2068 Graphics and Trig

Program

An interactive trigonometry explorer draws labeled quadrant diagrams, parametric curves, and Lissajous figures using user-supplied SIN and COS multipliers with custom UDG graphics.

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.

3D Tic Tac Toe

Program

A fully strategic 3D tic-tac-toe game on a 3×3×3 grid, with three AI difficulty levels and all 49 possible winning lines tracked simultaneously.

Aliens

Program

Defend Earth from randomly spawning aliens using a joystick-controlled rocket launcher, with UDG sprites, multi-channel sound, and escalating difficulty levels.

Asteroids

Program

Dodge a swarm of asteroids, deploy a limited energy screen, and battle for the top spot on this pixelated space survival game's Hall of Fame.

Bars

Program

A mesmerizing infinite loop of scrolling colored bars fills the screen using only PAPER attributes and blank PRINT statements — no graphics required.

Biorhythms

Program

Plot your physical, mental, and emotional biorhythm cycles as colorful sine waves — just enter your birth date and today's date to see the month ahead.

Buster-Bill's Obsession

Program

A grid-based puzzle-action game where you steer a character across scrolling block rows, defusing time bombs before they detonate — with nine escalating difficulty levels.

Earth

Program

Dodge and shoot a drifting alien invader using custom sprite characters, a laser beam drawn with PLOT/DRAW, and lives tracked on screen.

King-Kong

Program

Navigate a multi-story building, dodge patrolling gorillas, and defeat the giant ape in this attribute-collision arcade game with a custom character set and frame-counter timer.

Kitchen Chaos

Program

Guide a frying pan across the kitchen floor to catch falling eggs in this sprite-animated arcade game with original music and hand-crafted UDG characters.

Manimation

Program

A walking stick-figure animation that pushes the UDG system to 80 characters by swapping multiple graphics tables on the fly using direct memory POKEs.

Math

Program

A four-operation math drill lets students practice addition, subtraction, multiplication, and division with score tracking and a custom division symbol built from a UDG.

Messiah

Program

A hand-crafted banner routine combines cycling border colors, multi-register AY sound chip music, and block graphic characters to create a striking animated title display.

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.

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.

Moving Waves

Program

A hypnotic animated wave plot uses sine-driven coordinates and an error-trap handler to keep running until something inevitably goes wrong.

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.

Opus

Program

Twenty custom bitmap tiles assemble into a single composite of Opus the Penguin, the character from Bloom County.

A fully playable five-card draw poker game pits you against a bluffing computer dealer, complete with betting, drawing, hand evaluation, and a watch-pawning emergency fund.

Rotating Pyramid

Program

A 36-frame rotating 3D pyramid with hidden-line removal, perspective projection, and pre-computed animation frames played back from a single large array.

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.

Sheep Dog Trials

Program

Guide your sheepdog through four increasingly complex stages, herding sheep past ponds, fences, and obstacles — all driven by SCREEN$-based collision detection.

Spacman

Program

A Pac-Man clone stores its entire maze in a string array and uses custom UDG sprites to animate a chomping character hunted by two independently moving ghosts.

Sprite 2

Program

A BASIC loader installs a self-verifying machine code sprite engine that hooks the interrupt vector, animating graphics automatically while humorous fake copyright strings scroll by.

Surface Plot

Program

A wireframe 3D surface plotter renders a ripple function using perspective projection math, with hidden-line suppression and precomputed trig for smooth results.

Swarm

Program

Guide a rocket launcher crosshair across a nighttime skyline and shoot down an advancing swarm of bees before they wipe out the city's population.

Tape Label

Program

Design and print a two-sided cassette tape index card, complete with bordered columns, program titles, and index numbers for up to 15 entries per side.

A two-player tennis game with perspective title art, direct port keyboard reading, and UDG paddle graphics that change shape based on forehand or backhand stance.

Tic Tac Toe

Program

A two-player Tic-Tac-Toe game with a pixel-drawn board, graphical X and O markers, running score tracking, and a final session winner summary.
