Did you plug the BlueSCSI in or unplug it while the machine was powered on? Not sure if that would necessarily cause your specific issues, but plugging/unplugging SCSI(or ADB- the keyboard/mouse port) while the computer is on is not a good idea and could cause damage

Also while you have it open, on the power supply board there's a 20ish pin connector that's goes to a cable for power for the motherboard(very similar to an ATX power cable) Reflow that connector, because those joints tend to crack as well and cause issues.

If you're using a bluescsi.ini config file on the SD card, make sure you don't have the debug mode turned on. That could add some slowness. Other than that, yeah could definitely be the SD card or the SCSI driver.

assuming you're looking for the STL files and not like, the raw CAD design files-they're here https://github.com/bbenchoff/RackmountMac (not linked to on his page directly, but had to go through the github link and find it there) I've got an old Sonicwall NSA2600 that I'm planning to use the...

Awesome to see that helped, and now I definitely need to reflow mine! funny that it ended up being a relatively simple thing that all of us typically do with compact Macs. Thank you to everyone that helped narrow down this issue, but particular shoutout to AwkwardPotato, and Techknight(who...

Mine are not looking great either, so I think we may be on to something hopefully

I didn't reflow any solder joints on the power supply side, so probably not a bad idea to do that(and for me to do that as well)

Yeah, I had to use a piece of breadboard wire(but a paperclip should work too). negitive probe you can just attach to a metal part of the chassis if you have a clip on connector. If there's anything I can do as far as getting measurements or pictures or whatever to help troubleshoot ried's...

When you have a chance, see if you can measure the -12v line on your power supply when it has the issue. Looking at the power connector on the board, it's pin 12 AwkwardPotatos theory of that line going out of spec seems like a reasonable one

(not to turn this thread into a sound related post. i'd edit the above comment, but am way past the 45 minute edit window. besides a final update on what the sound issue ends up being, I'll put any new sound issue questions in a new thread) I swapped the chip, and have some success! sound...

Good news is, I've run mine for like an hour+ a couple of times this weekend and it's been stable. I checked the -12v and it's showing pretty much perfect. Running it again without the shielding on, in hopes that it will do it again, so I can see if there's a drop in the -12v rail. My last...

video still going strong. will test some more tomorrow still no audio though. both headphones and internal speakers. tried without AIO ribbon connected, same thing reseated personality card, same issue I checked with mac84, he has a g3 AIO board on his bench, headphones plugged into...

redid all the joints that go to the CRT tube, and the connectors. both analog board and neckboard. no difference. in fact, as soon as i turned it on it was the messed up display. One theory I have(for mine at least), and potentially ried's) is heat. When I was messing with it yesterday, just...

let it sit for like an hour. Screen is normal again. Same voltage from that last pin still. About 127v. So that’s not the issue. Maybe reflowing all the connectors might help? Edit: lasted about 10 minutes before funkyness again

So a bit of an update I went to test the voltages from the back of the neckboard, and I turned the machine on, and display was fine!(except needing a focus ajustment). Had it running for about 10 minutes, and then it started having the issues again. (No sound, but I have the motherboard out...

I'll hopefully have a chance to check either tomorrow night or this weekend. Would an issue with the G2 or Focus wiring potentially cause this? I had to splice+solder them from the neckboard to the new flyback
