     Do you have the VS100 interface board?   I saw one
on eBay a couple of 
months ago, and I slapped myself in the forehead really hard. ;)   I had 
a VS100 for many years, and gave it away around 1993 because I could 
never find the interface board for it.   When I saw that board hit eBay, 
I really wish I'd kept the VS100.. 
   Yep, hung on to the board. I actually had to be a detective to get the interface board
- when I bought the VS100 box and monitor, from Eli Hoffman, it didn't include the
board. I had to call them, see who sold the monitor and box to them, and then trace
through that organization to find the department and person who had surplused the original
system, and buy the board from him.

   Since these days, I have a lot more interest in RSX than VMS, and the VS100 never
worked past VMS 4.7 anyway, I'm hoping I run across a UNIBUS 11 some day and see if I
can write enough of a driver to get it to draw pictures. Since I have the VS100 sources,
it's registers are pretty well documented.
