The psu is from a Toshiba T1200. A few years ago I found it in the trash, brought it home and decided to try power it up without doing any research, then it showed the red blinking light, only later I decide to open it and discovered that the capacitors were leaking. As i was inexperienced I didn’t know how badly I messed it up so i decided to start disassembling it and creating a wiring diagram to help troubleshoot the board which got me to some places as I could switch some of the visually broken parts. It’s been about a year since I last worked on it and have decided to work on it and ask as many questions while the few people who have a working one of these or knowledge that might help me. I thought I should at least check if the rest of the computer is ok and attempt to power it up with some desktop power supplies, I’m just not entirely sure how I should wire it so I don't create any magic smoke. How would I create -22 volts and +5 volts while using a dc desktop power supply ? Where should I connect the ground for the -22 and +5 ?
