[Coco] Coco keyboard for PC

[Scott Wendt]

The easiest way to do this, for me at least, is to use an arduino to decode the keyboard matrix and connect it to a PC over USB as an HID device.


Here is a link on using arduino as an HID device:

There is enough information in the CoCo technical reference to be able to decode the keyboard and the basic idea is the same as listed in this article:

Well the coco keyboard matrix is pretty easily exposed via that little
(and breakable) ribbon cable connector... you'd think with the proper
combination of resistor values, wired up to a PC joystick port, you
could probably find a way to have a unique joystick value returned for
each key pressed.  But that's a long way from a solution.  Don't think
anyone has tried coco keyboard on pc, always the other way around.
