Upgrading VAX Unibus configurations?

» close window

The Question is:

 
I'm researching upgrading a VAX 11/780 running VMS version 4.7 to a new
system.  System is the host system for a flight simulator so uni-bus
required.  Any suggestions would be helpful.

The Answer is :

 
  You need to determine specifically why the Unibus is required, and then
  determine if there are any alternatively approaches.  For instance, the
  DR11-series interface (eg: DR780) is one of the more common interfaces
  for communications such as this, and there are various DR-compatible or
  DR-similar device controllers for various buses available (eg: DRB32 on
  BI, DRV11, DRQ3B, and DRQ11 on Q-bus).
 
  If you (still/must) require a Unibus, you will be limited to a VAX 6000
  or VAX 7000 series with a Unibus option (DWMUA-AA/AB) (as the newest VAX
  systems), and you will need to determine if the specific Unibus device
  driver(s) can be gotten to operate in this new environment.  Various of
  the older VAX 8000 series can also support Unibus.
