[Coco] keyboard test

[Rick Ulland]

This is all good info

G O W <SPACE> 7 / SHIFTx2  is row PB7, which is the mylar trace and 
keybd connector 16, on the edge farthest from #1. So yah, that edge of 
the ribbon times the edge of the metal backplate the ribbon comes out 
from) could be bad.

It's also IC 5 pin 17 but I just said that to prove I got the book out 
to doublecheck. It's got to be old plastic is old that tears at the 
corners. Kinda like me;-)

Good luck, and enjoy your new keyboard!
