Somewhere I have a "tape only" SCSI controller with complete
documentation.  For normal operation, it just emulates TMSCP,
but it also has a SCSI pass through programming interface.
At some point I tried writing a driver, but could never
get a response from the card.
Some day I'll dig it up and work on it some more...

I wonder if other {T}MSCP <-> SCSI controllers have a
similar capability?
