I haven't found any PDF tech manuals on-line for the CoCo's, which
surprises me.  There are certainly a lot of others that have been
documented on-line. I have a technical reference for the CoCo1/2/3. I can
send you some scanned schematics, if you wish?

Yes, they are just momentary contact switches in X/Y. They are laid out
the same as the CoCo3. I know there are schematics of that readily
available on-line. The CoCo1 doesn't have all the keys that the CoCo3
does, though.
