Interesting... appears to be some kind of temperature controller... I found
a NASA technical report that mentions it and discusses some of the specs;
apparently it's based on the Signetics 2650A at 1.25 MHz and according to
the spec sheet, it's designed to use standard 4-20 mA interface to
instruments, etc.

Maybe worth it if someone's looking to hunt down some 2650A CPUs and maybe
some support chips for a vintage SBC project.
