a driver for microport sys v/386 was posted to alt.sources on 17 Sep 90.
however, it's not possible to boot with it.

sure, but you won't get the real advantages that scsi devices offer.
i strongly recommend using host adapters that offer threaded/overlapping
operation, like the adaptec aha-154[02]A. its also very interesting
how the DTP controller would allow you to address seven devices on the
SCSI bus. as far as i know those registers have one bit for drive select?!
you also won't be able to use streamers, printers, nodems etc.

of course, if your unix doesn't support such host adapters you out of
luck. i wouldn't buy such one in the first place....

the poor machine...you realize that you'll use 5 year old technology in a
high tech machine??!!
