The onboard graphics however seemed to be bad. With a pattern that changed if I swapped the VRAM modules around. The ICs on there are ordinary DRAM.

After trying a different video cable it works though. Except the resolution is so weird that even the LCD cannot properly display it, without messing with every setting of that monitor. My CRT is still hopelessly confused. Ahhh, Apple

That's pretty cool. Too bad that the mechanism in the other drive is jammed.

Wrapping up the IIvx with the working floppy drive.

Today on the bench: heating blankets.

These things are designed to fail after a while. The driver units are super simple.
Failure points here: the caps went bad (they serve as a capacitive dropper to provide the supply for the microcontroller). But also the 10 Ohm resistor burnt itself halfway open and took the thermal fuse next to it with it. I shorted that as a test until I can get a replacement.

The other heating blanket had a mechanical issue.
But the driver had already killed its dropper capacitor a while ago. This is a replacement. Those To-92 parts are the thyristors that switch the mains voltage through to the heating elements.

Newest acquisition: an IBM PS/2 Model 30. The 8086 variant.
This is one of those low end PS/2s that came with ISA instead of MCA.

The hard drive is a full height 3.5" affair, probably ESDI. But with this weird card edge connector. This is probably the only computer line that ever used these. So, there won't be a replacement for it.
