A new version of #ugBASIC, the open source isomorphic #BASIC compiler, has been released for #TRS80 #ColorComputer 1/2 and 3 (check under Hardware > Targets).
ugBASIC is a cross-compiler for #Linux and #Windows, for writing simple language games, that can run on dozens of different home computers, and 8-bit consoles.
There is also a convenient built-in IDE for Microsoft Windows, and even a sandbox.
