This is a trophy war in Ukraine.
Multi-channel military electronic control/signal processing board.
What we see here is a Soviet electronic board for military or aviation use, assembled using 564-series CMOS microcircuits in military-grade metal-ceramic housings. These boards were used in control systems, automation systems, and logic signal processing. This is not consumer electronics, but an example of reliable Soviet engineering, designed to withstand vibration, temperature fluctuations, and long-term operation.
Purpose (most likely):
signal processing unit
generation of control pulses
intermediate module in:
aviation equipment
military measuring equipment
radar or navigation systems
automated control/protection systems.
