Teac made SCSI floppies which were used by SGI and others; one of my
Indigos has one, and a couple of friends have them too. The floppy is a
more-or-less standard FD-235, except that most have a motorised eject. The
SCSI card is an add-on, albeit a very compact one.
If you don't want the SCSI cards, I can use them :-)

Rumor has it that Pete Turnbull may have mentioned these words:

VAXStations use them, too -- it's basically a SCSI to MFM bridgeboard that
is really quite compatible -- when my floppy drive died on my SCSI-enabled
PeeCee, I snagged my spare VAX bridgeboard w/1.44 floppy, set the SCSI ID &
slid it onto the chain... worked flawlessly.
I doubt the bridgeboard would work for a 2.88Meg floppy, tho -- dunno if
the "BIOS" (for lack of a better term) supports that density as it didn't
exist until well after the board was built.
I wouldn't mind having a spare, either -- they're tough to find...

Hmmmm. I've got one of those I tried to test off an Adapted 1542CF
I got the board to respond to the controller's device polling, but I
didn't ever actually access the drive. I even tried loading the ASPI
Manager device driver, still to no avail. Perhaps I should mount a
different floppy drive to it and see if it was just a bad floppy? Had
a dip switch on it but with only three switches, I figured that was
probably just the ID select, and my ID was already set to be different
from the controller, so I didn't bother messing
with it.
How did your's act. Like a floppy or a removable media hard drive?
Were you able to boot from it?

That may explain some problems: The 1540, 1540A, and 1540B (and the
correspondong 1542 models and the EISA version (174X) where they existed)
were excellent devices - the CF had a well-deserved reputation of being
oversensitive about termination; this was especially true of the version
with the "SCSI-2" connector rather than the Centronics-type.

Hi Andy,
The 1542CF I was using to test with was the Centronics connector version,
but I was coming off the 50 pin header anyway. Do you think I should try
again with one of the BusLogics, or wait till I reconfigure one of my test
boxes to an Adaptec 2940AU ?
