Despite nearly matching the longevity of the Commodore 64, Tandy’s Color Computer line never really had the third party software support that the Commodore 64 and other 8-bit computers of the time had. The fact that Radio Shack did not really court third party development combined with the fact that the hardware was only sold at Radio Shack probably had something to do with that.
Buzzard Bait is one example of the games you would typically find for this system. As you can see, it is a blatant rip-off (er…clone) of the arcade game Joust. It actually isn’t terrible (except for the sound which was a limitation of the CoCo series). There were lots of clones of more popular arcade games on the Coco but the quality varied wildly. Some were decent like Buzzard Bait and some were terrible.
Buzzard Bait was released by a company called Tom Mix Software in 1983. Like much of the software for the CoCo, you could only find it easily via mail order but the company did have a BBS that you could order through so that’s pretty cool. It was available on both disk and cassette and given the fact that it wasn’t marketed through major retail establishments, original copies are probably pretty rare. I didn’t see one on eBay at a glance and that’s usually a pretty good indication. This is one you will probably need emulation to try. However, for a better conversions of Joust, you are better off checking out the official conversions for the Atari 8-bit, Atari 7800 and Atari ST.
