Content

3-D Maze

Program

Explore a randomly generated first-person 3-D maze using typed commands, with perspective-drawn corridors and a live timer tracking your escape attempt.

Audio Graph

Program

A machine code-powered audio oscilloscope displays real-time EAR port waveforms in three distinct graph modes, with live line-graph switching at any moment.

Experiment with OVER

Program

Type any two characters and watch their pixel patterns merge on screen — a hands-on demonstration of how the OVER attribute combines character bitmaps.

Mental Mania

Program

A five-disc Tower of Hanoi challenge with joystick support, colorful block-graphic discs, a 100-move limit, and a printer-ready move history.

Merge 1

Program

A tape-based mail-merge utility uses an embedded machine code block-copy routine to assemble personalized letters from a template and data file.

Metric Conversion

Program

A 17-category imperial-to-metric converter that uses a compact comma-delimited factor string and a computed GO TO dispatch table to handle everything from teaspoons to tons.

Minuetz

Program

Roll dice or let the computer decide as this algorithmic composition program builds musical scores, renders notation on-screen, and plays them back through machine code routines.

Minuteman

Program

A countdown from 10 to liftoff drives this missile launch simulation, complete with rising beep tones and an ASCII rocket that scrolls upward across the screen.

Mission Impossible

Program

Guide a nuclear operative through a robot-patrolled power station, collecting fourteen fuel rods before radioactive runaway — with custom sprites and laser hazards.

Moire

Program

Five hypnotic geometric light-show routines chain together, using XOR drawing, system variable PEEKs, and bouncing coordinates to fill the screen with evolving abstract patterns.

Mona Lissa

Program

A rendition of a woman in black and white (no color attributes used). Not a typo: contains a SCREEN$ file that is definitely not the Mona Lisa.

Money Pail

Program

Dollar bills rain from the sky — move your pail with two keys, catch up to five bills, then rush to the bank before more money falls past you.

Moon Lander

Program

Guide a lunar lander to a safe touchdown using thrust and rotation controls, with machine code sprites and collision detection driving the action.

Moonphase Astrology

Program

Enter any calendar date and this program calculates the Moon's ecliptic longitude in degrees using a multi-term astronomical polynomial expansion.

Morse rev2

Program

Type any letter or digit and hear its Morse code beep out in dots and dashes, with a user-chosen pitch — all in under 50 lines of BASIC.

Mountie

Program

A Mountie on horseback springs to life from a cleverly encoded string of digit pairs, then scrolls a red "R.C.M.P." caption across the screen.

Muffin

Program

A hypnotic animation loop draws a random character across a random screen row, then wipes it away — endlessly repeating with fresh values each cycle.

Multi Tape

Program

A tape cataloging utility that POKEs machine code to read raw cassette headers and stores up to 400 program entries across searchable arrays.

Multiply 1

Program

A pure-BASIC long multiplication routine handles numbers of any digit length, using string input and a carry-propagation array to deliver exact results.

Multiply 2

Program

A two-part educational game combines timed multiplication drills with a falling-money arcade challenge where correct math earns your chance to catch dollar bills with a pail.

Music Beep 1

Program

A BASIC music player that draws synchronized scrolling note rectangles on screen while playing multiple tunes through BEEP, with notes packed cleverly into DATA statements.

Music Beep 2

Program

A multi-song BASIC music player that precomputes an equal-temperament frequency table and uses polyphonic sound hardware to play melodies with synchronized on-screen graphics.

Music Player

Program

A three-mode music program lets you compose tunes by typing letters, play a graphical keyboard in real time, or unleash a randomised bird-call synthesiser.

New CHR$

Program

Flip your entire character set upside-down, load hand-crafted letter shapes, or restore the ROM font — all by jumping to a single line number.

New York by Night

Program

Guide your antimatter flying disc against waves of descending aliens threatening a procedurally generated nighttime cityscape, with difficulty levels and UDG sprite graphics.

Night Race

Program

Guide a UDG-sprite car down a shifting night road, dodge oncoming traffic, and chase a persistent high score in this pure-BASIC racer.

Numbers

Program

Enter any number and watch a 4×4 magic square appear — every row, column, diagonal, and corner group sums to your chosen value.

Ohio Lottery

Program

Pick your lucky numbers with this two-mode lottery generator that ensures unique draws and supports both screen copy and line printer output.

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.

Old English Fonts

Program

An interactive decorative font compositor renders large, multi-row Old English glyphs on screen, driven by swappable machine code character tables and a full editing keyboard.

Orbiter

Program

Predict when polar-orbiting weather satellites will pass overhead, complete with azimuth and elevation data for aiming your antenna at each incoming pass.

Pac Man

Program

A Pac-Man clone with custom UDG sprites, a procedurally drawn nested maze, pursuing enemy AI, and a persistent high-score name entry — all in BASIC.

PAINTsinc

Program

A complete pixel-art drawing program with ten drawing modes, joystick support, flood fill, scalable copy, and attribute-level color control packed into one BASIC listing.

Slow Message

Program

A pixel-by-pixel double-size text scroller renders any message you type using machine code for smooth scrolling — enter your message and watch it loop forever.

Sort Demo

Program

Four classic sorting algorithms — Bubble, Selection, Shell, and Quicksort — head-to-head in one program, letting you compare their performance on randomly generated arrays.

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