This  guide  describes  the  organization and  use of the  IBM  Basic  Counter 

Unit.  The  IBM  Basic  Counter  Unit  monitors  the  various  activities  of  a 

system  and  provides  data  for analyzing a  system's performance.  Among 
the systems that can  be monitored  are:

IBM  System/360
IBM  1800  Data  Acquisition and  Control  System 
IBM  1130 Computing System

IBM  IN T E R N A L   U SE  O N L Y
