New subject: VT100s (was: Odd Q-Bus questions 18/22bit)

15 Aug 1998

...
 On a separate note, I ended up with 3 more VT100's
with this, and one of
them had a loose top, so I took a look inside, and noticed that it has
what looks to be a Q-Bus backplane.  What is the story here?  Can I put
some cards in here and have a working PDP-11?  (I know figure the odds)
I took a look through the VT100 tech manual I got today, but couldn't
find anything about the backplane. 
What you have there is a VT103... it has a 4x4 backplane (Q/Q) and a
more gutsy power supply than a standard VT100.  Yes, you can build
a working pdp-11 into it... One of my 'workhorse' machines when I was
in the RT-11 development group was a VT103 with an 11/73 (KDJ11-A),
256kb and a DSD880/20 controller.  I did lots of RT development and
testing on that machine...  I still have the machine in my office
in Nashua, even though I am doing Alpha work nowadays.
