I'm headed to Maker Faire in San Mateo, California (Friday, May 17 – Sunday, May 19) again this year, and one of the things I'm excited to check out is Matt Sengbusch's tiny arcade games that use the original boards and CRTs.
From Small Change Arcade: "Each game is meticulously scaled to match the original. Custom built in the Haight, San Francisco. All games run on original licensed circuit boards, no emulators or multi-game bootleg boards. No LCDs are used either. Each game has a custom built or difficult to source CRT monitor that accept proper 15khz RGB video signal."
