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.
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.
Dodge falling space rocks with a block-graphic ship — can you survive long enough to see the asteroids grow and the speed double?
A physics-driven bouncing ball animation uses randomised launch direction and a damped-bounce velocity model to simulate gravity across the screen.
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.
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.
A keyword-driven Vigenère cipher that both encodes and decodes secret messages, using a pre-built substitution table and character-code arithmetic.
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.
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.
Enter any date between 1900 and 1999, and this compact BASIC program works out exactly which day of the week it fell on.
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.
A Donkey Kong homage with scrolling barrels, ladders, diagonal jumps, and screen-read collision detection — all squeezed into pure BASIC.
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.
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.
A BASIC dungeon map builder lets you scatter rooms, pits, lakes, walls, and doors across a full-screen grid — then print the result.
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.
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.
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.
A Dungeons & Dragons Illusionist spell-list manager that packs multi-level spell names into string arrays and prints them on an 80-column printer.
This D&D encumbrance calculator handles exceptional Strength scores, tracks weapons, armour and supplies, then tells your character exactly how fast they can move.
Guide your piece across a randomly generated bridge grid using numeric keypad directions — one wrong step and you're in the water!
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.
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.
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.
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.
A procedurally generated pixel landscape with a scrolling animated header and a customisable inverse-video title — all in a compact BASIC 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.
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.
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.
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.
A clever two-stage bootstrap that copies the ROM into RAM via machine code, then saves the result to tape — hardware switch required.
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.
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.
A three-frame ASCII face blinks and opens its mouth in a tight animation loop, using FOR–NEXT timing and a clever border design.
