The original PSU has the pinouts molded onto the bottom plate.

Holes carved into the ends of the project box with a Dremel.

I never was any good with project boxes.

Online with the original PSU!

Heat shrink tubing as an insulator.

Now to clean up the 1541 disk drive.

Top and bottom separated.

That's a hell of an RF shield.

RF shield and mainboard removed. The cardboard in the drive mechanism is supposed to protect the drive heads.

That transformer accounts for most of the mass of the disk drive and is the size of my fist.

And, of course, three of the four screws stripped when I tried to unlimber it.

20200508_153924.jpg

Hell with it. I don't really need to unbolt it.

The drive's mainboard. Commodore disk drives were microcomputers in their own right, with a 6502 CPU and 2 kilobytes of RAM. There are two RF shielded subsystems at the bottom left of the image, but I've no idea what they are.

Drive mechanisms were commodity devices back in the day. Manufacturers ordered the right ones they needed in bulk.

Ew?

All cleaned up. The alcohol's almost evaporated. Note the two really big capacitors at the rear of the board.

Yes, that is a spider web spun around the read/write head. Don't ask about the organic bits to either side. I don't want to hink about it.
