All,
I got my Mac working again by refurbishing the Analog board after checking
voltages and discovering I was running a whopping 10V on the 12V rail.
Everything is running in spec, Floppy drive auto inject\eject works as
expected but it cannot read or format disks. It fails format on Verifying.
It failed on verification. Unfortunately this project is on hold until
later since my board has finally suffered the checkerboard boot pattern.
I'll need to do a recap on it before I investigate the floppy drive further.

Thanks for those tips. It does accept a floppy and attempts to read it, but
all attempts to do anything to the disc fail. I haven't had a chance to
floppy-ectomy the unit yet to inspect it up close but we'll see what my
lunch break at work looks like today. I've verified the Disc is OK in the
only

I should still have some new-old-stock floppy drives, I'll have to
check and get back to you.

Incidentally, the Classic came with System 6.0.3 in ROM. You should be able to
boot into it by holding Cmd-Opt-X-O at the chime. From there, you can use the
serial ports and
