Mike,

>From what I remember, the Model I has a slightly different keyboard matrix 
than the CoCo. It has an 8x8 matrix, whereas the CoCo's is 8x7.  I think the 
only keys in the 8th row of the Model I matrix are the SHIFT keys. The other 
rows are mostly the same, but a few things have been moved around.

The likely scenario is that the keyboard in your CoCo is a third-party 
product made for the CoCo. I have a couple different third-party keyboards. 
One of them does look and feel pretty much like a Model I keyboard except 
the color scheme is sort of reversed (light-colored keys for the 
alpha-numerics; black keys for ENTER, BREAK and arrows).
