:Unix! : :I've got _all_ the original CBM stuff for the VIC-20 and C-64, hardware :and hardcopy. Even some aftermarket FDDs. : :I poked a _lot_ of stuff from Compute!, including the assembler, and :have several of their wire-bound books, too. : :I've got the 6502 monitor and 300bps modem cartridges, and if I dig :around, I'll bet I can find the breadboarded interface to an audio :cassette player I built so long ago from a Byte article! I soldered :"reset wires" to both machines' mobos, too. : :I've still got all software I accumulated on floppy (even some cool EA :games, and MicroProse's Gunship), but I have no idea if any of it is :still readable. : :Those were the days, my friends... :Dave
Ah yes. By the time I was ready to throw my PET away the hardware inside was so hacked up I don't think anybody but me could boot the thing. I had replaced the character generator ROM with a RAM and wired in a wire select to an unused bank, which meant the screen was spaghetti on power-up until i LOAD'd a copy of the character set. I had the machine language monitor extension rom. I had wired in an extra 16K of dynamic ram, giving me 48K total (bank selected) (imagine piggy-backing a bank of 14 or 16 pin DIPs on another bank and soldering each lead, except for the select, to the one below). I had the NMI button hooked up, of course, and I brought the TTL video lead for the monitor out to act as a poor man's oscilliscope. The insides of that box was a mess. These days traces or so tiny and chip leads are so close together (not to mention the 6+ layer boards!) that hacking a PC's hardware is pretty close to impossible. But it's funny... I never had a desire to hack up my C64's or my Amiga's. I guess there enough fun things to do with them that hardware hacking wasn't necessary. -Matt To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
