KEY800
ESP32-S2 USB-keyboard bridge for ABC80/ABC800, with WiFi, remote typing, and a web UI.
KEY800 is an ESP32-S2 USB-keyboard bridge for Luxor ABC800. A modern USB keyboard plugs into the board; firmware translates key events to the ABC keyboard interface.
It also has a small on-device web UI for remote typing, F-key macros, RGBtoHDMI helpers, WiFi, and OTA.
