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.
