Got it taken care of. Aside from some of my scratches trying to figure things out, it's hard to notice the bodge.

Wonderful! That is a best case scenario, given the situation. Also, I am especially thankful for the link to the schematics. (Though the direct link above didn't work. It seems it is now updated to this one.) I did not have them, and they are remarkably clear and easy to read. Thanks again!

I'm working on restoring a Performa 575, and, as usual, things started with a recap. The board was not battery bombed, but it was close... clearly bad chemicals had been wafting from the battery, and corrosion had impacted the board. I started the recap with hot tweezers before switching back...

I wanted to jump back on this thread to say I got this up and running on a Raspberry Pi 5 which is also hosting my RetroNAS setup. I'm now building my database. It is a very polished project! Thank you very much.

Wiring up a DIN connection is never fun, but it happened. I was able to determine which pin on the motherboard was connected to vcc and which went to ground. After that, it was a guess which was the clock and which was data. I messed up due to a bad diagram, but once I was looking at the correct...

Thanks to some help on the Vogons forum, I figured out the problem with my CPU and cache controller. The orientation was correct, but the chips were swapped! The CPU goes in U386, next to the FPU, and the cache controller goes in U385. Now that I know that, I can see it identifies the chips on...

I picked this project up again, and I've had some success, but not enough. I was able to find the cause of the short on the +12V rail. By injecting 1V at 2Amps into the +12V power pin, and using my thermal camera, I saw a 10uF ceramic cap was getting hot near the PSU connector. After replacing...

I've got a Kaiweets KTI-W01 thermal camera running firmware version 1.4.1. I have downloaded the latest version of the IRImageTools software from the Kaiweets website (version 1.0.1.22 -- the camera came with 1.0.1.14). The software is basic and the documentation very thin. Does anyone know...

I ordered the Korad KA3005D, which may not be original, but worth a shot. I was tempted by the Frinsi DPS-150. The Korad should arrive soon and I’ll put it through its paces.

I edited my post above because I was wrong… The GitHub page for the original Power Up IIusi design is still available at https://github.com/CayMac-Team/IIsi-PCB-Replacement.

If I remember correctly, I was seeing the ripple on the 12V DC before it got to the PicoPSU. So, it seemed to be coming from the AC/DC converter.

I’ve had the Mac-o-Meter plugged into the external floppy port while running the IIsi through its paces and not noticed any significant voltage drop. However, the heaviest load I’ve put on it is a PowerPC upgrade card and a BlueSCSI. Like its LC siblings, the IIsi was not made for serious...

I should have added that I have a couple of the earlier PicoPSU boards, complete with parts (except with IIsi wiring harness and mains plug), available if anyone want to pay the shipping to get them.

I have built both versions of CayMac’s Power Up IIusi. The first used a PicoPSU, and the second is the model in this thread with separate Mean Well units. I prefer the Mean Well version because it requires no modification to the mains outlet and it produces cleaner power. The PicoPSU version...

I tried running it through the Container Station GUI, which lets you bring in yaml files. I suspect this was my problem. An SSH terminal may be a better method.
