CATS Library Tape 2

Date: 198x
Type: Cassette
Platform(s): TS 2068

Volume 2 of the Capital Area Timex Sinclair Users Group (CATS) 2068 software library: 16 programs, mostly for drawing and graphics, with two educational programs at the start of the tape. It holds drawing programs for joystick and keyboard, chart and 3D routines, two banner printers for the TS2040, character and UDG editors, and a 64-column typing demonstration.

The download has a TAP of each program, text listings and screenshots, and a WAV recording of the tape. The list follows the order of the programs on the tape.

Programs on the Tape

  • Spanish Tutor: conjugates any regular Spanish verb you enter and teaches suffixes, opposites and question words (Martin Curley) (also #54556 Spanish Tutor)
  • Geography: a state-capitals quiz over a hand-drawn colour map of North America (also #54559 Geography Quiz)
  • Color Plot: a joystick drawing program with circle stamps, colour cycling, sound and tape save (also #50606 Color Plot)
  • Doodle: a noisy joystick doodle pad for small children, in random colours (John Riley) (also #64590 Doodle)
  • Spectrum Draw: a machine code drawing package from Your Computer converted to the TS2068, with circles, screen save and load and text (Floyd Chrysler) (also #64595 Spectrum Draw)
  • PixFix: a pixel editor with machine code for drawing, erasing, panning and saving whole or partial screens (John Nguyen) (also #64593 Pix Fix)
  • RandomFan: a fan of lines between opposite edges of the screen in random colours, drawn by its own line routine (also #64594 Random Fan)
  • PieChart: draws a pie chart, filling each wedge with dots at a density read from DATA (also #64592 PieChart)
  • 3D Shape: a wire-frame cube rotated, scaled and moved with 3D matrix arithmetic (Nick Hampshire) (also #64583 3D Shape)
  • BarChart: draws bars filled with dots at different densities, read from DATA (Nick Hampshire) (also #64586 Bar Chart)
  • Headline: prints large banner letters on the TS2040, each pixel of a character expanded into a block (also #64591 Headline)
  • Banner: prints an enlarged string on the TS2040, in normal or inverse, by reading the screen with POINT (also #64585 Banner)
  • Character Editor: design UDGs on an 8×8 grid with the byte values shown as you draw (also #64588 Character Editor)
  • UDG: a UDG editor for single characters, 16×16 sprites and large 23×24 sprites (George White) (also #64596 UDG Custom Graphics)
  • Characters: steps through the character set showing each character’s pixel grid and ROM bytes (also #64587 Characters)
  • 64 col: a typing demonstration in 64 columns: machine code switches the TS2068 into its 512-pixel display mode (OUT 255,14) and the BASIC draws each typed character into the display, with a caps toggle, inverse and delete

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.
