Description

This logic module belongs to the DYSEAC computer (Second Standards Electronic Automation Computer). It is built on a long metal chassis like a box. The top of the chassis has six 7-pin miniature tube sockets and 4 octal tube sockets. Some of the octal sockets have plug ins with glass encapsulated diodes soldered to them. The bottom of the chassis has 2 large 12 blade connectors and 2 coaxial connectors. Inside the box numerous resistors and capacitors are wired to the various sockets, along with several chassis-length bus-looking wires.
