For those who want to keep their CoCo looking exactly as it did, we present KeyFix3. This is the clicky key version.
This circuit board (keyboard NOT included) replaces the metal plate and Mylar sheet with individual switches and a wired connection. Looks and feels like the original, except for the 'CoCo2 mode' switch. This converts the ALT/CTRL keys to UP/DWN arrow for older games, by a handle extending out of the cooling vents on the bottom. No cuts, just replace parts.
We also have a quiet version, or even a bare board if you'd rather install your own switches. Check our blog for details.
