In 1994, I published a Space Invaders style game for the Radio Shack Color Computer 3. Although there had been many such games for the CoCo since the first model was released in 1980, mine may have been the only version ever released to run on the OS-9 operating system.

Years later, Jamie Cho ported my game from 6809 assembly code to PowerPC Macintosh… Unfortunately, that old app won’t run on modern Intel Macs.

As luck would have it, I saw the name Jamie Cho pop up on the CoCo mailing list the other day and sure enough, it was the same one! Now I have an updated version of the app that runs on modern Intel Macs.

Thank you, Jamie!
