I was looking around, and read where a user asked if the machine can be modded to take 1 token and register it as three. The answers were no, that it is a programmed function.

So, I have been looking for a good embedded programming task. This may fit the bill, not sure. I have tons of years programming computers, and wanted to try out embedded anyway (I am a system programmer at heart).

Any thoughts or suggestions on the internal logic of these boards?
