After a trip down to Asian Pearl, Al and I took a
trip down to the local recycle place. He spotted an
Apple 3.5 inch External drive, the 800k variety we
were discussing recently on the list. He wasn't
interested, so I snagged it, and it appears to be
working fine on the Mac IIci, although I wasn't
sure at first, as it took me a while to find any
800k disks.
Outside, I found an IBM Type 9331 011 8 inch external
floppy drive, a nice black enclosure with the IBM logo
in the oval badge set at 45 degrees, like the PS/2 line
logos were. The interface connector on the rear has 37
pins and so I'm hoping it's the same as the interface
on the old IBM floppy interfaces that had a 37-pin
external connector.
Anyone know what these drives were used with, and will
I luck out on the interface? It needs cleaning...
Also, an IDE removable harddrive carry case & two mounting
frames, so I can start carrying serious storage two & fro
the orifice, er, office.
No blinkenlights, although the poprietor indicated he'd
dumped a bunch of old stuff six months ago. Oh well, the
way he does this is he leaves a pallet out front for people
to stack stuff on. I'll start checking more often.
Anyway, total damage for the above: eight bucks; five for
the Apple drive, two for the IBM floppy, and 1 for the IDE
shuttles.

I got a type 9331 model 011 with an AS/400 system... I think. When I get
home, I'll look at it (and its //manual// :) again.
Ciao,
Chris.
