I have bought a Sun DWIS/S card to drop in an old SPARCstation and
hopefully talk to some differential SCSI drives. What I can't
confirm is which kind of differential SCSI the card supports. I'm
guessing that the absense of any information means that it's HVD
(which is not what I need right now).
The SunSolve page on the controller is at:
http://sunsolve.sun.com/handbook_pub/Devices/SCSI/SCSI_DWIS_S.html
...to remove any ambiguity about what card I have coming.
Thanks for any illumination,
