Thanks for the pointers to get started Stiletto - that was *very* helpful.
A couple of my favorite games use discrete logic so I've long looked for signs of progress in this area. Pullmoll, are you documenting the schematics in a diagram editor (Dia perhaps?), or are you defining them in XML directly? Nevermind - can see one of the screenshots shows ExpressPCB.
Your progress is absolutely *great* and I hope your work can be used as a base to document/simulate many more of these games in the future
