@Toxic_Flange you’re welcome, glad you got it figured out!

@paul Please consider ripping them and posting the files to archive.org before you do - they’ll be considered #retrocomputing soon (if not already). I just saw someone post looking for a good rip of Mac OS X 10.0 Server the other day!
@Toxic_Flange Disclaimer: I know nothing about Commodore PSUs. However, AC doesn’t need a ground for current to flow, it just needs the line wire and neutral wire. It looks like the AC is stepped down from wall voltage to 9V by a transformer. That being the case, I’m not surprised that the AC is working (assuming continuity on both AC pins), while the DC definitely won’t work if the ground connection is broken.
I can’t believe Apple’s update servers are still serving updates for Mac OS X 10.4 Tiger! I just did a clean install of 10.4.6 on an external FireWire hard drive and Software Update is installing 10.4.11. Mind boggling!
@presstype @xandra I’d definitely be interested in using this for a #retrocomputing website if you released it at some point! Looks great!
@SinclairSpeccy MAME can emulate a few different Mac systems these days, so you could use its debugging capabilities. You might also be able to run MacsBug in the emulated system on Mini vMac or Basilisk II, but I’m not sure.
@jonschwenn The FAT formatting with HDA files works well. exFAT is the recommended file system for the SD card, supposedly much faster. With HDA files you can have multiple SCSI “devices” on the same SD card. You’ll create an HDA file of the desired size (2 GB is a mostly safe default size), and on the Mac you’ll format that as a new HFS hard drive.
ZuluSCSI manual is here if you haven’t seen it: https://github.com/ZuluSCSI/ZuluSCSI-firmware/wiki/ZuluSCSI-Manual
A lot of the BlueSCSI documentation regarding image files is useful too.
@Screwtapello It’s probably (though I can’t say for sure) a RIFA capacitor. They’re infamous for blowing up now that they’re old. They were commonly used as AC filter capacitors in old power supplies, but they very commonly fail these days.
@ktemkin Which boards did you end up deciding on?
Looking forward to seeing what you come up with!
@tommythorn I like this YouTube video on cleaning and lubricating the floppy drives in classic Macs:
