I'm working on a project in my job, but being only a student in CE and Comp. Sci. I'm limited in knowledge. I'm looking for a way to communicate with an arcade game, with a standard PS/2 Keyboard. Eliminating the standard joystick and buttons and using a keyboard instead. What would be the best and efficient way into tapping into PS/2 data and clock signals and get them to act as a switch? Where " W " key is UP, S is down, etc etc. Basically I'm looking for the complete opposite of a Keyboard Encoder, which I imagine would be a Decoder. I've seen some Atmel chips that will do the job but I'm just not sure if theres another more easier way? As of now, what I do is rip the keyboard open and rewire it. This method is time consuming and I know theres something like a Decoder where the ASCII signals can be tapped into with much ease, and I can reprogram them to have them act as switches.. Any insight?
