On the other hand, there's something to be said for taking a beat-up piece of
trash and getting it going again.
... go for that post-apocalypse look.
You mention that there is no memory, however if you look at the brochure/advert:

the circuit board complement (4 or 5 boards) looks similar to what is in your photo:

And the text at the bottom of the brochure/advert of the fast model:
http://www.simulogics.com/nostalgia/DCC/DCC112H_01.jpg
says semiconductor memory was used in that model.
Could it be there was semicon memory there instead of core?
Maybe there is a chance (?) it is a 'complete' processor.
(I like the tube/valve tossed into the bottom of one of them.)

It's a 12-bit machine, but big odd non-DEC-looking boards. It's
7400 TTL, with 1974 and 1973 dated-coded chips.
Both machines are ruined. Sacked in mud, probably for a decade.
Little rust though, looks like damp, then blown-in dust or silt.
Boards are possibly recoverable.
No memory or any accessories within 10 feet, I think they were
buried under junk and just unearthed (Don is going through the
yard).
The switch register is 12 bits, and a LINK light, so I assume
it's a pdp8 clone. Could be wrong of course.
