its been since 1999 when i had my 6100. it was my VERY first owned powerPC mac, and even then, thats how i had to start her up. because of a bad PRAM batt.
its been long since gone. but it was fun.
My second owned PPC macintosh was a "hackintosh 5400" Basically, the analog board we bad. shorted HOT, bad flyback.
So i completely gutted the machine, and cut the plug going to the secondary power supply. I wired up an old AT style power supply into the wires running to the 5400 system board.
it worked great, i had to tap a VGA monitor into the video wiring off the logic board connector as well. It had some ghosting because of impedance mismatching in the wires, but it worked.
I had that thing until eventually i ended up with a performa 6200 which took the same type of logic boards.
