There is a large collection of Tandy CoCo programs and manuals at
and it should be easy to get copyright dates from the manuals.

For a while there was very good support for the CoCo on MESS/MAME but
there may not be anyone currently working on that emulation. Glad
to see that you want to work with CoCo emulation. MAME has the best
CoCo graphic emulation available.
