I found a partial spec. It has this to say:
The second port is the SCSI/DSSI bus
and the
required
control signals. The outputs from the
SII are designed
to
interface directly with the NCR 8310
Receiver/Driver chip
with
no glue elements. The SII will generate and
check parity
and
support both the initiator and target roles.
Things may have changed by the time stuff shipped, and you certainly
cannot put a SCSI drive on a DSSI bus (or vice versa) but clearly the
two busses are fairly close at some level.
