[Coco] Mechanical keyboard upgrades for the CoCo

[Dave Philipsen]

Remember that on a PC style keyboard the '2' key IS the '@' key.  Why would the scanning software have to believe that the '@' key was pressed when it KNOWS that only two keys have been pressed. What if you erase the '@' character from the keycap? Does the keyscan still see that the '@' key has been pressed?

> 
> 1) 2 key pressed
> 2) 2 key released, shift key pressed, @ key pressed
> 3) @ key released, shift key released, 2 key pressed
> 4) 2 key released
