Hiya,
That could very well be a VAXstation-3. If it was
sold as a
VAXstation-II and upgraded with a KA650 CPU and MS650 memory module(s),
that'd be an appropriate designation.
I had one just like this back in the day with full graphics , mouse etc
that I used as a workstation. I upgraded it from MV-11 to MV-III in box
with the above kit.
Nice versatile units and I hope they go somewhere they can be used.
