Downloadable Software for the ZX81, TS-1000 and TS-1500

Adapted from a similar game Fred Nachbaur had written earlier for the first TRS-80 Pocket Computer. This is a direct application of Greg Harder’s “SRAM Hi-Res Extended BASIC” (aka SHREB) that demonstrates just a few of the cool things you can do with this package. Runs in a standard 16K ZX81 or equivalent, plus 8K

Block Buster

Adapted from a Spectrum program, it is an interesting game in the “puzzle” genre.

Budgeter

Tracks actual vs. budgeted expenditures and computes the difference.

Calculator

Calendar

“Year-at-a-Glance” calculates any given year, showing the whole year on a single screen. Press “M” to give the “month” legends, “D” for day-of-the-week. Move the cursor around the calendar to highlight any date, then press ENTER – you’re shown your appointments or other significant events for that date. Move the cursor to a non-date field,

Fourier Analysis

Input the data points of any waveform (assumed repetitive) and it computes the Fourier transform. Or give it the transform (Fourier co-efficients) and it computes the wave. You can even do two independent waveforms, plotted X vs Y (such as Lissajous figures). Sample run contains such an X-Y plot in the shape of Mickey Mouse;

Gobble Man

You are chased around a maze by ghosts. If you can eat some magic food you have a chance of stopping the ghosts. This is a superb realization of this exciting game for the ZX81 and TS1000 computer. Written in machine code, with excellent graphics, there is also a personalized ‘high-score’. 16K.

Graphics Archiver

Store/ retrieve WRX16 graphics screens. “Upload” transfers existing high-res screen into program for saving, “Download” transfers from loaded program into high-res display file for viewing.

Hi-Res Chess

The classic Psion Chess game, with actual chess pieces on an actual board! Fred stretched Wilf’s routine to give 26 display rows… 24 for the board, and 2 for the input lines, so you have to key your moves in blind… not too much of a handicap, if you’ve played the original. To exit, press

Invaders

Fred Nachbaur’s Christmas present to his customers in 1987. This one’s claim to fame is that it used the SHREB package, but most of the program runs in machine-code, demonstrating that the SHREB package is a useful library of graphics routines as well as a BASIC extension. This program has a bug that’s so charming

L-Systems

L-Systems is a type of fractal using rules of generation to produce self-similar space-filling curves. This implementation by Greg Harder is true to the original specification, and it’s recommended that you look up the reference provided in the program. It uses a “QUIK” display mode, a hybrid between FAST and SLOW.

Macro-Life

Per Fred Nachbaur, “Greg Harder was a real master at adapting program listings in magazine into our High-Res BASIC environment. This Life simulation is an example. The zipfile contains both a 16K and a 32K version, the 32K version saves the screen in high memory for improved speed and more options.”

Mandelbrot-FPP

This is the classic Mandelbrot set fractal. The program is pretty much self-documenting, its claim to fame is the use of the ZX81’s calculator language directly, to give about a 3x speed increase over straight BASIC. However, it’s still pretty slow… be forewarned. MAND4-FP.P is a quadric Mandelbrot in medium-res dithered greyscale (needs 32K)

NIM 2K

A two-player Nim game for the 2K TS1000. Demonstrates what’s possible in just 2K of RAM, using only standard Sinclair BASIC. Because it uses the characteristics of the compressed display file, if you want to run it in a 16K ZX81 or emulator, you first have to POKE 16389, 72 then NEW before loading.

SRAM Hi-Res Extended BASIC

This is the full SHREB package, written by Fred Nachbaur and Greg Harder. Fred wrote the core routines (parser, tape routines, that sort of stuff) and Greg specialized in the cool graphics commands. Contains the latest version of the core only, plus a couple demos.

Voyage of Peril

Adapted by Greg Harder from a ZX81 program in a British magazine. It’s a cool little adventure game, that nicely shows off his SHREB sprites, among other things. Requires 32K of RAM, but no need to poke RAMTOP higher; it only uses high memory for data storage.
