This little bench-top tester was a real Mighty
Mouse© as the sixties ended and the seventies began. It became the
major tester of early semiconductor memories such as the 1103, the
2048, and the 4096. The test board plugged right into the front panel
and there was a lamp for every pin that switched on every time
the pin went high. ‘Girls’ on the line soon became proficient in
watching the lamps and could tell if the memory was going to fail
long before the tester itself knew. It could run at up to 5MHz,
testing walking ones, marching ones, galloping ones and butterfly
patterns. All for under $10,000.
