Games by Wayne Westmoreland and Terry Gilman

written by Matthew Reed

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.

You can download an archive containing two single-density disk images with all of the games here: AIGAMES.ZIP

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.


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.


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,
Wayne Westmoreland


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.

Mark McDougall says:

I can’t for the life of me work out the correct PDRIVE settings to read this disk image in Model III NEWDOS/80!?! I can seemingly read the directory in SU32 using N3D, but no luck in NEWDOS/80.

Are you able to help?



Matthew Reed ( says:

The disk was a single-sided double-density disk formatted by Model III LDOS. I couldn’t figure out any PDRIVE settings that could read it either, but I never used NEWDOS/80 very often.

To make things simpler, I changed the download to contain two single-density disks formatted by TRSDOS 2.3. These should be readable by any Model I or Model III operating system except TRSDOS 1.3 (which could easily convert them).

By the way, here are the PDRIVE settings I used to read these new disks:


Ira says:

When in doubt, I always just try Matthew’s excellent TRSREAD disk extraction program. If the format is at all standard, the contents will simply be extracted. You can then create your own DSK image as you see fit, based on those extracted files without worrying about the PDRIVE.

I believe that Phil Ereaut’s “Emulator File Display” program will also display the characteristics of a DSK/DMK image. In this case, it advised:

“35 Track S/Density S/Sided Sec/Cyl. = 10 (10 * 1)”

I admit this information is only useful to someone familiar with PDRIVE, but it does provide enough information to someone who is.

I thought there was a program out there which actually spat out the PDRIVE codes for a given disk but it has slipped my mind at the moment.

Hello to you Wayne and Terry.

I haven’t heard from you since I last visited you guys in 1981. I wrote Reign of the Red Dragon and watched with amazement as you constructed your excellent machine language games. As I recall you were finishing up Eliminator and making explosions. It might interest you to know that I’ve written a novel based on my game and hope to have it published soon.

Anyway, I just hope everyone enjoys your programs as I still do. My model III still works and I play the games now and then.
