I was under the impression that the CoCo was sold first (which was

Early CoCo1s were silver too...
purpose machines (I'm not sure if they all had 64K

The original chiclet keyboard has one advantage-- you can put a template
over it to give special meaning to each key, and these templates were
shipped with some programs.
YEs, I have a couple. I can't remember which programs they're for,
though, and I am not going to hunt for them to check...
