IoT and the Apple // line don't sound like something that would be compatible in any way. Nathanial Hendler thought to change just that. 

His Apple2Idiot board is actually a simple idea. Take a dual-ported RAM, an ESP32, put both on an expansion card and off you go. ⚡️

The Apple then simply writes and reads to the RAM and the ESP32 does whatever it likes with the contents. Kind of like memory-based IO with total freedom to do whatever you want with it. For example, sending a Slack message, retrieving data from HTTP-based API's, or doing all the other fun things an ESP32 should be able to get up to.

Nathanials GitHub repo comes with a number of examples, and you can use those to for your own experiments. A simple and ingenious idea. The only question is where to get dual-ported RAM today? 🤔
