Content

Beatles

Program

A two-voice AY chip arrangement of a Beatles classic, with selectable tempo and a live channel status display driven by carefully sequenced DATA statements.

Chopin

Program

A BASIC arrangement of Chopin's Prelude drives the AY-3-8912 chip directly, blending three-channel register writes with BEEP calls and a user-adjustable tempo control.

Eliza

Program

A classic ELIZA psychiatrist chatbot that drives its keyword-matching engine with a separately loaded machine code routine, blending BASIC responses with fast Z80 string searching.

Equations

Program

A simultaneous-equations quiz that generates guaranteed integer solutions and reveals them with flashing highlights — can you beat it before pressing any key?

French Vocabulary

Program

A colour-rich French vocabulary quiz that randomly selects questions without repeats, rewards correct answers with escalating beeps, and tracks your score across up to 20 words.

Genetics

Program

A configurable mouse population genetics simulator that tracks allele frequencies across 50 generations, complete with a UDG mouse icon and live selection-pressure modelling.

Glasswalls

Program

A physics-driven bouncing ball with distinct wall-collision sounds gradually widens its arc across a pixel-drawn enclosure until it comes to rest—then relaunches with more speed.

Inside Spectrum

Program

An interactive PCB diagram of the ZX Spectrum Issue 3 board, with block-graphic components, vector-drawn bus lines, expansion-port pinout, and detailed on-screen explanations of every chip.

Life

Program

A full Conway's Life implementation with a cursor-driven cell editor and machine-code evolution engine, loaded from tape and driven by a BASIC menu shell.

Mozart

Program

A complete rendition of Mozart's K. 545 sonata encoded purely in BEEP commands, with clever transposition tricks and reusable pattern subroutines packed into under 200 lines.

Multiply

Program

A multiplication quiz that rewards correct answers with an arcade money-catching game, complete with UDG sprites, chip sound, and a running bank balance.

Ohm's Law

Program

Enter any two electrical values and this Ohm's Law calculator instantly derives voltage, current, resistance, and power using all six possible formula pairs.

Parakeet

Program

A self-looping generative sound program that drives the AY-3-8912 chip through random frequency sweeps, noise bursts, and probabilistic pauses to create endless ambient tones.

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.

Question & Answer Test Generator

Program

A self-contained quiz authoring tool that lets you type questions and answers, saves them to tape, then tests you with hints and a two-attempt scoring system.

Quizmaster

Program

Build your own quiz, get hints when you're stuck, and earn bonus points for first-try answers — then save the whole thing as a standalone program.

Read & Spell

Program

A memory-training spelling game that flashes a phrase, hides it, then checks your typed answer — with a subtle string-comparison trick buried in the logic.

Spell That Word

Program

A 30-question spelling quiz that shuffles correct and misspelled options randomly — but two of its three difficulty levels were never finished.

Spellbug

Program

A pixel-magnifying spelling game that renders scrambled letters as giant mosaics and lets you hunt them down with a joystick or type your answer at the keyboard.

Word Images

Program

This random sentence generator lets you define custom word-order templates or choose from seven presets, then displays the results in a striking vertical typographic layout.
