VAX 11/785 as a workstation :-)

Last night I was browsing the UNIBUS/PDP-11 field guide on the Web before I went to sleep. Then I dreamed of a VAX 11/785 with an UNIBUS extension cabinet full of cards. Included was a 3, 4, 5, or so card-set that together comprises a video interface. Hook up a composite monitor or RGB monitor and there you have it: A VAX 11/785 as a workstation! Write a driver for X11R6 for it and off we go. Has anybody ever seen those UNIBUS video monitor adapter sets? I suppose they were meant for PDP-11s, but I think running them with a VAX would be way cooler. Might not be possible, and certainly would involve some serious fiddling. But in a machine that has 10 or more cards for just the CPU, a 4 board video adapter would be the appropriate thing, wouldn't it? :-) cheers, -Gunther
