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.
