Hi all,
Apologies for the long hiatus. Truthfully, I have been sitting on this for well over a year now and just don't have the motivation. I've decided to release the KiCad files on GitHub.

I have tested the latest revision on a few different...
I modified and used Elliot's script and his RezHex tool to copy a modified (without the 68k stuff) 7.6.1 system file onto my PowerBook 1400. I have been using it for a few days with a 128GB SD card and have only run into one issue (which was entirely my fault).
The issue was forgetting to copy...
I went ahead and did further testing. So far, everything has worked well. The only issue has been the cracked solder joint on the PicoPSU mentioned above. I have tested the adapter with the following hardware:
Chassis:
63x
6200
Motherboard:
820-0548-B (63x)
820-0685-B (6200)
820-0751-A...
I can't believe it! My PicoPSU had a cracked solder joint. That's it. That's the problem. The PCB worked this whole time. Ahhhhhh!
Thanks for the feedback It is hugely appreciated. This is my first actual PCB :P
As for the layout. Ground is actually a plane on both sides of the PCB. Everything...
Thanks for the schematic! From my understanding, both designs should be functionally the same. Tomorrow, I'll pull out the oscilloscope and check and see if I can find anything obvious there. If not, I'll swap the transistor and see if that makes any difference.
I don't believe the resistor to...
Maybe somebody here can give me a hand? The only issue I have had is with the soft power circuit. It looks like this:
This is probably something stupid simple. So far, I have tested with the following:
2 assembled PCBs
Performa 636 Motherboard/PowerMac 6200 Motherboard...
I am currently using a picoPSU-160. It works nicely. It 'should' work with a picoPSU-120 however there is currently a compatibility problem that I am trying to work out.
There is also the issue of the power supply mounting. The Q630 chassis uses the power supply for structural reinforcement...
Hi All!
I just noticed a link to this thread from Adrian's video.
As it turns out, I was actually working on such a thing a few weeks ago. Attached is a picture of it.
I've included an optional 3.3V power rail (for 3.3V boards) and optional -12V power (for power supplies that don't...
