Content

15/20 Word Processor Program

Program

A 15-page word processor with mailing-label printing, tape save/verify, and a self-installing machine code routine — all packed into one BASIC program from 1985.

3D Driver

Program

Steer a UDG-rendered car down a perspective road while random drift fights your inputs — stay on track as long as you can to maximize your score.

5 Interesting Routines

Program

Six utilities in one program — BASIC memory readers, custom input handlers, a machine-code error message printer, and a ROM integrity checker — all selectable from a menu.

64 Column BASIC

Program

Machine code driver that patches the display routines to render BASIC PRINT output at 64 columns, with TS2040 printer support and an interactive demonstration of the mode's capabilities.

CHR

Program

A four-section character design toolkit lets you inspect, draw, convert, and save custom graphics — complete with binary, decimal, and hex readouts and Microdrive support.

Read and Spell

Program

A deceptively simple reading-and-spelling quiz picks a random phrase, times how long you see it, then checks your typed answer with a subtle first-character loophole.

Relocate

Program

A BASIC-driven Z80 machine code relocator that copies a routine to a new RAM address and automatically patches embedded absolute jump and call targets.

Renum

Program

A two-pass BASIC renumbering utility that patches both line headers and embedded floating-point GO TO targets directly in memory — no ROM calls needed.

Renumber 1

Program

A machine-code-powered BASIC renumbering tool lets you reassign line numbers across a range, prompting for start, step, and stop values with surgical precision.

Renumber 2

Program

A direct-memory BASIC renumbering tool that rewrites line numbers in place using PEEK and POKE on the program's own stored structure.

Robot Invasion

Program

A Space Invaders-style shooter with machine code routines, custom UDG sprites, and escalating difficulty — all packed into a tight BASIC game loop.

Rockets

Program

A countdown of flashing borders and beeps precedes an ASCII rocket launch, then random stars scatter across the screen in celebration.

RomeoT

Program

A carnival weight-guessing game hides a remarkable self-listing routine that decodes its own tokenized BASIC and renders each keyword as hand-drawn letterforms on screen.

RSLOAD

Program

A joystick-driven text-stamping tool that lets you position, color, and print any string anywhere on screen — then save or load the result.

RubicCube

Program

A fully interactive Rubik's Cube simulator with face rotation, scrambling, move recording, and tape save/load — complete with custom block graphics for the cubies.

Santa

Program

Guide Santa through five increasingly difficult stages — blizzard, rooftop drop, chimney lift, snowball dodge, and sleigh launch — in this fully configurable multi-stage arcade game.

Saturn Lander

Program

Guide a spacecraft down through Saturn's rings and land safely on the rocky surface — this BASIC lander game packs machine code routines, UDG graphics, and pixel-perfect collision detection.

Saver

Program

Load any tape header and instantly get a ready-to-use SAVE command back — this utility decodes file type, name, length, and start address automatically.

Scrabble

Program

A fully playable Scrabble implementation pits up to three human players against a computer opponent, with a color-coded bonus-square board and cumulative score tracking across multiple games.

Ships Attack

Program

Four color-coded bombs rain down at ever-increasing speed — dodge them all with just two keys and watch the difficulty suddenly double at 25 points.

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