attempts to log a startup message on level syslog.warning. Since *.debug gets syslog.warning messages, it attempted to send me the startup message over zephyr. Well, ZInitialize() hadn't been run yet, so this generated an error, which syslogd promptly attempted to log to syslog.error, which therefore attempted to send a notice out to me, which generated an error, which syslogd promptly attmpted.... you get the idea. It eventually died a cruel, horrible death and didn't so much as leave a core file. The fix was nothing more than moving two lines of code eight lines down in the sources. Of course, in the infinite wisdom of the release engineering team here, that fix has *still* not been installed in the standard release, although it's been several months since I submitted it :-) Jonathan Kamens USnail: MIT Project Athena 410 Memorial Drive, No. 223F jik@Athena.MIT.EDU Cambridge, MA 02139-4318 Office: 617-253-4261 Home: 617-225-8218

Most of the people he was dealing with started out being completely computer- illiterate. One such gentleman had a database set up for him by my friend. He was given explicit instructions on how to start up every morning and shut down at night. After a week, my friend received a frantic call from his client who said that the computer "couldn't find any data". My friend (who did back up the system previously) told the gentleman what to do, relay the results to him over the phone. Sounded like the data disk was erased, so my friend told him how to copy from the backed-up diskette. Everything went fine, the gentleman thanked him and went about his computing merry way. Next week, the same scenario occurred. And the following week. On the fourth week, my friend (slightly perturbed by now) instructed the client to shut down the system so he could observe the procedure first-hand. My friend went down to his client's place of business and sat down with him. He then asked his client to "go ahead and start 'er up". The gentleman booted the PC, started the software program, and was ready to insert the data disk. He turned around and removed the diskette from his white-board, the diskette being held up with a small magnet. After peeling himself off the wall, my friend went on to instruct his client on the theory of magnetic media (and charged him a sh*tload of money for being so stupid! only kidding :^). My other story again has to do with the perils of the 5 1/4" floppy disk. My 2 college roommates and I were playing some computer games one Friday night (real exciting bunch, huh?) when we decided to make it into a drinking game (typical college attitude). Well, one of my buddies was into slow-gin (sp?). We got a little too happy |^) and spilled one of these drinks all over the diskette (it was out of the drive at the time). We didn't notice this until the next morning (or was it afternoon?). The diskette with our FAVORITE GAME was destroyed! (or so we thought) Just then, my other roommate had the bright notion (actually, he said he heard of this somewhere before) of salvaging the diskette by removing the magnetic media from the jacket (all very sticky at that point) and gently rinsing it under luke-warmwater (from Star Wars, remember him? sorry). We replaced the cleansed and dried floppy media into a clean jacket, copied it onto a good blank disk, and had our game running in no time! From that point on, all floppies toted the phrase, "Dishwasher safe, and just look at that shine!" Ron P.S. I guess I wasn't so brief after all. Sorry.

Back in my undergrad years, a fellow student had access to the departmental PDP-8. He also had access to the academic centre's machine room, and somehow acquired the PDP-10 sign from that system. The PDP-10 sign was hung proudly on the PDP-8, particularly when a tour was being given. When asked about the sign, his reply was: "Octal".
brent@uwovax.uwo.ca (Brent Sterner) (02/10/89)
A caper which preceeded my employment at this site (and that is a *long* time ago :-) involved on of the first PDP-10 systems ever shipped. (I have trouble remembering if it was serial number 8 or 10, octal or decimal.) The time frame was 1967 or so... Those early PDP-10 systems required assembly and linking of the OS, and deliberate software switch setting to enable certain "features". One release of the OS had a new feature, called "swapping". Hackers have been around a long time. There was a rather strong desire to test this new feature. Problem was, there was no disk available to try it out on. Or was there... Next to the PDP-10 sat an IBM 7040 system. Like the PDP-10 system, it used a 36 bit word. And you guessed it. The 7040 was programmed to read and write the data channel assigned to swapping. And it apparently worked. I don't know the authors of this effort. Names of people who might know more include John McHardy, Dave (?) Freedman (?), and/ or Dave Ellwood. I'd very much like to get this story straight, so if anyone knows the whereabouts and can correct the story, it would be appreciated. b.

Back in the good ol' days of card readers, a game we discussed was how to obtain passwords. Jobs were submitted by setting your deck of cards on a counter. An operator would grab all the jobs on the counter, run them through the reader, and return them with their output later. We're talking CDC hardware here, so various combinations of 6-7-8-9 or 7-8-9 punches indicated End of Job, or End of Record. Well, there was a magic combination (6-8-9?) that was interpreted as "read binary, and ignore other control punches except the magic combination." So, the devious programmer submits two jobs, the first has a program to read binary data, followed by a 6-8-9 and (for the operators consumption only) a 6-7-8-9. The second job just has a 6-8-9 to switch the system out of binary mode. The two jobs are placed on the counter is such a way that the first job will be the first on through the card reader and the second job will be the last one through the card reader, with other students jobs inbetween. Viola', you've got a whole list of accounts and passwords. Of course, the operator might become suspicious when 10 jobs go in and only 1 comes out. Or, he might scramble the order of the jobs left on the counter defeating the plan. I'm not sure anybody actually did this, but it strikes me as an easy way to breach security. ----------------- I'd rather die on K2 than I-5 ------------------------ Curt Charles | "Let our swords run red with the blood of curtc@pogo.GPID.TEK.COM | infidels..." -- Sean Connery

Peterson and Silberschatz (_Operating_System_Concepts_, Addison- Wesley, 2nd edition, p.121) point out the importance of good scheduling algorithms when one is designing an operating system: "Rumor has it that when they closed down the 7094 at MIT in 1973, they found a low-priority job that had been submitted in 1967 and had not yet been run."

Another subclass of computer folklore is the occasional barbed comment
that one can find when reading through source code. Operating-system
programmers seem particularly prone to witty, shamefaced, or other
slightly-off-center comments in their code.
Some examples come to mind (some of the details may be incorrect; it's
been a long time since I read any of this code):
1) DEC RSX-11M (???) operating system. System fault handler module. If
a bus-check fault occurs (indicating possible hardware problems with
some device on the bus), the O/S traps to a fault-handler routine
that tries to identify the offending hardware and reset it. If,
while attempting to recover from a bus-check fault, a second such
fault occurs, the system traps again... this time to a routine which
simply masks off all processor interrupts and hangs in a tight loop.
It's necessary to manually reset the machine to unhang it.
The comment on the loop reads "The death of God left the angels in a
strange position."
2) There are a couple of comments in the output-symbiont (print spooler)
code in the old Xerox CP-V operating system. At the top of a long
block of convoluted and otherwise undocumented code, there appears a
taunting
"See if you can figure out what I'm doing here."
Somewhat further on, there's a really dubious code-construct (I don't
recall just what was being done), adorned with the comment
"I'm ashamed of this"
3) In the synchronous-terminal (BISYNC) module in the CP-6 operating
system's communications software, there's a routine that construct
synchronous data blocks (the ones that start out with the characters
"syn, syn, dle", and so forth). The code comment reads
"With a SYNC SYNC here...
and a SYNC SYNC there..."
The module is labeled "EIE_IO".
4) A related module, which was responsible for driving the Unit Record
Peripheral printer, was labelled "Y@URP".

As I said in my original posting, this was early 1970's; most input was still on punch cards. The whole idea of "users" other than programmers was a novel one. My program was actually pretty advanced for its time. In order to even make a syntax check, I had to write a number of string-handling functions myself. The syntax checking and character-to-numeric conversions also noticeably slowed down operation of the program. It could be argued that all in all it was better to let the thing bomb.

-------------------- I once worked at a company that released a version of Unix on a series of 7 floppies for installation on micros. These micros tended to be sold into doctor's and lawyer's offices where there were never any computer literate folk (and the vendors were always scarce when the end user's needed them). Hence we had many amusing phone calls on our 800 line placed by secretaries trying to load Unix. From: merle@felix.UUCP (Linda Merle) One afternoon the following awaited us on our return to lunch: "I'm following your instructions exactly, and I am still having a problem. I have placed floppies 1 through 6 into the floppy drive, but I can't stuff floppy 7 in no matter how hard I try!" Our directions said "Insert next floppy". We forgot to say "Remove floppy and insert the next". We spent the rest of the afternoon seeing how many floppies we could stuff into a floppy. linda -- ====================================================================== "If men are God's gift to women....

In 1968, while attending a large, midwestern University, I worked in the Department for Administrative Research. While providing design and programming assistance to the Alumni Records department, we ran into an interesting problem. The Alumni Records office desired to embed all kinds of information into the key value used to identify each of the school's alumni. This led to a very long, unwieldy key value. When mailing labels were printed, both the key value and a special code used by the mailing machines was required on the top line of the label. We ran out of space on the label. Not to worry! This fancy computer (a "brand new" IBM 360/50 running OS/PCP) could transform a numeric key value into an alphanumeric value by converting the alumni-record key from the too long base-10 number to a shorter base-36 number. Just use all of the letters and digits! Just as we sat back to congratulate ourselves on serving the user's needs with the clever application of technology, we got a call from the mailing house ... "Our delivery man just returned from the Post Office. They won't take your mailing. It looks like somebody tampered with your list. You better get down here right away!" There, on top of one of the trays of mail was a label with the converted alumni record identifier. It read something like ... ------------------------------- | 123FUCK69A4 MM 43210** | | MISS INGRID BEASLEY EDU. 29 | | ... | The mailing was instructing Miss Beasley to mark all further correspondence to the office of Alumni Records with her "new computer identifier code" shown on the label. Needless to say, the Office of Alumni Records failed to see the humor in it all. We thought that at her age, Miss Beasley (Edu. 29) might actually take the "computer's mistake" as a complement! Thereafter, we were instructed to add the "DIRTY-WORD-ROUTINE" which performed a table lookup of every word which a committee of about a dozen of the raunchiest people in the department could come up with. But what about short phrases? And how about maintenance of the table? Whose budget does this come out of? A student programmer, invited to a meeting to "see design in the real world" made an unwanted suggestion. Just convert to base-31 and don't use vowels. It worked. The next year, they changed the alumni records identifier again. I graduated. ------------------------------------------------------------------------------- David P.

Reminds me of the Univac 1100 series machine i used in grad school. Accounts were tight (student accounts always seem to be tight.) so getting borrowed accounts was a prime activity (it was considered illegal, but when you could blow your entire student computing account in a single run, what else could you do?). I discovered that when you asked for memory (or was it disk, or both?) what you got was not zeroed out. This meant that you could just keep asking for, then freeing memory and looking through it for the spots where people had entered their accounting information. Since every job started with a card that looked something like "@run xxx,username,passwd" (or something similar), it was easy enough just to run through memory looking for strings that looked like "@run", then save them and eventually print them out. By the time i figured this out though, i was a TA with essentially unlimited accounts. I did try it for amusement sake and in a fifteen minute run managed to collect somewhere in the neighborhood of a hundred different run cards. jeff putnam -- "You never learn anything... jefu@pawl.rpi.edu -- ...

They were using a UNIX system. The other guys used a security hole in 'Mail' to obtain privileged status. They altered rogue a bit to check if this person was playing the game, and to make the game much easier if it was him. The next time the poor guy played it, he won.

Way back in the stone-age of microprocessors I worked for a small company which made a TI9900 based machine for dentist offices. It included an old Diablo 10Mb disk drive. This was a 5Mb fixed, 5 Mb removeable type drive. These were the unsealed non-winchester type of course so you had a filter inside the drive to keep the disk area clean. (You know, the kind you put in expensive computer room). I was involved in fixing many of the disk drives that came back after suffering a dreaded head crash. I remember distinctly getting one disk drive back. We opened the drive up and removed the fixed disk since it had crashed. The platter had a distinct faded look, the usual dark brown had turned into a very light brown. The drive was filthy. Due to the strange shape of the drive, we asked the field service guy just where the drive had been. He explained that the doctor who owned the office had put the entire system except the terminal in was described to me as "the green-house". Looking back I suspect it was probably something akin to a solarium! He probably didn't like the noise the system made (ahh for the good old days when disk drives effectively simulated jet aircraft on takeoff) and put the system in the nearest place where nobody would be bothered. Sadly, I suspect that the company's demise some years later was due largely to the fact that the hardware required careful preventative maintenance and was unsuited to the turn it on and forget about it mentality of dentist's assistants and receptionists. Therein points I suspect to a major element in the ultimate success of PC's -- winchester disks. Turn it on and forget it!

I used to work at a Honeywell installation, where we had a super-genius
of a systems engineer, affectionately known as "Gentle Ben". This man
could read system dump the way most people would read the funny papers
(or the net? :-) He was the core of systems intelligence.
But as super-genius people are sometimes labelled "eccentric", Gentle Ben
was not an exception:
Smoking in the computer room was verboten, and he knew it. But he would
light up right at the operator's console, take a few drags, then suddenly
remember something and dash off, stuffing his *lit* cigarette into his
coat pocket... then wonder where the burning smell was coming from.
Drinking was also a no-no in the computer room, but Ben would stop by the
coffee machine on his way into the computer room and walk in with his cup
in one hand, his cigarette in the other. On several occasions he was
observed to place his cigarette *into* the coffee cup (still with coffee
in it) and a few minutes later, while engrossed in problem solving, take
a sip of the coffee... cigarette and all.. and not even notice!!!

Well, there are two stories that the people here at work keep repeating
(i's hard for a week to pass by without you hearing at least one of
them), so I thought I may as well torture you. Both stories are told as
"It actually happened to <some guy who no longer works here, the name
varies with the moon phase> with a customer (who nobody seems to
remember)".
The said Honorable Customer X called to say that he couldn't read the
data he wrote to floppy disk. He could write his files OK, but when he
read them, he either had read errors or trash (this part of the story
also varies with the season). He tried with various diskettes, alway
with the same result. This was told through the phone, and the Guy That
No Longer Works Here said we would probably be able to diagnose the
problem if the customer sent us a copy of the floppy. Two days later, he
received an envelope from the customer. It contained two photocopies of
the disk (one of the front and another of the back, since it was a
double-sided disk).
The other story says that a customer wanted something fixed for a
particular hardware setup for which we had no docs. The problem shouldn't
be difficult to solve, but we needed the docs and the customer was
really in a hurry. The person in charge of the thing asked the customer
if he would be willing to FAX us a certain part of the manuals. After a
moment's thought, he answered "OK, but only if you promise to FAX it
back!"
I'm really sorry

Hmmmm, been reading this thread for a while now and thought I'd
contribute to the massacre (pronounced mas-uh-crE, of course ;-)
I'll refrain (I hope) from duplicating any of the stories that have
already been related here:
A disgruntled employee at NavOCEANO (Naval Ocean Office, I believe)
across the street from me when I worked at NORDA (Naval Ocean R&D
Activity) decided to get even with the locals. There was a large
Univac installation there, and some ultra-high-speed card readers.
He hollowed out an entire box of punch cards (about 2.5 feet of cards,
for all you youngsters) and filled them with old old old bananas.
He then submitted this deck as a job. The operators were used to
multi-box jobs, so they usually just picked up the entire box of
cards and dumped them in the high-speed readers. It took over 3
weeks of maintenance before the reader was working reliably again,
and the control room reeked of banana for weeks afterwards...
When crucial data on tape was lost at my university, the gurus
in the computer room would retrieve as much data as possible, then
fill in the gaps by soaking the tapes in a solution that made the
individual bits show up as 1 or 0 (dark or light) under a magnifier;
they'd then hand-assemble the missing sections from the visual inspection.
I once spent an entire night (over 12 hours) trying to get my
compiler (working up to that point) to work again so I could work
on it some more for my compilers course. At the end, I had reduced
the problem down to a program (C code) that basically declared an
integer 'i', said "i=5", then printed 'i'. The program printed a
floating-point number... I was so angry I got the idiot who had been
mucking around with the C compiler from Bell Labs in the lab at
7am in Sunday morning to fix the damned thing.
Our aged PDP-10 finally died one weekend when we had an unusually
hot Sunday (there was no operator support on Sundays until 6pm)
and it turned out the fall leaves had never been cleared from the
AC vents by the university physical plant. The temperature got
over 100 degrees F in the computer room, and the old CPU on the
10 wouldn't even whimper afterwards.
It's amazing how many of us remember the "Good Ole Days" --
didn't you hate patching paper tape? Yeecchhh.

One day about 3 years back (when I was still in Mass.), a problem was reported with one of the AOS/VS system programs, which is fairly routine. The person in devlopment (which for that product was in Mass.) asked the customer support person (which is located in Atlanta) for a copy of the tape that demonstrated the problem. Evidently, the customer support person was still learning the ropes, because he/she put the tape on an office copier, and sent up a photocopy of the tape (rather than a magnetic copy). We all got a laugh out of it. To make things even better, the OS person was able to tell from the paper label on the tape, that not enough information was supplied, and that we would have to ask the customer for the requisite info. -- Michael Meissner, Data General.

One of my firstjobs (in college) was to interface a PDP-8 to a spectrometer.. except that the PDP didn't work and there was no service contract, etc. Turning on the system revealed a strange look to the front panel lights, which meant a blown fuse, which I changed and it blew again. I pulled out the drawer with the bus & boards and noticed a funny cloud above them which turned out to be some sort of fruit flies. (that should have warned me off :-)) Pulling the boards and shaking the tray with the bus upside down got out lots of dust,small pieces of wire,insulation and a few dead roaches. It worked after the cleanout........ Soon the application was written and the machine was interfaced, and the setup was getting lots of use from people doing their experiments and storing data. Every once in a while though, the entire sytem would freeze: the lights would indicate the last instruction/address and none of the front panel switchs would work. Powering it down and up would sometimes work, but not always. It always happened when the computer accessed the clock with a particular instruction. DEC,usually helpful, said "run the diagnostic" but the diagnostic froze at that instruction intermittantly also thus revealing no new information. The clock was sent out for repair; they could not figure out what was wrong except "darndess thing; same thing happens here too!". A different clock board also did the same thing... I found that shaking the entire bus would always get the thing working. It was a lot of fun when they "call in the computer expert"; I pull out the drawer, and while they expect some sophisticated fix, I give it a good hard shake, and gently slide it in and start it up. This fix would always work. After one time, the computer started to blow boards. It seems that someone saw me shaking the machine to fix, and decided to do it on his own, except he didnt power down first....(He stopped using the system after he was caught plugging the BNC from the photo tube power supply (a kilovolt or two) into the PDP's counter input.(it wasnt on at the time). (I finally discovered that the problem with the closk was powersupply: the traces were thin and drew enough current so that chips on top of the board were getting 4.6 volts: (minimum needed 4.75 TTL) Tweaking the power supply up a little to ~5.1 V solved the problem and it's been running fine for many years now.

what happened when they logged out previously.

K/I would log you out after querying you about what to do with
each of your files. K/F would happily log you out fast and keep
all your files. K/D would happily log you out and delete all your

Student accounts were not permitted to use the card punch, and were strictly limited on the number of pages per job. However, some wise guy discovered that the limits were applied AFTER each buffer was output. So, by declaring a VERY LARGE buffer, huge amounts of paper and/or cards could be produced. [ most of us used this to obtain cards, as this was a card-intensive system devoid of interactive terminals, and permanent disk space was not available to students. ] Tom Roberts att!ihnet!tjr

My task was to add a interface to an existing FORTRAN program so that it could be run by non-computer professionals on paleolithic terminals. If I remember correctly, we had two types: The old noisy teletype things that printed on what looked like a roll of bad paper towels, and the portable TI terminals that printed on heat-sensitive paper and had a telephone coupler. There were no screens then. I worked for a large management consulting firm. The program I was modifying was used by local offices throughout the U.S. People used to fill out a keypunch form and mail it to the New York office, where we would keypunch it, run the program and mail back the output. My user interface allowed them to dial the New York number of a time-sharing vendor (another idea in its infancy then), log into our account, answer the questions posed by the user interface, and get the results typed out immediately on their paper towel or whatever. This was considered truly revolutionary and impressed the clients no end. This is beside the point, but the time-sharing vendor used to print log-on messages; at least twice a week they would have a message that began:"Attention London users:". I was convinced that these were phony messages to impress on their other users that they had a London office.

In the early 70's I took care of a PDP-15 for a department at the university. It was an interesting machine: half a PDP-10 (18-bit words), faster than most early PDP-11's, but the hardware and instruction set had a strong PDP-8 influence. It even had two different buses, one of which you could hang PDP-8 peripherals on. About 750 of them were sold. The machine was fairly reliable (except for smoking power transistors on the DECtape drives every month), but at one point the main power supply started failing intermittently. Since we weren't on service contract, it was going to take a while for DEC to come out and fix the machine. So they gave us a procedure to follow so we could limp along in the meantime. The fix? Go to the back of the cabinet, second door from the right. Locate an imaginary spot about 18 inches from the floor. Now kick, but not hard enough to dent the sheet metal. This would allow the system to run for another 15 to 30 minutes before it crashed again. Turns out there was a mercury filled relay in the power supply. Kicking the cabinet make things vibrate enough to make the power supply turn on again for a while. We were glad when DEC arrived, although some people didn't get as much satisfaction running their programs after the real fix. Now you know why I prefer to keep my PC on the floor. ;-) usenet: uunet!littlei!intelhf!ihf1!bobd Bob Dietrich or tektronix!ogccse!omepd!ihf1!bobd Intel Corp., Hillsboro, Oregon or tektronix!psu-cs!omepd!ihf1!bobd (503) 696-2092

I am reminded of a vendor of mine at a company running Regulus (a real time Unix that used a variant file system. Instead of inode lists and lists of blocks for data (or bit maps, for that matter), it used a single free list for all blocks, inode and otherwise.). One dreary day this fella reported that he'd gotten an fsck error that morning in block 4 of his file system. Fsck asked him if he wanted it "fixed". He said say, so it did. It placed everything past the superblock plus one into the free space list. "Bummer", said I, "It's restore-time! You shoulda said 'no' and we could have tried to fix the damage with our ever-handy fsdb!". But alas, he had been coding for a week and neglected to make a backup. He called back a week later, having spent the entire week reassembling his file system 512 by 512 block by using fsdb to relink the un-zero'ed blocks in the free space list. Every 20 or so the block had been re-used to contain the free space list itself; these he lost, but for the most part, he did it.

Many moons ago (1982), I was on contract as a P/A to one of those credit card companies that shall remain nameless. I was attached to the project that was completely rewriting the billing process. The approved implementation included a massive number of database tables that the Credit Department would maintain to control thier billing cycles, appearance of the statement for different types of customers, interest charge calculation, and so on, ad nauseam. Well, as the project trundled on toward completion, the end user became aware of the manpower effort that would be required to initialize all of these tables. (In retrospect, their reaction was really quite excessive.) Our illustrious Project Manager said at the time, "No problem. We'll just promote the TestBed environment." I'm sure that you can imagine our reaction, as the mischevious minds of programmers tend to generate humourous testing environments. Sure enough, despite all of the programmers and testers objections, the TestBed environment was promoted to Production "... with those changes that are deemed necessary by the Credit Department." Apparently, they did not catch all of the "necessary changes" because in the first week, the Credit Department mailed 1,500 statements to delinquent customers with the Reminder Notice: "Pay up, or we'll rape your wife." Judging by the memo that was distributed to the MIS Department following this debacle, the rest of the organization failed to see the humour in this. ---- "Don't Worry.

Last year, I was invovled in the installation of a Novell Network for CMU's GSIA Department of External Affairs -- ie, the "soak the alumni for money" people. [GSIA: Graduate School of Industrial Administration. End Aside] Their database, in an obscure language/program that I never heard of (and can't remember) existed solely on the hard drive of the IBM Model 60 that was to become the file server -- naturally, it was the only machine in the office with 3.5" disks (the rest were IBM XT's) and without a 5.25" port. So, I asked to see their backup disks and original system disks before I did anything. Now, it seems that the company had been down a few months before, and taken the system disks back with them. The next time the department secretary went to Boston for training, they gave her copies of the disks. Or so they said. Funny thing was that the disks were hand-lettered "MacPaint". And it was a bootleg copy of MacPaint! I made two sets of backups of the database before I did anything (and successfully re-loaded them later), but as of the last I heard, they've NEVER gotten a copy of the program back from the company. However, they were TOLD to return the MacPaint disks! (Like, how the hell can you use MacPaint on a Model 60 running PC-DOS 3.3? Inquiring minds want to know...)

When we were first porting UN*X to our hardware we often had
crashes that would leave the file system in a state of disarry.
Going through the fsck routine of being asked if we wanted to
clear the file, etc got to be a hassle. So one of the programmers
added a "-y" option to fsck that would print out yes to the
question (so you could see what was going on), automatically
clear the file in question and continue. It was very handy. It
cut reboot times down dramatically. Until the first time "/"
was corrupted:
Directory "/" corrupted, do you wish to remove? YES
Directory "/" removed.
"-y" was removed forthwith.

This was told to me by a former supervisor (retired):
In the late 1960's, Pacific Telephone installed a new computer room on the
10th or 11th floor of a new highrise in downtown Los Angeles. The building
was one of the tallest around at that time. Its walls were all glass.
The computer had 20 or 30 tape drives and was to be used for a new system
that would run a transaction system during the day and a batch system at
night. The output from the daytime online system would feed the nighttime
batch system for master file updating. Some of the master file runs would
take hours.
Most of the testing was done during the daytime.
On the first day of production there were the usual problems and the
batch system was running behind schedule.
At dawn when the sun came up it shined through the windows on the tape
drives which immediately went into high speed rewind and unloaded the
tapes.
The sun had shined on the end-of-tape sensors which caused the tapes
to rewind.
After that one of the nightly duties of the graveyard shift supervisor
was to insure that the drapes were closed before the sun came up.

Whenever we used to make major changes to our operating system or transaction
processing system we were required to repeat a prior day's business to prove
the the system was ready for production.
Until about 10 years ago, we would do this by copying all the databases and
tapes for a day and run a series of tests on Saturdays. All the production
terminal operators would be at their terminals typing exactly the same things
that they had typed on the day being repeated.
All this was very expensive and error prone. Usually the tests would cause
a crash a few minutes after they started.
On one memorable day in 1976 the test was running very smoothly.
The computer room was filled with onlookers: operations people, systems
programmers, bigshots, vendor representatives, etc.
The console operator was continuously displaying the status of the system.
One common command was to display all the jobs in the system:
$dj 1-999
Everyone was pleased that the test was going so well until around
4 PM when all the jobs suddenly stopped running.
Concern turned to elation when the console operator confessed that he
had mistakenly typed:
$cj 1-999
Which *cancelled* all the jobs in the system!

In the late 60's, I was working in computer operations, babysitting/feeding
several 360/30's serving as administrative and accounting systems for a large
aerospace corp. Besides the constant jobs of loading mag tapes and emptying
and reloading printers, there were occasional paper tapes to be punched. The
high-speed :{) paper tape drive could be (mechanically) for 5,6,7, or 8-level
paper tapes, although I can't ever remember running anything but 8-level jobs.
When the mag-to-paper tape job was started, one of the operator inputs was
to answer "Is the paper tape punch set for 8-level tape?". Of course, the
answer was invariably "yes". Once in a great while, someone (on another shift,
of course! :{) ) would have left the drive set for fewer rows. Immediately
after the operator would enter "yes" the system would reply "Set the paper
tape punch for 8 levels, dummy!".
Certainly, this was a rude response; more to the point, why didn't the
idiot application programmer *TEST* the U^%$*&)( setting rather than
asking, when it was possible to check it?!?

Wow. Maybe *that* explains things a little differently about the computer center I used to work at. Our computer room was set back from the front of the building, but had floor-to-ceiling windowed wall that looked out onto (or in from) what used to be a big glassed-in lobby. At night (usually at the start of 2nd shift) drapes were pulled inside the computer room. Now, I had been told that it was to prevent snipers being able to see into the place at night. The sun-in-the-morning story sounds more plausible, as there were many tape drives facing towards the windowed wall, and the lobby faced east... perfect for the sun to hit the BOT/EOT sensors. Anyway, the daytime operators had to dressed in a more professional manner, while the off-shift operators (when we had no corporate visitors peering into the "fishbowl") wore just about what we felt like. -- _____________________________________________________________________________ Peg Shambo | Sophisticated Lady, I know. | Ellington/ peggy@ddsw1.mcs.com | You miss the Love you had long ago | Mills/Parish | And when nobody is nigh, you cry. |

A few years back I had to write a program in Pascal with 'bullet-proof' input routines for use by office staff with little knowledge of anything other than wordprocessors.

Well, since my documentation explained this feature, the group I wrote it for decided to test it in their acceptance test. When I received the test report, they noted that my input routines didn't work correctly. Then I noticed in the appendix, a list of the keys that they felt were in error. This list included 'Control + M', 'Control + H', ... etc. (They knew about the control key from their wordprocessors). I tried to explain to them how control sequences work, that I couldn't fix it in software, and that it wouldn't be very desirable to change the terminals to not generate the control sequences, and they finally relented.

They made him an offer- they would supply an IBM PC for him to destroy in their presence. If he was successful, he would tell them how he did it, and they'd give him a free (functioning) IBM. Well, the appointed day came, and so did IBM. They set up their machine on a table and sat down to watch. The student quietly inserted a disk and turned the machine on, then sat down. After the memory check, the computer loaded the program from disk. The drive kept running for a while. Soon the machine started to shake, then shake violently, and would have walked itself off the table had the power supply not shut down. It was quite dead and emitting that funny burnt-resistor smell. The IBM reps checked it and declared it irreppairable. My brother's friend now has a nice IBM PC he uses for terminal emulation, and support for his plants. This is how it worked- the program simply sped up and slowed down the disk drive until it found the resonant frequency of the case of he machine. The case slowly started to resonate, and soon the whole machine would be shaking. This would cause the cards and other innards to flex, and contacts would be made and broken, destroying chips left and right. Eventually something would short and the power supply would go. Pretty effective, tho it did take a while. Remember kids, don't try this at home. We're professionals here. :) "I keep trying to think but nothing happens..." tjpadula@phoenix.Princeton.EDU Thomas J.

Years ago, I did some Data General consulting out of my/my parents house.
Some memories: There was a rev of AOS (3.something, I believe) that could
be crashed easily - just have several users hold down the tab & repeat keys.
Something about the system expanding the tabs to 8 spaces, which filled up
and overflowed the ring buffers and clobbered OS code. Instant system panic.
Or the 12.5 mb (14" platter!) winchester disk that could become a 25mb by
moving a jumper and reformatting it.
Or the old Nova 800/1200 4k core (!) memories that could be burnt up
if you stored a 0 at address 0 and then jumped to that location (octal 0=JMP 0).
Or the story that the Nova 1200 (with a 1200ns clock time) was "invented"
to use up the warehouse(s) full of core stacks that were just a little too
slow for the Nova 800...
Or the fact that changing 5 microcode ROMs would change a Nova 4 into a
Eclipse S-140...
Or you could suck out the solder and pour in the chips and convert a 128k
16-bit Nova memory board into a 256k Eclipse 21-bit error-correcting memory
board...
Back in school we had a Burroughs 3500 (Pasadena City College). I was
doing some "lets see what happens" programming (in Fortran) and the
instructor politely asked that I let him look at my stuff before I submitted
it (overnight batch). You see, there was this bug that another student
found: You define a gigantic block common (3-d complex matrices will do it...)
and then zero it. The system overflows memory to disk (Burroughs had virtual
memory loooong before IBM) and there was this bug in the max size of the
virtual file check routine.... Before this earlier student's bug was caught
they staff had to do a half a dozen system reloads/regens - from a dozen
boxes of binary punch cards! His memory array was larger than _all_ of the
disk the system had on it, and he had zeroed all of it...
A story that a friend tells is where a classmate figured out how to set
the schools IBM 1620 system memory to all parity checks... The system was
called the CADET, which stood for "Can't Add, Doesn't Even Try - the machine
did all it's math by table lookup (yes, that was one machine that could tell
you that 2+2=5 with a straight face - just diddle a few bits in memory).
Or the rev 1.0 of a OS that deleted the file, but forgot to mark the space
as free... It didn't take long for a 10mb disk to shrink to < 1mb...
BTW - the Nova 4 in my dining room is for sale. 128k, 16-slot chassis,
and several peripherals, including a DECwriter III as the system printer.
Boots RDOS, multi-user basic. Wichester disk, 8" floppy, 2400' mag tape,
dual consoles, extras. Make offer.

The Prince of Darkness informed him that he could arrange it so that he would win _all_ of his court cases, make twice as much money, work half as hard, be appointed to the Supreme Court by the age of 49, and live to be 90. All he had to do was promise the devil his soul, the soul of his wife, his children, and the souls of all of his ancestors. The lawyer thought for a minute, and then responded: "So what's the catch?"

A modification/upgrade to the Qume was introduced on the market, where a dealer who was not very electrically inclined could upgrade the normal 16k buffer to a full 64k buffer for $200. The upgrade was to remove a series of 6 jumpers, and replace them with a plug in dip switch.

Something >about the clock being forced to run at too high a speed. (Can anyone confirm/ >deny this?) It's true, the Fat40 (4032) would do this. It was called the Killer Poke. Anyone with money to burn could try this one to amaze thier friends :-) Especially after telling them that there's no way to hurt a computer from the keyboard. For full points, any body remember the value? The only one I remember from my Fat40 days was the basic instruction WAIT, which was supposed to wait until a memory location reached a certain value (for monitoring memory mapped i/o or ISRs). If you typed WAIT 6502,n it would respond "MICROSOFT!" n times. This is evidently a way to protect your stuff against piracy. If somebody claimed they just mimiced your program without copying it, you could use the undocumented quirks as evidence. There was a word process for the Pet that would play Pomp and Circumstance if you held down a certain 3 keys!

Wayne says: (I don't take anything that Wayne says seriously) I'm not sure about this one but the TRS-80 Model II computer from Radio Shack had a problem that I was told about. Never tried it (I own one but _I'm_ not going to try it!) but supposedly if you turned off the video (control bit on one of the ports), the power supply started building potential and a freaking big capacitor blew apart. Supposedly it happened one day at a Radio Shack repair shop and the top of the cap buried itself in a cinderblock wall. Zap Savage Savage Research "Making Tomorrow's Mistakes Today" P.S.

I wouldn't call it a full-sized court, but there is indeed a basketball rim and backboard in a maintenance room at the top of the Matterhorn. It was originally put up (in 1978) as part of an elaborate pun that you can no doubt figure out yourself (Matterhorn, "hoops", get it?) but turned out to be so much fun that it hung around until at least 1984. Not having worked at the 'Land in a while, I can't say if it is still there or not. -- Scott
