maybe you can use one of those WiFi-enabled ESP32 things for yet another emulator
I've actually been thinking about trying this for a couple of months! I bet it could make my emulator a little cheaper since an ESP32 costs around $5 less than an Arduino Mega. Also, I could probably get rid of the LS280 and do parity generation right on the ESP32 itself since it's way faster than an Arduino. Due to the ommission of the LS280 and the small size of the ESP32, I could probably make the whole thing a good bit smaller as well while still using only through-hole parts, which was a major goal of the ArduinoFile project. And plus, as you mentioned, the WiFi functionality could make it really easy to update the Lisa's clock to the current time!
