As the weekend progressed, I kept digging. Under a PDP-8/L I found an MM-11
box with five MM-11 backplanes (for the 4K sets), a peripheral backplane
(KM-11?) a PSU, several UNIBUS jumpers, missing only the fans and bracket.
Presumably now, I could assemble several MM11 sets and test them from
some other PDP-11, say an 11/34, which happens to be nearby. Hopefully,
additional digging will uncover the 11/20 cpu chassis. I did locate the
box with the CPU boards and all the core drivers. The box had apparently
gotten wet and some of the cut leads on the back of the board have rusted
a little. I'll need to figure out how to get that stuff off before I power
anything up.
Another gem I thought I'd lost was my TVT-6 - a T.V. Typewriter I bought and
assembled as a kid with lots of intentions of doing something interesting with
it. I never even applied power. Looking back on the shape that board is in,
I must say that I've gotten *much* better at soldering. :-)
Perhaps I'll attach it to my SYM-1.
