Complementing Norbert Kehrer's talk from June on static conversions and emulation in JS, a classic emulation topic: "Spacewar!", the very first video game (1962) for the DEC PDP-1, the "first toy computer" (© J.M. Graetz). – Probably, it doesn't become more classic than that. Especially about visual emulation and JS surprises (A bit of computer history may not be totally excluded).
This talk was held by Norbert Landsteiner at the monthly ViennaJS meetup in Vienna.
