Hey Gang, so here's a IMHO tough nut to crack...
Just got two SE 1/20. Cleaned them etc. and both boot fine off their screaming original 20MB HDDs.
What puzzles me is that both(!) refrain to accept every floppy-disk being fed to them... either instantly ejecting or offering to format them. Yes, the disks work fine on other Macs.
Trying to format a fresh 1.4M or 800k disk results in happy grinding but ends with an Error.
So out went the original MP-F75W-01G, complete clean'n'grease, positively checked with another Mac and back into the SE. No change.
Ok, got a MP-F75W-12G from 'the stack(tm)'... no different.
So these are the ROMs:
...and the PCB printing:
Any ideas? As I can't add any software to them, I'm not able to check the ROM id if it's actually an FDHD one (ROM ID: $037A)...
