I wrote this program one day while trying to figure out how to read the TS 1000 display file. The point of this program is to figure out what is on the screen at a particular print position. It’s a game of driving a jeep through a minefield. Use arrow keys to avoid the mines.
I thought about playing more with sound on the ZX81 or T/S 2068. The Zon X-81 and the T/S 2068 both use the AY-3-8910 Programmable Sound Generator (PSG) and they both interface with the PSG by using the PSG registers, so any sound settings will be usable on both. I tried the SOUND command on
Dr. Beep (Johan Koelman) has released 1K versions of two classic arcade games, Asteroids and Missile Command. These games are normal resolution games that fit in 1K (vs his Hi-Res 1K games).

While trolling the Internet, I came across the ROM file for the Memotech Memocalc expansion unit. I’m always a sucker for another Sinclair spreadsheet, so I downloaded the ROM file and the manual.
I have previously expressed my interest in using Sinclair computers for more serious work and not just playing games. I’ve been collecting any Sinclair related books that are more into the scientific side. While digging around the book archive of the “World of Spectrum” website, I found a couple of books that led me to
I’m not much into hardware, but I believe that things should be documented. After some discussions during the T/S group Zoom meetings, I thought I would see about documenting some ZX81 and T/S 1000 hardware aspects. On the Sinclair ZX World forums there is a fair bit of information about ZX81’s. Those folks are much

I’ve been using the tool ZXPaintyOne to create ZX81 graphics. The tool creates a long string of numbers to represent the value of the characters painted on the screen. I wrote zxpaintl.c to take the output of ZXPaintyOne and create a screen file (.scr) that could be directly loaded into the ZX81. I wrote zxpaint2.c
Sue Currier came from Australia to the United States to pursue a career in modeling. She was discovered by the Eileen Ford Agency in Melbourne. She flew to New York City to sign with them and worked with them from 1971 to 1974. In 1974, Sue married Ken Currier on the 86th floor Observation deck
I’ve been interested in dice mathematically for years. In wargaming, you win or lose based on the results of a 6-sided die. A role-playing game that I used to tinker with used multiple 6-sided die instead of multiple-sided dice. Back then I wanted to determine a percentile based on a two-die roll. I wrote a
Carlos Delhez, writer of Xtricator and Xtender ZX81 emulators, wrote a programming tool that provides an updated version of BASIC for the ZX81, Coral Basic Interpreter (CBI). CBI lets you enter BASIC programs without keyboard entry, meaning that all keywords need to be typed out.

n looking through the downloadable programs on timexsinclair.com, I found a memory scan program that provided a graphical view of the contents of memory. I thought I would try something similar for the ZX81.
