  Actually, the SCSI version that SCO has is only available in OEM
quantities (Version 2.2.4).  A new version of 2.3 is expected that will
support SCSI drives, but right now, the only place that I know where
you can buy 2.2.4 is at Radio Shack.
  As far as experience with the SCSI stuff, we have been running the
following configuration without any problems and have experienced some
very nice gains in the system throughput as compared to ESDI drives.

Tandy 4000 16Mhz 80386
4MB Memory
17 Serial Ports
EGA Console
1) Quantum SCSI P80 Drive (80MB)
1) CDC SCSI Wren IV	  (344MB)
1) Cipher SCSI Tape Drive (150MB)

As a side note,... Neal Nelson tested this configuration and came up with
some interesting numbers.  On all disk related I/O, the system came up 83%
faster than a Compaq Deskpro 20 with a 130MB ESDI.
