Content

"BOLD" Character Subroutine

Program

A two-author machine code hack from 1985 that rewrites the system font in RAM to produce genuinely bold characters — toggled on or off at runtime with a single POKE.

2068 Art

Program

Two bouncing points trace 200 lines across the screen in an ever-changing geometric art display, then clear and restart with a new pattern.

Banner

Program

This banner generator reads ROM font bitmaps directly, decoding each bit to scale any message into giant printer text with adjustable width and height.

Beep

Program

A self-installing machine code beeper routine that carves its own RAM space, pokes 43 bytes of Z80, and plays a tone on every keypress via USR.

Binary

Program

Watch each bit light up in color as this educational tool converts any decimal number from 0 to 255 into its 8-bit binary representation, with an animated auto-demo mode.

Bounce

Program

Enter a bounce count and watch a pixel ricochet across the full screen, with distinct beeps at each wall — stopping exactly when you say.

Breakout

Program

A Breakout-style demolition game that drops a ball through coloured brick rows, complete with splash damage, a high score, and direct font manipulation for the scoreboard.

Calendar

Program

A calendar generator using Zeller's congruence calculates the correct starting weekday for any month from 1752 onward, with clever PEEK tricks to manage column-based layout.

Calligraphy Font

Program

A complete calligraphic bitmap font renderer that places custom 24×24 and 24×30 pixel letters anywhere on screen using pixel-precise coordinates and machine code.

Clip Art

Program

A ten-image clip-art menu lets you PLOT, DRAW, and CIRCLE flowers, bees, valentines, and more — even layering multiple images on one screen.

Clock

Program

A self-advancing digital clock that chimes every quarter-hour with distinct melodies and renders digits by bit-reading the ROM font with PEEK.

Code Mover

Program

A BASIC tool that relocates Z80 machine code to a new address and automatically patches every internal absolute address so nothing breaks.

Database

Program

A full seven-field contact database for a church department, driven by machine-code modules that patch RESTORE addresses on the fly to navigate records stored in DATA statements.

DigiClock 2

Program

A pure-BASIC precision clock uses nested timing loops, BEEP-based calibration, and indirect GO SUB calls via stored line numbers to display large block-graphic digits.

DISA-Z Disassembler

Program

A full Z80 disassembler in BASIC that decodes every prefix, resolves relative jump targets, and prints annotated mnemonics — with a single flag to switch between two character sets.

Disassymbl

Program

A BASIC-coded Z80 disassembler decodes opcodes from any memory address, handles CB and ED prefixes, and sends formatted mnemonics to both screen and printer.

figForth v1.0

Program

A complete fig-FORTH built specifically for the TS2068 — bank switching, Timex printer, extended memory and all — and released into the public domain.

Flight Planner

Program

A complete flight-planning calculator that plots your route over a hand-drawn map of the USA, computing wind correction, ground speed, and fuel burn for each leg.

Fort Worth Temp for December

Program

A hand-crafted Fort Worth December temperature chart plots record highs, record lows, historical averages, and a chosen year's daily readings — all with PLOT and DRAW.

FUDGE

Program

FUDGE is a complete joystick-driven UDG editor with pull-down menus, pixel grid editing, flip, rotate, shift, animate, and tape save/load for all 21 user-defined graphics.

Game Collection

Program

A seventeen-game collection packed into one BASIC program, with a single-keypress menu that dispatches players to puzzles, strategy games, and word challenges.

Header

Program

A machine code–assisted tool that intercepts and decodes tape header blocks, revealing file type, filename, length, and start address for any loaded tape.

Hydrology

Program

A menu-driven hydrology suite that calculates watershed slopes, draws drainage maps, prepares unit hydrographs, and fits lognormal distributions — all with embedded machine code.

Julian Day

Program

A two-way Julian Day Number converter that handles BC dates, century corrections, and day-of-week calculation via a clever shared subroutine.

KeyScan

Program

A tiny 25-byte machine code routine slots itself just above RAMTOP and returns real-time two-key keyboard state — callable from BASIC with a single USR expression.

Linear Optimization By Simplex Method

Program

A full Simplex Method solver that handles mixed constraints, artificial variables, and Big-M penalties — printing the complete tableau at every iteration until the optimal solution is found.

Machine Code Monitor

Program

A full machine code monitor lets you examine, edit, enter, save, and run memory—complete with hex/decimal toggle and Z80 scroll routines POKEd in at startup.

Mail List

Program

A complete tape-based mailing-list manager for a T/S user group, with member records, label printing, and a machine-code printer patch all bundled together.

Menu-Driven Grade Averaging

Program

A four-mode teacher's grade book that calculates weighted averages across a six-week period and prints formatted report cards directly to a 2040 printer.

Muzik Master

Program

A playable two-octave piano keyboard with flashing key animations, sharp/flat labels, and a built-in melody demo hidden behind a single keypress.

NPolygons

Program

Enter any number from 3 to 30 and watch every vertex pair of a regular polygon get connected, revealing intricate geometric star patterns built from pure BASIC trigonometry.

OSCAR-TEN

Program

A complete OSCAR-10 satellite tracker that plots world maps, calculates Doppler shifts, and displays live azimuth/elevation for 18 cities worldwide.

Pie Chart

Program

A fully interactive pie chart generator that pulls individual slices, labels them with trigonometry, and relies on TASWIDE for wide text output.

PSG Register

Program

An interactive PSG register editor that reads, displays, and writes all 15 sound chip registers live — showing binary and decimal values simultaneously.

Scramble

Program

Type in any 3–7 letter word and this BASIC program systematically generates every possible permutation, with factorial counts and real-time progress on screen.

Screen Layout Examination

Program

Enter any byte value and watch it fill every pixel and every colour cell on screen — a hands-on tool for understanding display memory layout.

Utility Bill Audit

Program

A complete household utility auditor that handles three-tier electric, gas, water, and shared phone bills — all driven by editable DATA statements.
