Can any one tell me what DSSI is and if there exists
a DSSI-controller for
a uVAX II ?
It's a DEC-proprietary drive interface. Reportedly electrically similar
to SCSI, but definitely *NOT* compatible. The protocol is apparently
almost the same as is used on CI to talk to HSC controllers.
The Qbus host interface is the KFQSA, M7769. Not especially rare, but
I haven't been tripping over them lately either. I have a spare that
I could sell if you get desperate for one.
