Anyone familiar with 1970s–80s military “8328 MATRIX” I/O boards?
circuit boards labeled “8328 MATRIX” and I’m trying to understand their role in early computing / embedded systems history.
Notable specs:
Built to MIL-STD-38510 standards with JM38510 qualified ICs (CGO house code)
Populated with AM26LS30 / AM26LS31 differential line drivers/receivers
Functions as a crosspoint / signal switching matrix
Includes configuration DIP switch, status LEDs, and robust military connectors
These appear to be high-reliability I/O or signal routing cards, likely from avionics, radar, or command/control systems of that era.
I’m curious how these kinds of hardware matrix switches fit into the broader history of computer architecture, real-time systems, or distributed I/O in military computing. Does anyone know the specific system these might belong to, or have insight into similar crosspoint matrix designs from that period?
Thanks for any information!
