Not that I am aware of, although third party keyboards
were a popular upgrade at the time. I saw all kinds of
ads for them in Rainbow.

So, it might be a third party upgrade. If it's an
authentic part, then it's always possible that someone
pieced together the machine from other systems. I
don't recall if the CoCo 3 keyboard pinout will match
a CoCo 1, but it's possible. I also seem to remember
hacks people did, adding extra switches manually to
the matrix to add extra keys to the CoCo.
