This thing is already a pain in the neck to work on. The board is held on by this screw which cannot be removed without also removing the plastic back
Alright, so the front and the white half of the drive bay is one plastic piece.
And underneath are plastic clips (red) as well as metal rods (blue). Once this thing snaps into place it's near impossible to take it apart again non destructively. Oh and the PSU is riveted in place.
What an utter pain in the neck this is.
At least I got the board out.
This is actually an 8086 not an 8088. Huh. Kinda cool.

Fuck whatever this thing is. All my homies use CR2032.
Despite the absolutely proprietary nature of the PS/2 line, internally the floppy drives look fairly ordinary. Aside from the connector and form factor. They even have a drive ID jumper. What use is that in a PC compatible?
And then I wonder why there is always so much dust in my apartment.
This was loose inside. Any idea where it goes?
Nvm
Drive is clean again and so is the board. I replaced what tantalums I had on hand. The last one on the board I can do with the board in the case.

Tomorrow I'll clean the case and then let's hope everything works.

Oh and the PSU wasn't riveted in after all, just stubborn.
I gave the power supply innards a visual inspection, adjusted the voltages, put it back together and I get ... Nothing. Black screen and two beeps.

I created a reference diskette (the drive is 720k only btw), but it only briefly spins up. A friend with the same drive said the electrolytics on the spindle motor pcb were leaking on his. So I guess that's an issue on mine too.
Yeaaah... Already produced that typical fish smell when desoldering
