OK, I've powered on both of the systems with the
PDP-11/73 processor boards
in it. I now know that they are apparently "SMS 1000" machines, but I've
been able to find nothing on it on the net, except for a web page that has
a picture of one in a 'tower' case

Mine is in a rack mount case though.
That is my machine that I rescued from a skip. Hence the loose side
panel caused by it being thrown into the skip.
I do have some manuals for it if you are interested.
