In Reply to: How to wire HAPP Perfect 360 Joystick?? posted by Marlin Liew on August 26, 1999 at 17:01:32:
: I'm having trouble figuring out how to wire up my
: HAPP Perfect 360 Joystick to use in my arcade
: controller for my PC.
: Since it is controlled via optical sensors rather
: than microswitches, it only contains a single pin
: for the U/D/L/R directions, plus a pin for +5V and
: a ground pin. My question is, how do I wire the
: single pins to my keyboard matrix? Do I just solder
: both the + and - wires to the same pin?
I don't know exactly how the Perfect 360 sticks operate, but with only one lead per direction you'll end up seeing the individual leads go 'active' for their respective directions. This 'active' signal will either be high (~5 volts) or low (~0 volts). The JAMMA standard is for the leads to be pulled low, so I'd guess you'll normally see ~5 volts on each lead and then ~0 volts to indicate the direction. You'll need to use these active signals to drive a switch that will complete a circuit between two of your keyboard decoder's contacts. Go to the PC2JAMMA page and look through the plans. You'll find the circuit you need there (for active low). If the 360 provides a high active signal you can use the same circuit but leave out the inverter (7404).
