I think Linards has the key.  At some point in the drives' lives,
someone may have plugged them in in the off-by-one pin configuration
and blown the 74LS125.  Grab one or several of those chips, and open
'er up.  The chips are socketed, so it's dirt simple to swap them
out.  Boot noise but no action after that is typical of the chip
failure he mentioned.  Oh, and if that really is the problem - then
all the disks you've tried in the drive so far have been effectively
erased.

I don't know of a maintenance manual, but I did a video showing
disassembly of the old-style Disk II for drive head cleaning:
