Modify PSX Controller for Vectrex Games Console

Step 6Finally...

Finally...
Once all eight wires have been soldered ti the respective pads and everything looks okay, use a multimeter to test all the pins for continuity. Make sure none of the rails are shorted together.

If possible connect a 10-15V supply between pins 7 and 9 (pin 9 is negative!) and check the voltages present on pins 5 and 6 as you move the joystick around or push the D-pad.

Check the voltage on each of pins 1 to 4 is around 5V above pin 9 when the respective button is pressed. (When each button is released, its pin just floats.)

When you are satisfied all is correct, plug into your Vectrex and enjoy. I found the PSX controller to be much easier and more confortable to use than the original controller, allowing far more rapid firing. I easily got to the end of MineStorm the first time I tried it out.
