Quoted from CavemanJoe:Okay, a four-player version is gonna cost a little more - we'll need a better MCU, with more memory and more input pins, and/or some sort of multiplexing arrangement. We'll also, probably, have to move to a four-row LCD, for best results. People who want a four-player version:
* If you had to choose one manufacturer for me to work on first, who'd it be? Gottlieb, Williams, Chicago Coin, someone else?
(I ask because the physical shape of the reel reader boards will have to be a bit different between manufacturers)
* How much - ballpark - would you be willing to pay, assuming I could get this up and running on four-player games?
Obviously Gottlieb.
Price is going to be a problem. Though some (like me) are willing to spend stupid money on EMs, there are plenty of more practical people who would not want a mod that costs half of what the machine itself cost them. I suggest that you figure what the price would be allowing for a decent profit and put it up here and see how many people are still interested. I would pay $150 for 4-player, 125 for 2-player and 100 for 1-player. Maybe more depending on what all is in the final package.
Great work by the way! I like the idea of going optical.
