The problem appears to have been a SCSI problem. The configuration is an
Asvr 1000a 4/266 , four internal RZ28 , CD , internal DAT (TLZ09) and an
external DAT TLZ09.
When I removed the external DAT and terminated the bus on the back of the
system, the internal DAT worked fine. The SCSI cable from the back of the
system to the external DAT was 1 meter long. From my old DEC field service
days, I seem to remember that there was a STRICT limit of 0.5 meters of
cable allowed on the back of the Avsr 1000.
Why it had worked under V3.2G - Who knows ? Luck I guess !!!!
