Product code: Mystery vintage outlet computer cards gold Trace vacuum tube aluminum handles circuit
Own an incredible piece of computer history. These are pluggable vacuum tube modules for a mid-1950s computer! Two of them are designed to hold a vacuum tube and they're made with high-end machined aluminum handles and top pieces. Each one is screwed to a circuit board with all gold traces on green circuit board composite. There seem to be diodes, resistors, and capacitors on the circuit boards. They are each stamped with a particular number. They also have the codes CM-110 f, cm-140-c, CM-119. These are exactly the same pieces in the collection of the Computer outlet History Museum: https://www.computerhistory.org/collections/catalog/102640052. And also ~102641951. These are from the estate of a Philco electrical engineer. Philco was instrumental in developing the transistors first used in computers! Through my research, I have concluded that these are similar to vacuum tube logic modules found in Burroughs B205, ERA 1101, 1102, and UNIVAC 1103, Whirlwind.
