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

Light-Pak 2 [LightPeg EndRun Life9]MISSING
This Weekend: STIK IT to your TRS-80 That's right! Esmark's VIDIET-STIK light pen has the TRS-80 CONNECTION for LEVEL I & II. Your 4K to 48K TRS-80 System will come alive under your VIDIET-STIK within minutes of its arrival. That's because there are no wires to solder or traces to cut. You're up and running as fast as you can plug the interface into your system's cassette EAR-jack, CLOAD our custom LIGHT-WAVE demonstration software and RUN. And because the interface has a plug for your recorder, you won't have to unplug it again when loading your other software tapes. The interface allows them to pass right thru whenever you're not using the pen. It's exclusive 'switched tip' design means the pen's electrically isolated from your system when it's not in use. Just point & press! It's that simple Plug, CLOAD and RUN. And have we got the software for you to RUN with! Our demonstration tape includes a calibration program (used to adjust the CRT's brightness and contrast) plus STIK-TAC-TOE, AWARI and TOWERS. Two challenging games and a puzzle that will keep grownups and children Stik'ing it to your TRS-80 for hours. And there are instructions provided so you can begin writing your own light pen programs (lightware) for fun or profit (Level II). Or, just sit back and enjoy our LIGHT-WAVE tapes each month. Esmark's unmatched commitment to lightware can bring you up to five new games, puzzles, drills & educational quizzes or simulations each month. Our current LIGHT-WAVE releases are: LIGHT-PAK 2 - LIGHTPEG (4 peg-jump puzzles) ENDRUN (Othello with a 'twist') (LEVEL II) LIFE9 (Conway's LIFE with mutations) Price: $19.95 (including postage & handling) LIGHT-PAK 3 - LITEGAMMON (Backgammon you'll Stik with) (LEVEL II) STIKWUMPUS (Caves with a little 'lite') MAZEMASTER (Maze after maze to poke thru) PRICE $19.95 (including postage & handling) ESMARK INCORPORATED 507 1/2 E.

Linear Correlation [Part of TAPE MANAGER-GRAPHICS-STATISTICS]MISSING
Tape Manager/Graphics/Statistics, CS-2301 (4K) $7.95 . Tape Manager Tape manager is a cassette tape data management system for the 4K Level I TRS-80. This program allows you to use long cassette tapes (C-60s) to store up to 8 programs. Each program can be later located automatically by the Tape Manager program. Function Graph Function Graph helps you graph equations of the form y=f(x). Functions of any type (exponentials, parabolas, ellipses, etc.) may be represented graphically using this program. Function Graph allows you to enter both x and y limits, or will scale the y-axis automatically. Statistics The following five programs provide the Level I owner with statistical computations. All will load and run in 4K of memory. ELEMENTARY STATISTICS computes the mean, variance, and standard deviation for a population or a sample. LINEAR CORRELATION allows you to determine the strength of the linear relationship between two variables. The primary statistic provided is the linear correlation coefficient. In addition, the program computes the means and variances of the variables. t-TEST determines whether the differences between the means of two groups are statistically significant. You may choose either matched pairs or standard design. ANALYSIS OF VARIANCE performs an analysis of variance on 3 to 6 groups to determine whether the variances of the groups are significantly different. ANALYSIS OF COVARIANCE is useful for same subject designs. The primary statistic computed is the F-value.

All linear programming inequalities can be put into this form, and solved by LINEAR PROGRAMMER. Further, if an answer does not exactly exist, the 'nearest' solution will be found. Data input is simple, and the method used is fast and efficient (the Khachian algorithm). LINEAR PROGRAMMER is written in BASIC and can even be incorporated into other linear programming software as a utility. Requires 16K. Price: $29.95 Cassette $33.95 Diskette $36.45 Disk
