[comp.misc] More 1130/1403 stuff

kumard@sunybcs.UUCP (02/12/87)

	I am surprised no one volunteered to tell our-side of the
	1130 story. My undergrad school in India (Birla Institute
	of Technology & Science (BITS),Pilani) has had an 1130
	since 1972. It has a 1403 printer. For a long long time
	(about 8 years!) it was the backbone of the CS Department
	and the School. All Academic computing (like student records)
	time-table scheduling, and student services were handled by
	this giant (The scholl has about 2500 students). 

	I am greatful that it was my first machine. Simply because
	we were able to play with it as we liked. Here's a few
	stories (some of them were legends told to me by alumni):

	1. One wonderd what would happen if you forced read a card
	   with a giant hole punched in it. It was tried and the
	   card reader jammed.

	2. One used to sneak into the computer room at night to play
	   with it. However, the operators kept a log of system usage
	   by recording the meter-readings on all devices.
	   A technique for resetting the meters back was figured out.
	   After a night of hacking, they were reset. authorities
	   used to wonder why the electricity bills were so high.

	3. On one those nights, someone decided to write his own
	   Operating System, to fool the operator. It was planted
	   on the disk for the operator to load in the morning. He
	   switches the machine, shoves in the Cold-start card, and
	   the printer says,
	   1403: I feel sick today, put me off
	   (keeps printing this repeatedly)
	   (Operator thinks something is wrong, goes to switch it off)
	   1403: Oh! No, you can't put me off!
	   (Operator starts to put the printer off-line)
	   1403: No, don't even try!
	   ........and so one this kind of stuff went on until the
	   operator got sick of it (after several power off, retries)
	   and called in the services of the Chief of the Computer
	   Center, who immediately know what had happened. Luckily
	   he had a good sense of humor.

	4. Someone got hold of this FORTRAN program that printed a lot
	   of garbage for a minute. The sounds the printer made were
	   the exact notes of the Indian National Anthem! After the
	   third run, the printer chain gave up. The program deck was
	   confiscated by the Chief.

	5. With every such machine, the Chief also gets a reputation.
	   This Chief had a reputation for tinkering with the machine.
	   Once, he spent the whole day pullingthe 1403 apart, and by
	   evening it was all over the room. There was a power cut
	   (power cuts were normal there), everyone went out for a
	   coffee. Chief lit a candle in the room and started fiddling.
	   Power came back after 2 hours. The floor was clean and the
	   1403 stood in one piece with chief standing next to it.
	   Asks thge operator to switch power on, and it worked.

	6. The same chief installed a VLSI Floating Point Unit,
	   lodged it in the Multiplexer housing, and incorporated
	   it in the FORTRAN compiler in a 27-th pass (it already
	   had 26 passes).

	And there's tons more of that stuff!!!

	Deepak.

	At my college a favorite stunt was to punch cards with all rows
and columns punched - leaving a Swiss cheese card with little mechanical
strength - but undetectable when viewed from the outside of a deck.  (It
was also neat to hear the sound of a 513 reproducer when duplicating these
"cards".)
	There is no way that a card like this could pass through any 1402 or
unit record equipment reader without causing a nasty jam.  A "fun" thing to do
was to place some cards punched like this in some unsuspecting person's
program deck.  This kind of jam was _worse_ that the traditional "accordian"
card jam; it was usually Card Saw Time.  Anyone remember the little card saws
for use in severe card jams?

	While my first hands-on computer experience was with a 1401 used
by a particular department, my college had a 7094 as the computing center
mainframe.  This beast ran a tape operating system called IBSYS.  All
students, staff and faculty authorized to submit jobs were issued a supply
of job cards having prepunched fields for job number, user id and department,
and time limit.  Students obviously wanted more than their allocated cpu time,
but the administration thought it had licked the problem of job card
counterfeiting (i.e., with a longer cpu time limit) by using cards that were
on a special colored and striped stock; needless to say, this blank card
stock was well "guarded".
	However, for enterprising students there was a way around this
situation: Since the stripes never covered the columns where the time limit
was punched, conventional colored card chad could be carefully glued to
cover the zero punches in the tens and hundred minutes columns - thereby
permitting the card to be repunched with a higher time limit!  A good job
of covering the zero punches was difficult to detect.

	Another "fun" thing to do was plant a card in some victim's program
deck which was punched as ``$STOP'' - the IBSYS JCL command that halted the
the system.  After this became a chronic "problem", IBSYS was patched to
change this command to something else.

	An IBM CE gave me an Autocoder program that ran on the 1401 and
played the U.S. national anthem.  It always amazed me how someone had
the _time_ to determine the character sequences required to generate
specific musical notes, and then put it all together in the proper
rhythm for a song!

I had the same problem, needing to create an "illegal" job card.  Where I was
at the time (Cornell, late 60's) had a priority system, and during the day
they would not load jobs that were below a certain priority (that mere under-
grads did not have!).  I solved the problem (and actually got away with it for
a while) by placing a dummy job at the high priority, with a real
Job Card, in front of my real job, with a job card made of regular stock.
The system would bounce the phoney job but then execute my real, low priority
job.

//JOB...PRI=6             (real job card)
//
//JOB...PRI=4             (regular stock)
//EXEC
...
//

Additional comment: I never liked using terminals until display oriented 
editors appeared.  It was so much easier to edit a deck of cards (now that
was real WYSIWYG!).

REMEMBER! I still have one! Along with a core plane from the IBM 1620 that
I took my first Computer Science course on.  Our big charge was to write
programs that would cause all the lights on the console to come on.

I really miss all those lights.  Back then it was easy to tell when you were
is a non-terminating loop.  The light pattern just kept repeating.

     [ Gee, I hope I'm not showing my age by saying my first computer
interaction was with an 1130 with a 026 keypunch(-;!!!!]

     Back in my undergraduate days, I knew someone who had written a
program that, if one put an AM radio on the 1130 console, would play
electronic music through the radio from the RF generated by th3 1130.
Very impressive (at the time, anyway). This would only work if the
1130 was in a room by itself, so the radio would only pick up the RF
from the 1130. This acquainance had actually transcribed about 20-30
songs, and punched them into cards for the data input into the program.

We used to do the same thing, except that it had a useful purpose.
We had a program that would punch all the holes in a stack of cards.
The little punchouts made for fine confetti at a variety of celebrations.
Of course, the name of the program was "mulch."

We have the 1130 sitting around in a closet somewhere waiting for the
price of gold to go up (no kidding).  Then, it's off to the smelting
shop.

I still have the "parity check" light for old times sake.

Only if you don't like the people it got thrown on - that chad has
*sharp* corners.  But there were many uses for the punched-out cards:

I used to have a deck of them sitting on my desk (with normal-looking
cards on the faces) waiting for someone to pick it up.  Someone old enough
to have worked with cards was always startled that the deck was about
half the weight they were expecting.

At Brock University, some students taped the punched-out cards into
strips and hung them as curtains for their office windows.

Oh my god, I forgot all about the "MUSIC" program for the IBM 1130.
I tried for almost a week to figure out what the#$%@#% it was doing.
I found out when someone left a radio in the room and I ran the program.

My first introduction to the IBM portapunch (a plastic device used to hold
perforated punchcards so you could, by hand, push out the holes with a stylus)
was when a desperate social sciences type came into my office asking for new
cards for this, this .. thing?! It turned out that what he really needed was
copies of one card & then to ad two punches, punches that a cardpunch could make Well I was pretty proud of myself, having been one of the last people on the
earth's face required to actually use the 029.  I grabbed his deck, loaded it
alternately with blank cards, hit dup, and the brushes popped out every
hole on that perforated card.  Talk about one mad grad student.  He didn't
even care that the technology was too old and useless for me to held responsible
for this action.

Yes, I remember card saws.  Had to use 'em all the time on the card
reader on a 370/135 RJE station (I'm just a couple of seasons later
than most of these computer paleontologists) and the 029 keypunches,
particularly when I (or one of my friends) put a "dup all" card on
the keypunch drum and left an "all-punched" card in the bottom of the
hopper as a booby trap.  The card saws made great picks for getting
into the file cabinets, too.

A DEC CE who (until about 1978) worked on a PDP-8 I used to use had an
RX01 floppy full of programs which would play music on the beast.  You
listened to the music by putting an AM radio near the backplane and
tuning it to somewhere in the upper third (I believe) of the dial...

There actually used to be available from DECUS a program written in
assembler for the PDP9 (which could thus be hacked to run on the PDP15)
to cycle the console lights so that a radio placed nearby would play
some Bach piece in full four-part harmony.

And to think the folks playing with their micros with off-the-shelf
ployphonic synthesizer boards think they're doing something clever...

Ah yes ... memories this comment brings back of my summer job as a tab
operator in a local business.  

There was a programmer who liked to slip one of these 80x12 cards into
the decks he brought over to have duplicated.  He seemed to get his
jollies listening to the gang punch as it went 
	crunch
	crunch
	KWHAM		<floor shakes dramatically here
	crunch
	crunch
as it reproduced his deck.  Once he put a number of them into a deck,
one after the other.  The sound effects went something like
	crunch
	crunch 
	KWHAM		<floor shakes dramatically here
	KWHAM		<floor shakes dramatically here again
	KWHAM		<floor shakes dramatically here again
	plink
	<long silence>
Afterwards we found that some of the chad had jammed between two of the
punch dies and resulted in two of the dies snapping.  The gangpunch was
dead for about three days until all of the necessary parts could be
found and brought to the site.  Nobody ratted on the programmer, but he
never slipped another 80x12 card into one of his decks again!

The machine is the reproducing punch, which is capable of gangpunching
but that is not card duplication as you described.  Gangpunching is
punching columns from a previous card into successive cards.  For real
slick operations, you could program when to switch masters (interspersed
master gangpunching).

Ah, it brings back such memories.  I used to program those things.  My
favorite feature is that if you wanted machine readable output from the
402 accounting machine, you dragged this big 80x12 contact plug over
to the 514 and punched some cards.

Before the FCC AM interference regulations were passed, you used to
be able to do this sort of thing with just about any machine.
I remember playing early TRS-80 games, like "Invasion Force",
and using a large AM radio placed near the machine to produce
appropriate sound effects.  In fact, TRS-80 programmers got so good
at producing the correct sound-creating loops that some of the later
games actually had VOICE effects!

Yes - I still have my TRS-80 Model I and remember the sound effects that were
produced in that manner. However, it wasn't QUITE as impressive as it might
seem. What was really going on was that the game sent out the sound in the form
of square wave pulses to the cassette port (which is why you could get clearer
sound by hooking up a speaker to the AUX jack). It just happened to be true that
the RFI from the machine was bad enough to also make those sounds audible on an
unused AM frequency...

Although this doesn't quite rank with the more ingenious anecdotes
already posted, I have a recollection to contribute to the pot.

At my Alma Mater (Yeshiva University in N.Y.) the student computer
room was (is?) located in the science building which was closed on
weekends (and I mean closed, as in locked and with no heat during the
winter - brrrrr!.) But the University had it's own computer room in
the same building which had to be in operation from Sunday through
Friday (they gave him heat, though.)

At night and on weekends the operator could gain access to the building by
operating an electronic combination lock on a side entrance. Somehow,
the students always found out the combination and entered the building
to use the computer room (the university policy then was that no students
were permitted in that building when it was "closed" due to insurance
requirements, etc so the students never got the combination through
"proper" channels.)

Well, in N.Y. during the winter a brick building without heat could
chill a person right down to the bone. Fortunately we had an IBM 1130.
Even when the students discovered the UNIX OS, they still needed the
IBM 1130 - those things made great space heaters!

There was a few months between when we last used our 1130 and when it was
hauled away for scrap. During that time, the student operators had a pizza
party in the same room where the 1130 resided. As I recall, we kept the
pizzas warm by firing up the 1130 and putting the boxes of pizza inside the
1132 printer.

Never have found a better pizza warmer...
