Some Test Equipment

 

Board Compatator showing the Program Board which defines the inputs and output pins

Board Comparator, which compares a good and bad board. Signals are sent to both boards on the input pins, and the comparator monitors the output pins. As soon as the outputs differ, the machine will halt, indicating which output pin failed. The operator now traces the fault using a logic probe and relavent schematic.

Tode Tester which uses a program on punched tape to test the board

Assortment of test units to test specific boards

Printer Hammer Module Tester. Tests the Hammer Modules dynamically to set them to specification

In Circuit Chip Comparator. Compares chips on a good and bad board using an Oscilloscope to display the Lissajous Pattern
