About the only thing I can tell you on all of this is that SMS (though I
thought that was SanFrancisco Micro Systems) made PDP-11 clones. I've got
two SMS chassis' with DEC PDP-11/73 dual hieght CPU's and DEC 256KW RAM.
The Disk controller and Serial I/O is all off the Q-Bus on a SMS board.
>The backplane looks DECish to me - similar to what I've seen in a 11/44.
Is it Hex-Height? A Q-Bus Backplane would normally be Quad-Height, or
maybe dual, not Hex. Could be a rather interesting beast.

This sounds all very wierd, especially that 2 card CPU set. I'm wondering
what kind of CPU it even uses!
