I have got a visitor: a dead CBM 4040 disk drive. The symptoms: all LEDs stuck on. No disk activity. This means the 6502 does not boot correctly.
First checks: voltages are correct, reset is working, clock is present.
Next up, OneROM with Piers Finlayson‘s IEEE diag ROM. However that also doesn’t want to boot.

Working on the CBM 4040... The first replacement drive has been cleaned, and the bearings have been lubricated as far as I can reach them.
