Funny you mention that...

“ESP8266
Application Note
Firmware Download Protocol
Version 1.1
Copyright (C) 2017”

And, the ESP’s have over-the-air updates. ZiModem does it with “AT&U” but we have to at least get an initial version there.

If the image is too large to fit on a .DSK image (I want real CoCos to be able to do this, even without a hard drive or CoCoSDC), then we can make a tiny one that knows just how to retrieve it over your WiFi network.
