The other mini I've gone down too deep a rathole on is the Pertec
Computer Corp XL40 (univac 1900) which was a third generation key-tape
system. Pertec bought Computer Machinery Corporation, who appears to
have made their own PDP-8 clone (Bob Rosenbloom has one)
http://www.dvq.com/oldcomp/photos2/1k/cmc3.jpg for the first generation,
then they used PDP-11's for the 1800, then microcoding
their own 16 bit computer for the XL/40. What I have been able to dig
up is under pertec/dataEntry. I'm still trying to figure out what the
instruction set actually was.

Dumps of the programmable parts on the CPU would be nice if anyone has one.
So this was interesting, another in the list of 60s/70s minis - hadn't heard of
it previously.
Are there any known customers/applications that used it?
Didn't think I've seen a blinken-light front panel with worse graphics design
however.
