Help categorize the TRS-80 software archive
Nearly 30,000 programs, and almost none of them say what kind of program they are. Mark whatever you recognize. Pick as many words as fit — a game that teaches arithmetic is Game, Math, Education — then send the page. Everything is reviewed by hand before it goes anywhere near the archive, so a best guess is worth more than a blank.
Important Note: Do not do multiple entries of the same program. If you flag Super Nova by Big Five once, all Super Nova by Big Five entries will get updated. No need to waste your time flagging each Super Nova

COMPUTER SHACK --- --- ASSAULT by Dunlevy & Frayer Strap yourself into the dimly lit ATV (All Terrain Transport), check the motor, the laser's, and visibility. Now prepare yourself for an underground trip that you won't soon forget If you live! After weeks of exploring and mining, you've accumulated quite a tidey sum of gold. But just as you thought the adventure to be over, you stumble upon a part of the mountain that is soon to become your battle ground, if not your grave. These wide open caverns are inhabited by strange creatures set upon stealing your gold and maybe even your life. You can battle them in your laser equipped ATV, but beware! Along the walls grow rather harmless looking mushrooms, that is until you've touched one. But all of this is childs play compared to battling NODRID, the emperor spider of this hellish place. His bloodthirsty fangs will make short work of any unwary adventurer, but you will not find him such an easy prey! Model I/III Tape $19.95 Disk $24.95

ASTEROIDS - A FUN ARCADE GAME ASTEROIDS, like INVADERS, stemmed originally from the arcades. For those not familiar with the game, the idea if that you take the place of a space ship which encounters a shower of Asteroids. You have to dodge them and annihilate them with your ray guns. The problem is every time you hit one with your laser beam it splits up into a number of others, all of which are potentially dangerous to your craft. When a asteroid hits you your craft is destroyed and one life is taken from your score. This particular version has a number of enhancements. You can rotate the ship around its axis and fire in different directions, you can supply thrust to your ship, and if the going gets rough, then you can enter hyperspace. To keep your fingers active, from time to time you encounter fast moving alien ships. These crafts are undoubtedly ruthless, they fire off rays in all directions, and if they hit your ship you loose a life. A major plus feature of this game is that the game parameters can be changed. The player has control over the speed of the game, the initial number of asteroids, the increase in asteroids per frame and the starting number of lives. Written in machine code, ASTERIODS is fast and highly enjoyable. Memory Requirement 16/32k TRS-80 Tape/Disk Model 1 & 3 Tape 11-2101 Disk 11-2108

ASTRO NAVIGATOR - MORE THAN A SPACE GAME To label this program as a game is to underplay the incredible realism of what can best be described as a simulation. The software programs your TRS-80 or SYSTEM 80 to produce a complete and highly accurate simulation of the solar system. All the orbits of the various planets are correctly calculated, as are their orbital speeds and gravitational pulls. Each time the game is played the planets and stars in the solar system are differently placed, but still in correct relationship to each other and to the Sun. Hence every game is different and presents different problems to the player. The purpose of the game is to blast off from the planet of your choice and travel throughout the solar system. There are no prizes, no free goes, nothing else. If you succeed in making a landing on another planet then your reward is the thrill of having been able to do so. Believe us when we state that it really is a thrill. Part of the reason is that the game is unbelievably difficult because all the physical laws and relationships are obeyed. Although the player of this game has the help of a computer, it will only tell him the statistics of the journey. It remains for the player to decide how much fuel to take on, what thrust to use, whether to try to blast off slowly, or whether to launch at a somewhat higher velocity. Apart from the flight data, there are maps of the other planets, of the inner planets and a close up view of a planet when the craft reaches a specific proximity. Superimposed on these maps is the position of the spaceship together with the last few positions that have been occupied. At all times, gravitational pull, the laws of momentum and various other considerations are acting on the crafts course. We should add that graphics are only a subsidiary part of the simulation, yet this program remains tremendously engrossing, attributable we feel to the high level of skill required to master ASTRO NAVIGATOR.
