Yep, they're close but not quite. Not sure if SASI supported ten-byte
commands either (probably not). 

To further muddy the waters, there seems to have been a time where SCSI
was replacing SASI, but the SCSI Common Command Set wasn't yet ratified
- so things existed that were for all intents and purposes SCSI, but
left out a few commands here and there (some of the OMTI tape
controllers I seem to remember are like this).

Hence the reason I'd quite like a simple paralle-port type interface
than going the internal ISA card route as I expect I'd find there are
always going to be a few exceptions to the norm here and there that'll
need to be worked around - and it'd be easier to do all the driving in
user-land on a PC than messing around with hacking device drivers at any
kind of OS level...
