I'm not certain as I never used one, but the VSV11/VS11 appears to be
primarily a (raster) frame buffer, but also has some display
processor capability. [Something we used in the Graphics Lab, but
never DEC, always third party frame buffers, and E&S display
processors.] Therefore there may not be a lot of DEC software to
take advantage of the device. There was a DEC driver for RSX-11M as
a product. There may be other COTS or locally written software that
uses it to advantage.
Looks like XXDP will at least check out the device. See CVVSA and
perhaps other XXDP routines.
Might try "GT ON" under RT-11 to see what happens. The docs say it
can emulate a VT11. If that's successful, you should be able to play
Lunar Lander.
Good luck; sounds like fun.

I don't have much to say I'm afraid. A friend notified me of a 11/73 at
his workplace and I went and had a look. I didn't expect much but was
surprised to find a fully loaded BA11 box and a full expansion box. In
the expansion box was a VSV11 with two memory cards. The system seems to
check out ok, but we haven't booted anything yet.
I'm curious though, what software took advantage of the VSV11? Argh.. I'm slipping far from topic here,
maybe I should write something
about the PDP-11/73 with VSV11 videocard I got to play with yesterday.
That would be actually refreshingly on topic ;-)
