OK I have one so I know what it is. FD55BVR, care
to guess? Also a
FD55BFR?
Let's see, the BV is a 360K unit with head-load solenoid. The BF has me
stumped. The F would indicate a 720K drive, but if that were so, the B
wouldn't be part of it. FWIW, the "R" is a delimiter and ends the
capacity/special feature field. What follows next is a number, such as
200, that signifies revision, bezel color, etc. A final "U" means the
drive is UL approved.
Cheers,

Thanks for the lesson! My info on the AV and BV drives only notes a
head-load solenoid, not a door lock. If the BF is only the reversed drive,
I probably could have discovered this myself if I had taken the time to
check my own stock--I beleive that I've got one somewhere.
However, according to my Teac product information, the bezel color is NOT
part of the part number before the "R"--that's in the part of whatever
follows the "R".
I also discovered that yes, indeed, Teac made 5.25" SCSI floppy drives and
was sourcing them as late as the mid 1990's. I also have some information
regarding initialization strings on the Teac SCSI floppies.
Cheers,
Chuck
