The ST-01 is a dumb SCSI host adapter that requires the software to do
everything for the SCSI bus. Can you say overhead! SCO has support for
the AHA-154[02][A] SCSI host adapters. It can be gotten at Anthem, Wyle Labs
and Hamilton Avnet. Street prices are about $279.00. The ST-01 is only
intended for the MS-DOS market.
Somewhere, I have already posted my philosophy about cheap SCSI host adapters
but here it is again.
A good RLL controller/drive combination is better that a cheap SCSI adapter/
drive combination. I know this is cliche, but with SCSI, you really get what
you pay for in terms of performance and reliability. I hope this helps.
