Most Torch machines used an OMTI 5000 series board, I
think
This is a Xebec board, no identifying marks apart from 'Rev E04'
There's also something about reading the drive
geometry from
the first (zeroth?) sector of the drive, then sending some
commands to the OMTI board. I doubt that modern SCSI drives
will handle that correctly.
It sounds like it's the SCSI identify command. I remember using
a WD chipset board with an Amiga to run two 40MB ST506 drives
many years ago that would mostly work but would eventually fall
over if you tried the identify command too many times.
Writing raw data to a SCSI device is no problem so I may be able
to make a proper SCSI drive look right. Guess I'd beter dust off
the logic analyser sometime soon just in case it doesn't work.
Cheers,
Lee.
