This page is a reference for basic retro-gaming and arcade related oscilloscope information. I’ve made some videos that should help both as a tutorial and reference…and some day I’d like to create written guides for people to have an easier time referencing the basics.
Videos are below and here’s some of the equipment I’ve been recommending:
