An HP-85TMmicrocomputer programmed in BASICTMwas interfaced to a PEI 2000TMsafety analyzer via an HP-6942ATMMultiprogrammer and appropriate interface cards. This configuration allows automated safety and performance testing as well as report generation. The system is operated by means of a menu displayed on a built-in CRT and the keyboard. Data are displayed and then stored on the built-in cassette unit. Additional testing features are easily added with minimal software development, since all programming is in BASIC and all interface drivers are part of the hardware.
