A full homogeneous-matrix 3D wireframe cube renderer, hand-coding rotation, scaling, and translation without any built-in 3D support—pixel by pixel.
A hand-crafted Z80 routine and careful display-file arithmetic squeeze 64 columns of text onto screen using only BASIC and a hex-encoded machine code loader.
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.
Draw shapes and objects using a joystick and the keyboard.
A colourful, noisy joystick doodle pad for small children, complete with a bouncing cross cursor, random ink colours, and directional beeps for every move.
Draws a map of the United States, asks questions about capitals.
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.
Designed as an artists aid in creating computer art work. This program resembles MacDraw to some degree. Pix Fix gives
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.
A “99% complete” version of the program that was included in Volume 2.
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.
