What manner of hacker is this? "Testing", indeed.

well, *do* I know how to post here? One easy way to find out. ObHack: retapping the divide chain on a TRS-80 so the heartbeat interrupt came 4 times as frequently as normal, fast enough to keep up with chars from a 1200 bps modem rather than only 300 baud. Oh, and the interrupt-driven serial driver, of course. The BAD old days, but sometimes I miss being able to just open up the machine and *fix* it if I didn't like the design. Try that with an 8-layer board and surface-mount technology... -jeffB (Jeff Brandenburg, Va. Tech CS) Master of 16-pin DIPs I'll develop a .sig when I get in the habit of .posting.

Try >that with an 8-layer board and surface-mount technology... Those were the days... All the stuff I did to my TRS-80: Doubled the clock speed Added an extra 2102 for lower case Built a board to replace the character generator with a custom-programmed 2716 for *decent* lower case. Just for the fun of it, I sacrificed the "graphics", and put the Greek, Russian, and Hebrew alphabets in the upper half of the ROM. Eventually I changed that back; too many games wouldn't work. Added a board from Exatron to put 64K in the keyboard. (I never did get an expansion interface.) Hacked the video circuitry to test vertical retrace from an IO port, so I could write a program to test for retrace, and avoid snow on the screen. While I was at it, used an output line to switch 32 column mode from even locations to odd locations, giving the effect of two pages of video memory in 32 column mode. Add the Dennis (?) mod from 80 Microcomputing to de-snow the screen for everything by adding wait states. -- Caution: Thermostellar device. Mike Van Pelt Handle with care.

Wow! This reminds me of things! I also added lower case with `true'
decenders... made quite the difference.
Added a switch to reset *reset-proof* programs and such so I could jump
into a monitor program and hack about.
Added some goodies to port 255 to use it as a simple but workable
2-bit (!!) sampler. Yow.
Wrote a printer driver (tsr) to change outgoing text into the font of
your choice... Even got it published in Micro-80.
Modified all the Big-5 games (and others worthy of such :-) to use an
Atari joystick (which had a socket hack installed). This alone saved my
keyboard for better things (like cleaning it once a-month and those
blessed edge-cards...).
My favorite things were hacking on disks and such. Pretty neat.
Something I noticed which was *really* funny for me... Quite a few
programs that I bought would come on a disk that was altered to make
it self-booting (and sometimes copy protected - no bother though).
These disks, it seems, were generated from a master working copy using a
sector (or bit) copy. A given disk would sometimes have an okay directory
(which helped!)... Looking at the dir, one would notice the presense
of other files - like the *commented* source code. What a find for some-
one who wants to know how the code works... All one had to was either fix
the dir entry or track the individual sectors down... :-)
Hack on dudes,
Joe

> Wow! This reminds me of things! I also added lower case with `true' > decenders... made quite the difference. Reminds me of the font editor and text stuff I did on the Apple-II in Forth. Used the "hi-res" graphics to display the fonts, and even with the overhead of Forth it was quite fast... certainly faster then using the BIOS on an IBM-PC... which is in assembly on a much faster CPU. Of course you all know that the IBM-PC ROM BIOS is a hack in another sense. Anyway, to make the characters look nicer on a B&W monitor I used the half-pixel shift the Apple-II provides for the second set of colors to give the characters nice curved sides. The resulting font looked way nicer than anything Apple had. I also did Turtle Graphics in the same Forth, but it was really slow until Karl modified it to use CAT Graphics from BYTE magazine... back when BYTE was *really* the Small Systems Journal instead of Just Another Damned IBM-PC Rag. -- (peter@taronga.uucp.ferranti.com) `-_-' 'U`

This will probably increase slightly the difficulty of posting. Once you find out however it is very easy to post again. In the body we could have a line saying who it is actually from like I have. For a little more difficulty, we can have a specific FULL address, like anonymous@bullshit.edu. All these are pretty trivial hacks but they would also discourage automated postings from Rutgers and other places.

Try to keep your posts to length 75 or less, lines that wrap around into two are aggravating to use in VI. Your point is not very helpful. If someone can post here, s/he can also do the trivial hack (sorry - want of a better word) to forge a message. This will not help much, and incase of the rutgers gateway, I am sure the postmasters are astute enough to forge a message. Or are they?

Test. Obhack: After getting frustrated with Rogue for the Mac, I started looking through it with Resource Editor and FEdit. I found a Wizard screen in Resource Editor that I couldn't seem to call from the program. Around the same time, a friend found the name Mr. Mctesq (I might have botched the spelling, it's been a long time) sitting alone in memory. Putting 2 and 2 together (Hurrah for collaboration) we typed in Mr. Mctesq as the character name and were instant wizard. (Gobs of cool powers then. Sort of like superuser) Of course, after cheating too much, and getting too much experience, the level title changed to "cheater" Does that count?

Using the Norton Utilities, I was poking through MORIA.EXE on my PC and managed to find passwords for the wizard and and god modes. If you die inn one of these modes, you won't make the High score list, but otherwise, the game works normally. Of course the game is more ineresting if you don't "cheat". Jim
