| Computers played a major role in the pre-shipment testing
of the System/7, checking for potential trouble during the assembly
process. At the IBM General Systems Division facility in Boca
Raton, Fla., a technician testing a System/7 feature module
(center foreground) -- one of up to 12 sub-units that formed
the computer’s basic building blocks -- uses an IBM
1130 computer and automatic system entry device (left background)
to enter test information from punched cards. This system was
linked to a nearby IBM
System/360 Model 40 which stored test programs and common
data used to verify module functions and diagnose failures.
A direct digital test module (right background) provided a communications
link between a test processor and a group of simulators (right
and left foreground). The input/output tester (right foreground)
generated simulated analog signals to check the computer’s
analog elements. The test station power system (left foreground)
generated operational power to the module under test and also
housed a System/7 processor unit to provide module interface
simulation. |
