Hi, All, Back on that 2001-8 board... it's a P/N 320008, original board. It has a 5-pin power supply connector. From the schematics, pin 3 is GND, pin 2 is unreg 9VDC, and there's a pair of half-wave diodes from pins 1 and 5 to pin 4. I want to run this board in a more modern PET chassis (so far I've been using external +5VDC through TP1 down by the internal cassette port). I've never been able to locate a chassis-specific schematic of any PET to match up the rectifiers and regulators on the board with the transformer and filter cap in the chassis. Can anyone point me to such a document on zimmers.net or anywhere else? I have the general idea of what needs to happen, but I'd rather not fry my only #320008 board trying to put it someplace "interesting" because I failed to understand some important detail.
