I was wondering after speaking to my mate who is making some front end software for me... If he could create a manager menu in which you could refill the hoppers, empty them, see the coins in, coins out etc. I'm not sure if this has been done already so if someone knows, let me know and how it was achievable, obviously he was asking what hardware was used, i.e. pac drives (which are next on my order list) and he asked what type of signal was received etc. to be able to convert it to data. He knows what he's talking about lol.
