Sorry for the delay here is a basic photo that shows my recreation of the IIGS tape in port. The circuitry is based on an LM741 opamp. This is a recreation of the cassette in circuitry found on the Apple IIs. I currently getting +5v and GND from the joystick port and I am getting the -5v from the power supply plug. Ultimately I may create a card to make it easier to get the -5V this would allow me to add a cassette out functionality as well. For the sake of simplicity I may just add the circuitry to create the -5V using the +5v and GND found on the joystick port, which would allow me to add the cassette-in port without taking away any slots.
