A 16-program collection from the Capital Area Timex Sinclair User Group focused on graphics, drawing tools, and educational software.

Content

3D Shape

Program

A full homogeneous-matrix 3D wireframe cube renderer, hand-coding rotation, scaling, and translation without any built-in 3D support—pixel by pixel.

Banner

Program

A clever banner printer that hijacks the screen renderer and POINT to enlarge any character string onto a 2040 printer in normal or inverse.

Bar Chart

Program

A dot-density bar chart routine reads paired height and density values from DATA lines to render variable-fill bars using only PLOT commands.

Character Editor

Program

Design custom UDG characters pixel by pixel on a live grid, with instant byte-value readout and automatic RAM updates as you draw.

Characters

Program

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.

Color Plot

Program

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.

Doodle

Program

A colourful, noisy joystick doodle pad for small children, complete with a bouncing cross cursor, random ink colours, and directional beeps for every move.

Geography Quiz

Program

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.

Headline

Program

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.

PieChart

Program

A polar-coordinate pie chart renderer that uses dot density and angle ranges stored in DATA lines to fill wedges with evenly spaced points.

Pix Fix

Program

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.

Random Fan

Program

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.

Spanish Tutor

Program

An interactive Spanish tutor automatically conjugates any regular verb you enter and teaches suffixes, opposites, and question words with scrolling example sentences.

Spectrum Draw

Program

A machine code art package from Your Computer gets a TS2068 conversion—with BASIC-driven parametric circles, screen save/load, and text overlay routines.

UDG Custom Graphics

Program

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.
