Released in 1980 by Tandy Corporation and sold through Radio Shack stores, the TRS-80 Color Computer (nicknamed "CoCo") was one of the first affordable home computers with color graphics and sound.
It used the powerful Motorola 6809E CPU and the MC6847 Video Display Generator.
This emulator uses the exact MC6847 VDG character generator ROM data — 128 characters (64 uppercase + 64 lowercase/symbols), each defined as 8 rows of 5-pixel-wide bitmaps. Characters are rendered pixel-perfectly as they appeared on real CoCo hardware.
This emulator supports real CoCo cassette formats:
Drop ANY file of ANY type directly into memory at a specified address. Features auto-detection, byte-swap, pre-fill, hex preview, memory map visualization, upload history, and memory dump/download.
Click any input field to type into it — keyboard input is automatically routed away from the emulated CoCo. Click the screen or press Escape to return keyboard control to the emulator.
Audio: Click-free 6-bit DAC with ring buffer, linear interpolation, and DC offset removal.
