The encoder in my Apple /// failed and I didn’t want to scavenge another Apple /// to get one. So designed a replacement. After several revisions and help from some awesome collaborators, we come to the final version – a universal replacement for the AY-5-3600-PRO that works in basically everything.
Includes the factory keymapping as used in the Apple //e and Apple //c, plus many other vintage computers. It also includes the custom mapping used by the Apple /// and Apple /// Plus. One encoder supports them all. Need an off-the-shelf solution for your hobbyist electronics project? This will fit the bill!
Designed by Joe Strosnider, with testing by Petar Puskarich, all key functions have been meticulously mapped, traced and tested. This encoder successfully passes the Apple /// Dealer Diagnostics, Apple /// Plus Dealer Diagnostics and Apple //e Diagnostics 2.1.
Each unit lovingly assembled by hand in Ohio. ♥
