Long Island Sinclair Timex (LIST) User Group Library Tape #2.2

A compact 5-program supplement from the Long Island Sinclair Timex User Group, featuring a 3D Tic-Tac-Toe game, bold text, a Bézier curve tool, and two machine code utilities.

The tape is numbered 2.2 in the group’s library. Apart from the 3D tic-tac-toe game, all of the programs are short: bold, mcedit and mcloader are utilities for people working with machine code, and curve is a small BASIC graphics program. The same bold, mcedit and mcloader programs also appear on CATS Library Tape 3, and their pages on this site run the CATS copies.

Programs on the Tape

• 3D TIC-TAC: three-dimensional tic-tac-toe against the computer on a 3×3×3 board (front, middle and rear layers A, B and C), scoring as many three-in-a-row lines as possible (also #53785 3D Tic Tac Toe)
• bold: a short BASIC loader for a 29-byte machine code routine at 57786 that switches the screen to bold print (also #54521 BOLD)
• curve: asks for up to 20 corner points and plots the smooth Bézier curve they define (also #55005 Curve)
• mcedit: an eight-line memory editor that shows each address and its contents from a given start address and lets you type a new value or press ENTER to move on (also #54533 MCEDIT)
• mcloader: a machine code entry program that takes decimal bytes, POKEs them in below RAMTOP and checks them with a checksum (also #54534 MCLOADER)

The download has TAP, TZX and WAV files for each program. The mcloader.tap file in this download holds only the 19-byte program header and no program, so it will not load; the TZX and WAV copies of mcloader are direct recordings of the tape.
