NexGen: Hacking a Sitek X-35 Joystick.
Converting the Game Port to USB - Part 1
THE ANALYSIS:
- - Disassemble the unit, and give them a bath, but if your handles turned gummy, I used "Brake Clean" in the Red Can. You will need some elbow grease as well. The GamePort cable has these 15 wires:
- black, white, red, purple, pink, green, light green, yellow, brown-white, black-white, black (dull, thick), orange, gray, red-white, blue.
- - Identify the wires. You should ring them out with your DVM.
- There are three circuit boards inside.

The potentiometer for the main throttle has three wires: red, black, brown
There are what appear to be 4 cables coming out of the throttle:
black, brown, purple, red, orange, yellow
Here is the pinout for the 15 pin DA-15 connector (Game Port) of the X-35. This plug connects into the X-36 stick.

This is a work in progress, I will add to shortly.
Keep Tuned In, More to Come.
