Last week, we disassembled a really gross Apple II plus ( Apple ][+ ):

I've cleaned it up this week, so let's reassemble it and see if it still works. Also, we need to get the Rifa out of that power supply.

Also, I got an extremely nasty Power Macintosh 7100 from @GutBombTech . I cleaned up the logic board this week, but the PSU is still a mess. There will be nasty pictures of this thing and more nastiness as we dig into the power supply... which looks really similar to a Macintosh IIci power supply... which has 6 Rifas.

The power supply wound up being an Astec AA16870. I made a capacitor map for it here:

My Single Board 486 hates the PicoGUS. Is it because my soldering is bad? Also Apple IIplus resto!

Can we get this battery bombed Macintosh IIvx with ultra rare DayStar PowerPC upgrade card working?
