Verifying Program Chips for Ms Pacman
  Computer Aided Testing System
 
     
     
 
        The following image shows the one of the test screens available while testing the program chips on a Pacman PCB. All program revisions are supported, as well as all EPROM types. Additional screens are available to test and verify the program chips which exist on the daughter board, when testing Ms Pacman-type program versions. The multiple game conversion is also supported.
 
Selecting program chip 6F M932B on a Ms Pacman (or Pacman) for test:
 
Address 1000-1FFF Pass        
 
This screen shows the master data reference file, for which the  readback data from the program chip at 6F will be compared against. By default, unless there is an error, the "Pass" indicator shows. Upon detecting any errors, the "Error" indicator would display, and error analysis will begin.
All Pacman and Ms Pacman PCB's submitted for repair to GLS1 Electronics will undergo these tests.
