ISTUG Public Domain Library 7

Date: 198x
Type: Cassette
Platform(s): TS 2068

A public domain library tape from the Indiana Sinclair Timex Users Group (ISTUG) holding programs whose names run from O to R: a flight game, graphics editors and pattern generators, music, games, quizzes and an astronomy program. There are 22 programs, counting the four parts of Pixel Sketch and Graphic Editor as one.

The download has one file per program in the folder ISTUG7, plus istug7.tap, an image of the whole tape. That image and eight of the program files (OVERS 1, PSGE, psge1, psge3264, Quake, QandA, Race and Racer) are TZX files with a .tap name. Several blocks in the tape image are short, and it holds programs that are not among the separate files: Poker 1, Poker 3, PRINT, printhead, Pro Loader, Pro Prog and PROGRAM T.

Content

Airplane

Program

Pilot a flight from London to one of ten world cities, juggling thrust, flaps, and rudder across multiple turns to nail a perfect landing and maximize your score.

Death Race

Program

A timed car-chase game with custom UDG sprites, SCREEN$-based collision detection, and a randomly wandering enemy that you must hunt down before the clock runs out.

Earthquake

Program

A Z80 machine code earthquake effect shakes the entire screen, loaded from BASIC DATA statements into a relocatable 80-byte routine you can drop anywhere in memory.

OVERS 1

Program

See what happens when two characters share the same screen cell — this interactive tool visually demonstrates XOR overlay printing with instant labeled results.

Pablo Pixelo

Program

Design custom 8×8 pixel characters, pack them into pictures, and watch a self-verifying machine code routine power a "Big-Bits" display feature in this complete UDG toolkit.

Pangolins

Program

A self-learning animal guessing game that grows its own binary decision tree at runtime — teach it new creatures one wrong guess at a time.

Patterns 2

Program

Two mesmerizing pattern modes — randomized diagonal line fills and symmetrically mirrored pixel scatter — cycle through colors in this hypnotic display generator.

Peace

Program

A multi-mode sticker generator that combines custom UDG artwork with printer output to produce peace-dove graphics or personalized address labels.

Piano

Program

A playable piano simulator with custom UDG key graphics, three octave modes, and nine adjustable note durations—all driven by a single BEEP command per keypress.

Pipeline

Program

A two-player pipe-laying strategy game with a built-in AI opponent, three pipe shapes drawn with PLOT/DRAW, and a machine code BASIC flow-tracer hidden in its own listing.

Pixel Sketch and Graphic Editor

Program

A comprehensive pixel art and graphic editor with machine code acceleration, three video modes, joystick navigation, and over a dozen drawing and manipulation tools packed into one program.

PixelPrint

Program

A machine code routine lets you place text strings at any pixel position on screen, with independent x and y displacement between characters for diagonal or scrolling effects.

Planet Finder

Program

Calculate where any planet, the Sun, or the Moon sits among the zodiac constellations for any date, then see it plotted on a schematic star chart.

Plot demo

Program

A hidden-line 3D surface plotter with optional crosshatching, ported from a BBS download, uses a horizon-array technique to suppress depth-obscured lines.

Poetry

Program

A random poetry generator that picks words from fifteen thematic lists and assembles them into moody, surreal four-line verses — generating a fresh poem every few seconds.

Poker 2

Program

A complete draw poker game where you bet against the computer, with shuffling, hand evaluation, card drawing logic, and a full betting system packed into BASIC.

Polygons

Program

Watch every polygon from 4 to 20 sides fill with all possible diagonals, each one computed and drawn with a neat combinatorial formula on screen.

Psychic

Program

A self-working letter-finding trick that uses matrix transposition to "psychically" home in on any letter the user secretly selects from a shuffled grid.

Q and A

Program

A customizable quiz game that randomizes question order, scores two attempts per question, and gives letter-hint clues before revealing the answer.

Racer

Program

Pick your racer, place your bet, and watch nine competitors sprint across the screen in this BASIC racing game with UDG sprites, sound effects, and a world-record timer.

Note: Type-in program listings on this website use ZMAKEBAS notation for graphics characters.
