SCSI-2 compliant drives are backwards compatible with SCSI-1. I've heard
that the Ramfast doesn't fully implement the SCSI 1 spec (something
about bus arbitration). A shame, it's a rather nice card. Quantumn
Fireballs don't work with the Ramfast.

Odd, I've found the high speed SCSI card to be fairly compatible if a
bit slow. Are you providing TP (termination power) to the SCSI bus? The
Ramfast features TP on the card but it's a special mod for the high
speed SCSI. You can provide TP to a high speed SCSI system by placing a
harddisk with TP on the bus.

I don't know. I normally use ADU or the Chinook SCSI utilities.
