6526esp32
An internal WiFi using ESP32 microcontroller for Commodore computers (C64, C128) with level translators to a parallel bus interface so it is addressable as a co-processor sharing $DD00 IO space. Capabilities will include sys/jmp calls to esp32 served code for a wide variety of applications via dynamic codepages. This is based on the work of the ESP8266 WiFi Modem. Code will be included at a future date.
