Moon Rescue
Pilot a rescue craft to save stranded astronauts from the lunar surface, dodge scrolling terrain, and dock with a moving mothership in this arcade action game.
User Defined Graphics (UDG)
Stellar Fighter
Pilot a space fighter through escalating alien waves, managing phasor energy and hull damage while enemy sprite designs evolve as your kill count climbs.
CHR TEST
A two-mode CHR$ explorer that quizzes you on ASCII codes against a ticking bomb timer, then lets you inspect every printable character’s raw font bytes.
CHRs Gen
A font-remapping utility that rewrites every character definition in RAM, then auto-prints instructions before wiping itself — leaving behind a boldened printer font.
Tunnel Run
Navigate your spacecraft through four increasingly dangerous sections — missile tunnel, asteroid field, winding passage, and landing pad — in this multi-stage survival game.
Alien Blaster
Defend your planet by blasting two distinct alien types before five land — a BASIC shoot-em-up with custom characters, pixel-precise collision detection, and persistent high scores.
Stuntman
Hold a key to build speed, release at the right moment, and watch your stuntman attempt to clear a row of double-decker buses in this arcade jump game.
Four Stroke
An animated four-stroke engine diagram cycles through induction, compression, ignition, and exhaust using custom-designed graphics and a piston that really moves.
Snaker
Guide a growing snake around a dot-filled playfield, racing the clock while dodging your own body in this attribute-based collision game with machine code sound.
Popup Menu
A joystick-controlled popup menu framework with UDG-drawn border boxes and a five-item menu bar, ready to drop into a graphics application.
Checkers
A fully playable checkers game with computer AI, custom piece graphics, king promotion, and a coordinate-based move input system packed into under 170 lines of BASIC.
Galactic Monsters
Pilot your spaceship through eleven homing monsters using custom-drawn sprites, with enemies growing smarter and faster each wave you survive.
QBERT
A BASIC Q*bert clone with joystick control, procedurally drawn isometric pyramid, UDG sprites, and ATTR-based collision detection across escalating difficulty sheets.
Crazy Balloons
Pilot a balloon through four increasingly treacherous maze stages, dodging asteroids and your own ink trail — with custom sprite characters and color-based collision detection.
Santa’s Christmas Nightmare
Guide Santa through five increasingly brutal stages — blizzard, rooftop drop, chimney lift, snowball gauntlet, and a nail-biting altitude sprint — in this multi-stage Christmas action game.
Cannon Balls
Dodge, catch, and survive as cannon balls bounce unpredictably around the screen — can you protect your catchers before all 50 shots are gone?
Poojan
A three-stage arcade shooter with user-defined graphics, a bonus system, animated enemy wolves, and a full Hall of Fame name-entry screen.
Mike’s Notebook: BITS
I like to work with computer graphics on the TS2068 and Ifrequently need to look up bit patterns for User Defined Graphics characters. Knowing the bit patterns of a specific byte can also help to better understand machine code among the many other uses.
