I have used a Teensy 2.0 ($18-ish) to read hardware buttons and emit USB keyboard sequences to a desktop computer. These are commonly used for home arcade controls. I was using it to read a USB arcade joystick and send out iCade keypresses to my iPad with the Apple USB dongle. I had another mode where it remapped the device to MAME emulator keyboard keys.

You can find an Arduino Leonardo clone for around $11 (I use a dealer in Missouri, who ships fast and free). It can act like a keyboard/mouse to a PC, so you would just need to read the CoCo keyboard switches.

Thus, for $11 and some connection hardware, you would make that CoCo keyboard usable on a PC.
