TTL on an Apple IIe
This isn't really FRC related, but it is about robots, so I thought I would post it here. Open house is coming up at my school. I thought it would be interesting to make an automated greeter for the door to the tech room. I have a speaking chip that takes TTL serial input. I also have an old 1984 Apple IIe computer. It does not have a serial port, but it does have a 16 pin game port. The port has several pins that can be toggled easily from 0 to +5 volts with the processor being the only limit to the speed. I need to write a serial protocol for it. I know it can be done, but I am not sure where to start. Any suggestions?
