I have been using a CMD technology (
http://www.cmd.com) CQD-2xx/TM
SCSI <--> QBUS controller in my microvax II, and have been quite
happy with it. It emulates MSCP and TMSCP, so no additional drivers
are required. Unfortunately, at $800, it is about $800 more than I
paid for the computer (sigh).
The only down side is, Ultrix 3.1 won't work with a drive with more
than 1.2Gb or so, but with some partition magic it works just fine.
Also it will talk to my Archive Python DAT tape drive.
On the other hand, I have been pondering the development of a ATA
drive controller that emulates MSCP (and possibly TMSCP). There
is a DEC document that describes MSCP (I don't have the part number
handy). Does anyone have a copy they would give/sell/load to me?
Thanks,
clint
