Hey Birt!'s video: Build an Arduino based vintage SRAM tester for TRS-80 M100 open source

Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at https://www.pcbway.com/ 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.
