It appears to be a complete multichannel analyzer for
nuclear detectors. It takes an analog signal, detects the
peak value, runs that through an ADC and then increments a
memory location related to the ADC value, thus
producing a histogram of pulse heights. These are
equivalent to particle or Gamma ray energy. Then, the
computer software can analyze it and tell you what
isotope(s) produced that pattern. This was a late 70's to
early 80's system that was in use at a number of physics
labs and related research areas.
