Lisa 2 Power Supply Pinout?

Not really 68k Macs, but certainly Vintage!

Lisa 2 Power Supply Pinout?

Postby DragonKid » 18 Oct 2009, 04:57

So, I've recently discovered that Carnegie Mellon's computer club owns a Lisa 2/10 (unfortunately with Mac XL mods). I'm trying to get this machine operable again, but we want to bench-test the power supply before we attempt to boot the machine with it. Does anyone here know the pinout for the edge connector on the power supply unit? I've found a 1983 copy of the Lisa Hardware Manual, and know what the correct voltages/currents are, and how to turn on the unit, but I don't know where said voltages should appear.
Stuff I Own:

iMac G3/400 Tangerine (OS X 10.4), Macintosh LC 580, PowerMac G3 Beige, Macintosh SE, PowerBook 150.

I couldn't make heads or tails of the pinout on the schematic linked in the previous reply. I found schematics for the 1.8 amp power supply in the LisaList groups in Google Groups (groups.google.com) here:

The 1.8 amp power supply schematic has a very good pinout description. Seems to me that since the 1.8 amp and 1.2 amp power supply work in the same systems,
the pinout ought to be the same for both. Hope this helps.
