Synchro-Sette April 1983

Cassette to accompany the April 1983 issue of Synchro-Sette, the monthly tape magazine for the TS1000 and ZX81 from The S & S Company. It holds a menu loader, seven programs and the month’s Bulletin Board. The loader marks the first four programs as 2K and the rest as 16K, matching the issue’s This Month’s Programs list.

The download has each program as a .tzx tape image with a .b81 text listing, in tape order, plus pictures.

Programs on the Tape

• LOAD4/83: menu loader. It keeps the program names in one comma-separated string, prints them with their 2K or 16K size, and loads the one whose number you press (9 loads the next program on the tape).
• LOGARITHMS: logarithm of any number to any base, using LN X/LN Y. (also #57568 Logarithms)
• GRAFIT: takes twelve months of sales figures and draws them as a bar chart, with the total and monthly average. (also #57569 Grafit)
• GUESS IT: two-player memory game: twelve pairs of block-graphic symbols hidden on a 6×8 grid, turned up two at a time by row and column. (also #57570 Guess It)
• PAINT BRUSH: screen drawing program: eight keys move a brush over the display file, S picks a new brush character, and K saves the picture to tape. (also #57571 Paint Brush)
• MEASUREMENT CONVERSION: converts between units of length, volume and weight from a numbered menu. (also #57572 Measurement Conversion)
• TORPEDO: fire torpedoes at a passing submarine with keys 1–5, with player names and a high score. (also #57573 Torpedo)
• SYNTEXT: Baby Syntext, a full-screen text editor with a help menu of SHIFT-key commands and saving of the text to tape. (also #57574 Baby Syntext)
• BULLETIN: the Synchro-Sette Bulletin Board for April 1983, an animated title followed by scrolling messages that are held in the program’s saved variables.

Content

Baby Syntext

Program

A surprisingly capable full-screen text editor stores 2,880 characters in a string array, with cursor movement, insert, delete, and tape save — all without machine code.

Grafit

Program

A 12-month sales bar chart that scales each row of block graphics to the highest value entered, then totals and averages your figures automatically.

Guess It

Program

A two-player Memory matching game on a 6×8 coordinate grid, hiding 12 pairs of block graphics behind inverse question marks until all 24 are found.

Logarithms

Program

A compact change-of-base logarithm calculator that accepts any base and number, then loops endlessly for repeated calculations using a neat RUN restart trick.

Measurement Conversion

Program

A 21-unit measurement converter spanning length, volume, and weight that uses a computed GOTO to jump directly to whichever conversion routine you need.

Paint Brush

Program

A keyboard-driven RAM editor that pokes a cursor character around the display file and lets you save your work — all in 16 lines of BASIC.

Torpedo

Program

A block-graphics submarine dodges across the screen while you fire angled torpedoes — but you only get 20 moves to sink as many as you can.
