A full homogeneous-matrix 3D wireframe cube renderer, hand-coding rotation, scaling, and translation without any built-in 3D support—pixel by pixel.
A clever banner printer that hijacks the screen renderer and POINT to enlarge any character string onto a 2040 printer in normal or inverse.
A dot-density bar chart routine reads paired height and density values from DATA lines to render variable-fill bars using only PLOT commands.
Design custom UDG characters pixel by pixel on a live grid, with instant byte-value readout and automatic RAM updates as you draw.
Step through every character in the set, watching its 8×8 pixel grid and raw ROM byte values revealed row by row with a keypress.
A pixel-precise joystick drawing tool with circle stamping, color cycling, sound feedback, and direct tape save — all packed into a tight real-time loop.
A colourful, noisy joystick doodle pad for small children, complete with a bouncing cross cursor, random ink colours, and directional beeps for every move.
A hand-drawn color map of North America sets the scene for a state-capitals quiz that reads your answer and tells you where you went wrong.
A banner printer that reads UDG pixel data directly from memory, transposes the 8×8 bitmap, and expands every pixel into a chunky 4×3 block character on the 2040 printer.
A polar-coordinate pie chart renderer that uses dot density and angle ranges stored in DATA lines to fill wedges with evenly spaced points.
A two-mode pixel art editor with machine code routines handles drawing, erasing, screen panning, tape save/load, and even partial-screen saves in three sizes.
A mesmerising animated fan pattern traces lines between opposite perimeter points with randomised colours, using a hand-rolled vector line-drawing routine instead of DRAW.
An interactive Spanish tutor automatically conjugates any regular verb you enter and teaches suffixes, opposites, and question words with scrolling example sentences.
A machine code art package from Your Computer gets a TS2068 conversion—with BASIC-driven parametric circles, screen save/load, and text overlay routines.
A three-mode pixel editor lets you draw single UDG characters, 16×16 sprites, and massive 23×24 sprites, then POKEs them directly into UDG RAM.
