Home / Hardware - Atari to CoCo Joystick Adapter
Atari/Commodore joystick adapter
Here's a fun and easy project I've loved using with my CoCo. This adapter was designed to interface an Atari(or C64) style joystick to you CoCo. This is great for games like Zaxxon or Ghana Bwana, where analog controllers are sometimes too sensitive. I left the Atari connector out of the schematic so you can also easily convert a dusty PC gamepad or nearly any "digital" (meaning on/off switches as opposed to analog 0-5v) joystick. I attached an Atari joystick cable to an old Nintendo gamepad, plugged into this circuit to plug into my CoCo. Talk about a Frankenstein setup!
Problems: pressing together up and down or left and right (it is unlikely but can happen) would cortocircito, damaging the circuit or power can of coconut.
Also the two buttons are not connected in the common direction switch, forcing you to do this montage, just inside the joystick and having to do, obligatorily, modifications to the plate of the joystick.
This circuit solves both problems the other (the short-circuit signals and the lack of a common signal for shooting and direction), and also makes the common signals Atari joystick is GND instead of +5 V. This means that the joysticks which have circuitry-trigger function.
