We recently installed another Wollongong Group WIN/VX TCP/IP system
on the following machine

Vax 785
VMS 4.4
Win/VX 2.3 (Not using shared DEUNA driver)
One Unibus with
 DELUA
 UDA50
 DLP11 (printer controller)
 DMF32 (Emulex)
 DMF32 (Digital)
 TU80

We now can run the network or the TU80 tape but not both.  Until we start
the network, the tape unit works fine.  After we start the network, the network
works fine but any attempt to use the TU80 tape results in a 'FATAL DRIVE
ERROR'.  A look at the error log shows

 Status 888C  Non-recoverable
              Subsystem ready
              Non-existent memory

The non-existent memory means that the TU80 controller referenced some
memory not mapped by the Unibus MAP registers.  Other than that, I have
no idea what's going on here.  The DELUA is a new device but DEC
has run diagnostics on it and it does work.  We have similar installations
with TU81 tapes but they do not have the tape controller and the DELUA on
the same Unibus.

Has anyone seen a similar problem?  Does anyone have a similar configuration
using TWG WIN/VX that works?
