[Milsurplus] Unk circuit board from ?

[Hubert Miller]

Thanks, Gordon. I didn't find this myself.  I was curious enough that I thought I'd have to trace out the circuit, but this saves me that. 
I will donate this and some other boards to a "transistor collector".

>Hi Hue,
That is a G-Series Digital Circuit Module from Raytheon Computer. Catalog is here:

https://archive.org/details/TNM_G-Series_digital_circuit_modules_-_Raytheon_C_20180403_0001/mode/2up

That module is on page 28.

From the catalog, I guess these modules were designed to allow engineers to create and test out digital circuits quickly. The back of the catalog has breadboards, enclosures, power supplies, etc.
