2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.

Home / Hardware - Atari to CoCo 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.
Use exactly the same components, and with the same values??, the original circuit. It is the provision which changes.
