need help with coin operated pc project
im currently in the stage of making a coin operated pc, i want to interface the coinslot using the parallel port. my problem now is that the coinslot gives a 12v 50ms pulse, which is the source of all my trouble because in order for it to be parallel port compatible it has to be converted into a TTL signal, can any one help me find a way in converting this signal into parallel port compatible.
i already have a software that pools the parallel port for a signal from the coinslot signal and unlock the pc when a signal has been detected.
any help will be greatly appreciated...
