Ultrix would be wonderful, except that it doesnt run on the VLC. 
The last VAXstation Ultrix ran on was the 3100/[34]8 (KA42).

it should be (IIRC) 1280x1024 at either 60 or 66 Hz. 
A good multisync (if it can take SOG) will work.

The VLC is certainly a cute little box, and it does take ordinary 72-pin 
parity memory, which is nice, but alas, nobody has any dcumentation for 
these machines! (does anybody??? ive been tryign to find something!
woudl anyone be willing to split the cost of buying technical manuals 
from DECPAQ with me? theyre _expensive_)
