[Simh] EXT : VAX SDL support?

[Ray Jewhurst]

I've seen references to VAXwindows.  I know it predates VMS 5 but I am not
sure if it was a layered product or not. There is also a very primitive
window system for P/OS on the DECPro called Synergy  (which I would love to
find documentation for) that you could control with either the keyboard or
the digitizer. I comes with the P/OS package for xhomer but I have yet to
get it to  work with the mouse-emulated digitizer.

The eary VAXstations could also run VAXwindows, which predates DECwindows
and isn't based on X.  I used it at one time.  It was ok, but rather slow.
It's not a client-server system as X is.  I wonder if any copies of the
software still exist.
