A 24-program collection from the Capital Area Timex Sinclair User Group emphasizing Z80 development tools, databases, and technical utilities.

Content

2068 Assembler

Program

A table-driven Z80 assembler written entirely in BASIC supports the full instruction set, symbol tables, forward references, and optional tape-based source merging.

2068 Disassembler and Monitor

Program

A full Z80 disassembler and machine code monitor that decodes every opcode prefix, supports symbol tables loaded from tape, and outputs to screen or printer.

Attr Table

Program

A handy on-screen reference table renders all 64 paper and ink color combinations, showing their attribute byte values styled in the actual colors they represent.

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.

Caloriburn

Program

Enter an activity number and exercise duration to instantly calculate calories burned and the equivalent weight loss in both kilograms and pounds.

Cassette Label

Program

Enter two tape titles and this program prints a ready-to-fold cassette case label complete with cut lines, fold guides, and fitting instructions.

Circuit Sketch

Program

Draw complete electronic circuit diagrams interactively, placing resistors, capacitors, transistors, diodes, and more using simple single-key commands.

Copycat

Program

A tape copier and Z80 assembler in one package — copy tapes with or without headers, and assemble Z80 machine code with full instruction set support, symbol table, and forward reference resolution.

FILE 1

Program

A complete menu-driven database system lets you design custom record layouts, sort, search, edit, and archive data to tape using embedded machine code routines.

GRID 9X

Program

A BASIC program that draws a precision 24×24 pixel grid with registration marks and tick decorations, then sends it to a printer for graphics design work.

HEXLOADER

Program

Enter hex bytes directly into memory with automatic address tracking, running checksum management, and a review mode that reads back every POKEd location.

MC-MOVE

Program

A BASIC-driven Z80 machine code relocator that rewrites embedded 16-bit addresses opcode-by-opcode, letting you move assembled routines to a new memory location safely.

Metric Conversion

Program

A 17-category imperial-to-metric converter that uses a compact comma-delimited factor string and a computed GO TO dispatch table to handle everything from teaspoons to tons.

Multi Tape

Program

A tape cataloging utility that POKEs machine code to read raw cassette headers and stores up to 400 program entries across searchable arrays.

MULTIFILE+

Program

A full-featured string database manager with Quicksort, multi-field search, record deletion, and tape save — all packed into a single BASIC program.

RESISTOR

Program

Dial in any four-band resistor's color code with this interactive decoder that calculates resistance, preferred E12 values, and tolerance in real time.

SEND VARS

Program

A modem utility that hides and restores BASIC variables and machine code by embedding callable routines directly inside a REM statement for over-the-wire transfer.

Sound Effects

Program

A six-option sound demo lets you trigger bomb, gunshot, and explosion effects, play "America the Beautiful," or perform on a fully interactive on-screen piano keyboard.

Streams and Channels

Program

Peek inside the streams and channels tables live in RAM — this diagnostic tool decodes every address, routine pointer, and device specifier byte on screen.

Telephone Directory

Program

A full-featured telephone directory application with interactive entry, alphabetical bubble sort, substring search, and hardcopy printing — all in BASIC.

TRACER

Program

A BASIC flow tracer that injects Z80 machine code to walk your program's GOTO, GOSUB, and IF…THEN branches, displaying the full execution path line by line.

Tracer

Program

A merge-in BASIC flow tracer uses embedded Z80 machine code to walk your program's control flow, printing every GOTO, GOSUB, and RETURN it encounters.

Unifile III

Program

A surprisingly capable flat-file database packed into BASIC, using a 28,000-character buffer, binary search insertion, and live record compaction on delete.

Varslist

Program

A 173-byte machine code utility reveals every BASIC variable currently in memory — just call it with RANDOMIZE USR to inspect your program's state.
