In this video we build an Arduino Mega based tester for TRS-80 M100 SRAM modules. We learn about the unusual SRAM modules the M100 used, a little about RAM testing and then we test some bad modules and attempt a repair.
While this tester was made for a specific purpose the ideas presented can be applied to testing other vintage ICs. The design is open source so download all the files and use it as a starting point for your own tester.
