A standalone Color Computer 2 & 3 emulator built for TTGO-VGA microcontroller boards. 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.
Announcement on launch →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 →Browse, build and edit CoCo disk images right in the browser. Manage .DSK and .VDK volumes, inspect directories and move files without leaving your desk — served from port 6809, naturally.
Decode and view native Color Computer graphics formats on a modern machine — a quick window into the artwork and screens that lived on CoCo disks and tapes.
View on GitHub →An AI-assisted disassembler skill for Motorola 6809 / 6309 machine code — turn raw CoCo binaries back into readable assembly to study, document and revive vintage software.
View on GitHub →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.
