recent DEC/Digital add-in card SCSI adapters seems seem to go by the


where bus == P for PCI, T for TurboChannel, SA == SCSI adapter.

in this case, i'd guess that "it" == Intraserver Technology", which
seems to be the name of the company.  8-)

The other similarly-named one which stands out in my mind (because we
had a lot of them running around CMU) was the KZ[PT]SA, which were an
NCR siop of some type, sitting behind a '960 IIRC.

never could get docs on them...
