It is, however, also possible to install an 800K drive into a 128K or a
512K machine without upgrading the logic board, if you use the later
version of the 800K drives. Larry Pina covers this in _Macintosh
Repair and Upgrade Secrets_, p. 192:
"Older models of the 800K drive won't boot unless 128K ROMs are
installed. Newer models boot fine with any version of the ROMs. You can
even install an 800K drive (part # 661-0345) in a 128K Mac and it'll
work fine. You'll have twice as much MFS disk storage as before, ..."
all. It was mentioned I needed a "newer" 800k drive. If the 800k drives in
an SE aren't the newest ones, what ones *are* and where would I find one?
Phil's list of part numbers
http://www.mandrake.demon.co.uk/Apple/part_nos.txt
gives some more information but no dates:
661-0305 Disk Drive 800K -Black Serial # (MFD-51W) 661-0345 Disk Drive 800K -Red Serial # (MFD-51W-03)
So the number on the side of the actual drive should be MFD-51W-03 [basically anything higher than the original MFD-51W ...]
Below, Phil seems to indicate that the platinum A9M0106 external 800K floppy drives all contain MFD-51W-03 drives:
M0131 Mac 800K Drive -Beige 661-0305 Disk Drive 800K -Black Serial # (MFD-51W) A9M0106 Apple 3.5 Drive IIgs, IIc+, Mac 661-0345 Disk Drive 800K -Red Serial # (MFD-51W-03)
I have a drive with a red-number sticker placed over a black-number label that was presumably upgraded in the factory, before being sold. I'm not sure where it came from--either a Mac Plus or an M0131 drive.
Best of luck, Eric
