Since you last asked the question I was able to find one of the following
DSSI cables: BC22Q-09.
It connects from the "old style" DSSI to the newer one. I don't believe
that
SCSI (as you have mentioned) can be addressed on a DSSI system
without active electronics. What you may be referring to is that some
DEC made some RF/RZ drives, which could speak both protocols.
I need a couple of cables to connect to a 4000, can
anyone help
You can enter "BC22Q" into the search-engines.
