I have two of them to play with.

Having trouble finding a cable and connector for the keyboard.

The closest cable I can find is A Digikey 0.050 Inch / 1.27 mm pitch.

They do not have a connector for it.  The closest that I can find is 
0.040 inch / 1.25 mm pitch from Digikey.

I am not sure that either of those two are matches in any case.

The alternative is what I read someone else did was to grind down a PCB 
board finger edge to fit the socket.

Or figure out a way to splice a new connector on to the Color computer. 
I really would like to avoid that.
