Disk Extended Color BASIC 2.1
A standalone Color Computer 2 & 3 emulator built for the TTGO VGA32 ESP32 board. Plug in a VGA monitor and a PS/2 keyboard and you have a complete CoCo — no host PC, no operating system, just a 6809 brought to life on modern silicon. Now open source, and every part is off-the-shelf.
A full CoCo 2 emulator on an ESP32-S3, ported from Ciaran Anscomb's XRoar. MC6809 CPU, MC6847 video, dual PIAs, WD1793 floppy, USB-HID keyboard and SPI TFT output.

View on GitHub →The emulator runs on the TTGO VGA32 V1.4 — a tiny ESP32 development board with everything a Color Computer needs already on it: a VGA connector for the monitor, two PS/2 ports for keyboard and mouse, audio out, and micro-USB for power and flashing. Nothing to solder.
Boards are widely available — search "TTGO VGA32 V1.4" on Amazon and most electronics shops.
Build, browse and edit CoCo disk images without leaving the browser. Open a .DSK or .VDK, inspect the directory, drag files in and out, and save it back — the same workflow you'd want at a real CoCo, served from port 6809.
CoCoByte started as the TANDY Color Computer user group in Colombia and grew into a collective of builders keeping the platform alive — writing emulators, designing hardware, and bringing our collection to the retro-computing community in person.
Whether you want to flash an emulator onto an ESP32, manage your disk images, or just talk 6809 — the door's open.
