Original Soemtron factory test equipment
The basic 8601a was used in the factory on the Soemtron EFA 382/3/5 Electronic Billing machines and the ETR22 calculators, with overlay panels to customise the display for each model under test. It's not known if there were custominterface cables. The same equipment was also used for field service engineers, as our machine has a custom leather (?) carry case with several overlay panels. There was also a miniature version of the 8601a called the MINITESTER.
