The power button on the keybord grounds like pin 4 (I think, it might be pin 2) and I think that the one on the mother board does too. I think that this signals something in the power managment chip to send a signal to the PSU through one wire or another. I want to tap this wire from the Motherboard to the PSU so that instead of going to one power supply it goes to both. When the power button is hit both power supplies come on but only one will drive the mother board: One of them will drive the motherboard, the SCSI devices and the secondary monitor and the other the ATA devices and the fans and that only.
Does anyone know of this wire? I only have 3 PSUs around here and don't want to blow one up trying to dolve this issue.

You want an "N+1" power supply system, right?
No way with the 8500 power supply design.
Apple's ANS 700 offered an N+1 option. Plug-in power supplies, too.
Now, if you had a Beige G3 there would be something out there for you as the G3 MT systems utilize a conventional ATX power supply, and there are several N+1 solutions for ATX machines.
