The download has a TZX file, a plain-text listing (.b81) and screenshots for each program, in tape order by side, with the tape’s contents list (TS PDL 1004.txt) and photos of the cassette and its label. Program names follow that list; where it says “Unknown”, the name of the program’s own page is used.

Content

64K Memory Test

Program

A two-pass RAM test that pokes every byte of the upper 32 KB with 255 then 0, reporting any failure instantly on-screen and to the printer.

64K Tape Test

Program

A meticulous cassette tape reliability tester that fills 32 KB of string arrays with known patterns, saves them, then counts every byte that comes back wrong.

Asteroids

Program

Dodge falling space rocks with a block-graphic ship — can you survive long enough to see the asteroids grow and the speed double?

Bounce

Program

A physics-driven bouncing ball animation uses randomised launch direction and a damped-bounce velocity model to simulate gravity across the screen.

Clerical Spell List D&D

Program

Enter all seven levels of D&D clerical spells, store them in packed string arrays, and print a formatted spell reference sheet on an 80-column printer.

Crasher

Program

Guide your "V" across a scrolling screen, smashing alphanumeric characters for points while dodging deadly inverse-video life forms in this collision-detection arcade game.

Cypher

Program

A keyword-driven Vigenère cipher that both encodes and decodes secret messages, using a pre-built substitution table and character-code arithmetic.

D&D Character Generator

Program

A full D&D character generator that rolls 4d6-drop-lowest stats, calculates class-specific hit points, scales starting gold by level, and randomly assigns tiered magic items.

D&D Track

Program

A full RPG combat tracker handling hit points, troll regeneration, wound binding, healing, and an arbitrary dice roller — all managed through a compact menu-driven interface.

Day of Week Calendar

Program

Enter any date between 1900 and 1999, and this compact BASIC program works out exactly which day of the week it fell on.

Dice

Program

A dice-rolling program uses a clever inverse-video character array and string-slicing trick to render up to five fully graphical die faces at once.

Donkey Kong

Program

A Donkey Kong homage with scrolling barrels, ladders, diagonal jumps, and screen-read collision detection — all squeezed into pure BASIC.

Druidical Spell List

Program

A Dungeons and Dragons Druidical spell organizer that collects spell names level by level and formats them into a tidy printed reference list — no graph paper needed.

Dues Tracker (64k)

Program

A full membership database for a users group — enter, change, sort, and print records, with automated dues-chasing letters and a machine-code scrolling spreadsheet view.

Dungeon Generator

Program

A BASIC dungeon map builder lets you scatter rooms, pits, lakes, walls, and doors across a full-screen grid — then print the result.

Ford Falcon

Program

A hand-crafted animated falcon built from block graphics characters reveals itself piece by piece, timed by busy-loop delays — complete with a dive-approach animation and a 1983 artist signature.

Garbage Gobbler

Program

Race against a countdown timer to gobble block-graphic garbage off the screen — this BASIC game uses display-file PEEKs and animated title screens to keep things lively.

GTO

Program

A block-graphics GTO badge drawn entirely in BASIC, with animated letter-by-letter reveal, diagonal curved edges, and a mesh-fill interior — all without machine code.

Illusionist Spell List

Program

A Dungeons & Dragons Illusionist spell-list manager that packs multi-level spell names into string arrays and prints them on an 80-column printer.

Load Tracker

Program

This D&D encumbrance calculator handles exceptional Strength scores, tracks weapons, armour and supplies, then tells your character exactly how fast they can move.

London Bridge

Program

Guide your piece across a randomly generated bridge grid using numeric keypad directions — one wrong step and you're in the water!

Lunar Excursion Module

Program

Guide a crippled lunar lander to the Moon's surface by hand, managing retro-rocket burn rates against real physics — before your oxygen runs out.

Magic Users Spell Test

Program

A spell-list builder for D&D Magic-Users that accepts all nine spell levels and formats them into printable 80-column reference sheets — entered via GOTO, never RUN.

Mandalas

Program

Enter a number from 1 to 100 and watch concentric rings of plotted points bloom into a mandala — angular resolution is entirely in your hands.

Maze Dash

Program

Navigate a dollar-sign sprite through a randomly generated barrier maze, watching your 20,000-point score erode with every wall collision and wasted move.

Microworld

Program

A procedurally generated pixel landscape with a scrolling animated header and a customisable inverse-video title — all in a compact BASIC program.

Moon Base

Program

Guide a lunar lander to a precise touchdown using thrust and drift inputs — fuel, velocity, height, and a random landing zone keep every descent unique.

Moonbase

Program

Guide your spacecraft down to the lunar surface using thrust and drift controls — but watch your fuel, velocity, and the randomly placed landing pad position.

Phasor

Program

A space shooter where timing your keypress to the alien's screen column is the only weapon — and three difficulty levels keep the pressure rising.

Playboy Bunny

Program

A printer-art program that assembles a famous bunny silhouette from block graphics, with a polite "is your printer on?" check before committing to output.

Rear Gunner

Program

Move your crosshair across the screen, line up the shot, and press fire — but only a pixel-perfect hit will trigger the explosion in this deceptively simple shooter.

Reject Analysis Program

Program

A full business reject-tracking system built in BASIC: enter transactions, clear records, and print aged delinquency reports across 19 input devices and 15 reject codes.

ROM Copier

Program

A clever two-stage bootstrap that copies the ROM into RAM via machine code, then saves the result to tape — hardware switch required.

Wink

Program

A three-frame ASCII face blinks and opens its mouth in a tight animation loop, using FOR–NEXT timing and a clever border design.

ZX81 Quiz Builder

Program

Build and take your own quizzes — multiple choice, true/false, or direct answer — with this ingenious packed-string data engine that stores every question, answer, and explanation in a single array.
