Yes, the BTN tape handler was written for the 3M MCD-40 which is a block
addressed device.  Sorta like a very slow disk.  It does *not* act like
a normal SCSI tape drive acts (or a normal SCSI disk, for that matter.)
The handler doesn't look like it would deal with a normal SCSI tape very
well either.  Just like the MCD-40, it doesn't know about variable
length records, file marks, logical EOT, etc.


NOTE:
All the folks with drives other than the MCD-40 who are having trouble
with BTN-Tape might want to try the tape handler by Markus Wandel (?)
It was posted a few days after BTN-Tape.  I haven't tried it, but it
looks like it was made for *real* SCSI tape drives (variable length
records, file marks, etc.)
