CATS Library Tape 3

Date: 1988
Type: Cassette
Platform(s): TS 2068

Volume 3 of the Capital Area Timex Sinclair Users Group (CATS) 2068 software library: 20 programs, most of them programming tools (hex and machine code loaders, a toolkit, BASIC extensions, memory and tape-header utilities) with a few household and hobby programs.

The download has a TAP and a TZX of each program, a text listing of each (.tap.txt), screenshots, a TZX of the whole tape and a WAV recording.

Content

Bank Reconciliation

Program

A two-mode checkbook reconciliation program prints formatted ledger columns on screen and paper simultaneously, using integer penny arithmetic to sidestep floating-point rounding errors.

BOLD

Program

A tiny machine code patch toggles bold, heavy-weight character output on and off with a single POKE to a system address.

CRYPTO

Program

A screen-based substitution cipher pad that lets you decode cryptograms letter-by-letter using the display buffer itself as its working data structure.

EXTENDED BASIC

Program

An interactive tutorial for a nine-command BASIC extension that hooks the error handler to add pixel-level sprite graphics, sound effects, and BREAK-key control via machine code.

FIRSTLOAD

Program

A Z80 machine code installer combines LDIR block-copy routines, a formatted memory inspector, and a region comparator into one compact loader utility.

FLIP

Program

A 118-byte machine code routine installs itself in high RAM, letting you flip the entire display upside-down or mirror it horizontally with a single RANDOMIZE USR call.

Formulary

Program

A complete darkroom reference program stores seven black-and-white film developer formulas with chemical weights and development times, all navigated from a single menu.

Geometric Patterns

Program

A geometric interference pattern builder that saves its own screen to tape with a user-chosen pause value baked right into the filename.

Headscan

Program

Decode what's on any cassette tape before you load it — this utility reveals file type, filename, length, and auto-start line by reading the raw header block.

HEXSPEC

Program

A hands-on hex loader that lets you POKE machine code directly into memory, with per-line checksum verification to catch any mistyped bytes.

INTERPOLATE

Program

A line-by-line interpolated graph builder that scales and plots any twelve data points with smooth linear interpolation between each pair.

Keyword (Kendall/Dohany)

Program

Lets Sinclair BASIC keywords be typed out in full, letter by letter, with a special cursor and on/off switching, from a 224-byte routine.

LISTS

Program

A fully configurable flat-file database lets you define custom fields, then add, edit, delete, search, sort, and save records — all from a simple numbered menu.

MCEDIT

Program

A compact memory editor lets you walk through RAM byte by byte, inspecting and patching machine code values interactively from the keyboard.

MCLOADER

Program

A machine code loader that POKEs decimal bytes into memory near RAMTOP, computes a checksum, and then tells you exactly how to SAVE the result to tape.

Sound Scanner

Program

Plug in audio, pick a graph style, and watch live waveforms appear on screen — this BASIC program samples your tape input using a custom machine code routine.

Tomorrow Lies In Ambush!

Program

A menu-driven word processor stores up to 600 lines of text with tape save/load, printer output, and a line-by-line editor — all in BASIC.

TOOLKIT

Program

A four-function BASIC toolkit offers machine code-powered renumbering, REM stripping, variable listing, and number compaction — all squeezed into a single two-part tape package.

Video Tape File

Program

A video tape catalog manager stores up to 100 titles with searchable subject and tape-number fields, complete with a Shell sort and tape-based data persistence.

Weekly Taping Schedule

Program

Enter your weekly recording schedule day by day and print a neatly formatted timetable complete with channel numbers and program names.

Note: Type-in program listings on this website use ZMAKEBAS notation for graphics characters.
