Smells of (early) 1960s transistorized.
No helpful marking apart from
* "GATE JJ01" on SIDE A. (components).
* "C NT OL DATA" on side B (solder traces).
Big transistors are Motorola "180376008". Also, any ideas what the "246
636
B" boxes are, they have four legs?
A curse on TinyURL and praise to Camiel Vanderhoven.

side. I suspect CDC manufactured these for LEC. CDC could have been secondary contractor
for Lockhead on a government project.
