> Interesting... rather than being an interactive circuit simulator as I expected, this is an engine for emulating circuits composed of 7400-series logic chips, 555 timers, etc., defined at compile time. It includes definitions for several games built this way, such as Pong. Cool project, but not very well described.

It sounds like an interesting project.
