|After getting the trackball in I soldered 2 of the joysticks and 4 buttons to a joystick (15 pin) connector. Two joysticks were wired through resistors (to translate the switches to a quasi-analog state) and run into the PC joystick port. 50 ohms was used as the stick center and 0
and 100 ohms were used for the left/right and up/down extremes.
The 4-way joysticks and other buttons were wired into the keyboard encoder.
I'll post a photo of the schematic soon.
|What the hell is this??!!
I didn't get a shot of the innards before I disassembled it to put in my defender cabinet. This is pretty much how it looked, minus the white labels. The wiring can get pretty messy but I didn't care much about that. I could have bundled wires together and used plastic ties to make it look nicer.
|In the end the control panel worked flawlessly! It was very responsive and quite realistic. Two player games worked perfect.
I didn't much like having to sit on the floor to use it but it's the next best thing to having a cabinet!
