Wayne Westmoreland and Terry Gilman wrote some excellent games for the TRS‑80 from 1981 to 1983, including Sea Dragon and Armored Patrol. In 1995, Wayne Westmoreland released all of those games into the public domain.

Here is a description, written by Wayne Westmoreland in 1995, for each of the games.
This diskette contains the games listed below. The programs were written by myself (Wayne Westmoreland) and Terry Gilman. I’ve listed them in the order we wrote them, however I don’t remember the exact dates (old age I guess). The programs display copyright notices but I hereby release them into the public domain, do with them as you please.
TANKZONE/CMD and ARMORED/CMD
These two programs are two different versions of our first game, a version of the old coin-op game BATTLEZONE. The original was called Tank Zone 2000 (I hate that name!). We submitted it to Scott Adams’s company Adventure International whose marketing droids made us change the pyramids to houses, the flying saucer to a robot and the name to Armored Patrol.
DEFENDER/CMD and ELIMINAT/CMD
This was our second program, a version of Williams Electronics’s DEFENDER, although I believe that it was the first to reach market. Once again we had to make changes and renamed it Eliminator. However we ended being sued (or at least threatened with suit) from Williams Electronics. We gave them a percentage and then it was the “official” TRS‑80 version of Defender.
This game was our original idea, based on a suggestion from my Dad after he saw the game SCRAMBLE, however we borrowed the ending from the game PHOENIX. This game is without a doubt our favorite.
This was the first game we did for business instead of fun. We did it at the request of Adventure International who wanted a TRS‑80 version of a game written for the Atari 800 by Neil Larimer. This is our least favorite.
We wrote this game just because we liked Nintendo’s Donkey Kong and played it so much. We never marketed this game because we couldn’t get permission from Nintendo, however we had so much fun writing it, we didn’t care.
This time we got permission first. Sega gave us a license for the game ZAXXON and then we wrote this. By this time, Tandy/Radio Shack had started accepting third party programs for sale in their stores and so we struck a deal with them instead of Adventure International. However manufacturing problems on our end limited the distribution.
I hope you enjoy them,
Except for Armored Patrol there aren’t online instructions; basically use the arrow keys to move and SPACE BAR to fire. On Eliminator the ENTER key is your “smart bomb” and the CLEAR key is “hyperspace”. On Sea Dragon, the ENTER key shoots vertical missiles. Most of the games can be stopped by hitting SHIFT+S, and restarted by then hitting ENTER. SHIFT+BREAK aborts all the games.
