Hi guys,
   Just got some hardware up & running last week have been meaning to 
   post the info.. I'm running it on a PDP-11/44 but can't see any reason 
   it wouldn't work in a vax.
   The boards have VT30H printed on them and connect to 
   a fairly std looking RGB monitor. Each monitor needs a 2 board set
   I think these things were reasonably common in industrial control systems.
   I'm still not sure how to make use of it properly yet, the RSX driver
   is loaded & i've got an application that draws a picture on the screen.
   Looks like 16 colours, and reasonable resolution.  

   The machine it came in had 2 card sets for more than one monitor in 
   the card cage. 

   4 cables for red-green-blue-sync

   It looks like you can connect a terminal device (software) to the 
   display driver and use it as a terminal in text mode as well but I 
   haven't figured out how to do that yet. (under RSX)

   I have enough bits & pieces to build up 2 systems so getting the second 
   machine up & running with unix is the next project. 

Cheers,
     Steve
