This is a DEC, DCJ11 processor bus emulation system built in DOS/Borland Pascal that allows in circuit and functional test the entire processor system (memory, boot EPROMS, QSLU, LTC, DRV11 parallel I/O, machine I/O and jumper settings by removing the DCJ11 processor and plugging in our 60 pin emulation pod. I designed and wrote this software in 1996 for my BSEE undergrad sr. project . We fired this up today in order to test a legacy board. 

Testing a three phase brushless, variable reluctance motor (VRM) driver 🤓. Checking for phase shift,  and pulse width modulation (PWM).
