Quoted from ronaldvg:I was not talking about the coding, that is quite simple. What I meant was: how does the machine know what award is showing on the playfield. there has to be something in the hardware that reports the position of the discs, otherwise it cannot be coded at all.
edit: I went back and re-read your post as I did read it and I think we are talking about the same thing. But I did not mean the coding, but the physical way that the code knows what is happening on the playfield.
Couldn't each disk be driven by stepper motors...similar to how slot machines operate?
