I can't get a good reading off the 0120. I think the circuit is trying to run from the power from the multimeter. What I will try is a setup similar to what I used earlier and set up the buck converter to 4.5v then I'll stick the multimeter inline and measure the current. The 7300 measurement...

I pulled the 7300/200 board so I could poke at the CUDA circuitry briefly. I wanted to pull it to catalogue the electrolytics anyway. The 0120 on the 7300 doesn't exhibit the voltage drop like on the 5200. It was something negligible like .01v difference. So I guess I may have found the general...

demik, If I had another compatible-ish board I'd have already tried that but sadly I don't. Also apologies I haven't quite got the hang of how this forum's formatting works so I'm keeping it plain. Weird things happen. I've done what I could with the PSU anyway. Having the logic board trapped...

Let's call it CUDA. I find the other names confusing and I'm not even sure I'm using the right one. I suspected that the 0120 did something like you say but I couldn't find a match for something so generic online. Thanks for the schematic. That's super helpful. I'll be working through it. Edit...

Fairly recently I bought a couple of PPC macs in my far-too-long quest to have a working Old World PPC Mac again. One of which was a 5200CD. I got it working mostly, except for sound. And the HDD was very tired. Then it stopped working. Powers on. No power light. No boot chime or other signs of...
