May's Program: Jet Flyer
Jet Flyer is May's Program of the Month. Although a bit late, I believe it is a bit better than last month's and worth a quick try. The goal is to keep your jet on course by using the ďZĒ and ď.Ē keys to bank right or left. It isnít an overly hard game…

Aprilís Program: Pole Dodge
Pole Dodge is Aprilís Program of the Month and it is an odd one. Partially odd because I typed it in back in February, and partly because the program just doesnít play well. I know that doesnít lend well for one to give it a try, but try it you should. Why? Because the premise isnít bad…

Marchís Program: T.W.M.
T.W.M. is Marchís program of the month. It is a simple animation that tries to mimic a computerís destruction of its defined target. February was actually pretty prolific for me as I transcribed this and another program, as well as updated a number of older programs using MCODER…

E.T. Redux
E.T. may not have been my best game ever, but it was an interesting exercise in 1985. Loosely, and I really mean loosely, based on the Atari 2600 game, E.T. follows the exploits of the title character as he tries to find his way home. Originally written in ZX81 BASIC, I revisited E.T…

Playing Around
It isnít all programming around here! Some days it is fun to just play around. I was adding an image to my other site which led to me reviewing some of my old Flickr images. In turn, I ran across my Wordle of Reid's for Fun image (article here)…

Road Hog Improved
What's this, another version of Road Hog? Yep. This is Januaryís Program converted to machine code using MCoder II. I was surprised how easy it was. Although MCoder is an integer compiler and limits some BASIC commands, I only needed to change a few lines to get Road Hog to run…

Februaryís Program: Light Walls
February is upon us and that means another program of the month. This month it is another one from 1983: Light Walls. In case you hadnít guessed, it has its roots in Tron. The game requires you to steer right (ď.Ē) or left (ďzĒ) to avoid hitting the light walls…

ZX81 Emulator on Android
As more and more people turn to mobile and tablet devices for their entertainment and consumption needs, it is becoming harder to share my ZX81 preservation project. I remember how excited I was when I found a Java based emulator that would run my ZX81 programs on the web…

Januaryís Program: Road Hog
Welcome to the new year! Starting off the second season of monthly programs is January's program Road Hog. Road Hog is a driving game similar to my later Flywheel game. I hesitate to call it a racing game as there is no acceleration. You just move the car left or right using the ďzĒ or ď.Ē keys…

A New Year of ZX81 Programs
Well, the celebration of thirty years since the introduction of the ZX81 is now over. For the last year I've been bringing you an original ZX81 program each month as a tribute to my first computer…

Decemberís Program: Creature
I canít believe December is here and the year is almost over. To celebrate the last program of the month, I present Creature, an animation program. Unlike many of the smaller programs submitted throughout the year, this one is the largest weighing in at 14KB…

Hacking Up RSS
When I first created my re-visioned ZX81 site, my goal was to integrate it as a sub-site of my existing one. However, the CMS I use doesn't lend itself to easily do that. Technically, that wasn't a show stopper in and of itself…

Novemberís Program: Lander 2
November is here and the year is flying by. This monthís program Lander 2 is an earlier one from 1983. Oddly, the game displays Space Lander. Not very original as Iíve used that name before. Iím using the name I noted in my listing. Although it has graphical elements, it is really just a counting g…

Octoberís Program: 1985
Octoberís program is one of my later games from 1985 which is aptly named 1985. It has decidedly simple game mechanics. Set in an alternative reality, the Earth is gone in this version of 1985. Humans are colonizing Earth II, but you need to clear the mountains for agriculture needs…

Septemberís Program: Odyssey
This month I present another simple game, Odyssey. It doesn't include instructions, so here is a quick synopsis. An evil computer has trapped you in a space ship. To escape, you have to remove the memory boards in order to shut down the computer. Sounds familiar…

Space Lander 2011
I couldn't leave well enough alone. All that analyzing and nitpicking of the original Space Lander made me wonder what it might be like if I had rewritten it. Almost 28 years later, here is the reborn version of Space Lander 2011. I tried to stay true to the original, keeping most of the key graph…

Augustís Program: Space Lander
Okay, this may not be the large program I promised, but I choose Space Lander for a different reason: it's horrible! Okay, maybe it isnít that bad, but it definitely wasnít one of better programs. This was from 1983, clearly one of my earlier attempts…

Julyís Program: Sugar Cube Munch
Another simple program. Like many that I wrote for the ZX81, Sugar Cube Munch was small with a singular purpose. In this case, the goal is to eat all the cubes of sugar as quickly as possible. Once all the sugar is eaten, the game is over and the number of turns is revealed…

Juneís Program: Beo One
I was searching through my stack of programs and decided to choose a short and sweet program for June. Beo One is definitely short, clocking at just 33 lines of code. Well 35 if you include the two new save and run lines I added…

Aprilís Program: Sphere
Iíve been a bit busy this month so I choose a relatively short program in order to not miss my self imposed deadline. To that end, I present to you Aprilís belated graphic program: Sphere. This program will easily run on a 2K ZX81…

Marchís Program: Lock £ Fire
Marchís program is Lock £ Fire. I wrote this graphic game in 1985, although I have to admit I don't remember it much. It is a bit hard to play as the keys arenít very sensitive and the aliens jump around as you try to ďlockĒ onto them…

Digging for Old Books
For some time now I've listed the ZX81 books I own on my original ZX81 web site, but I hadn't put much effort in searching the web for them. Mainly this was because I already own them, but mostly because it never occurred to me to do so…

Februaryís Program: Golf
This monthís program is a simple game of Golf. Although not overly exciting, it does show off a few ZX81 BASIC features. One oddity of the ZX81 is that π (pi) is built in, something I havenít seen in other languages. In this case, it is used to calculate the direction of the golf ball…

Major ZX81 Updates
A few things have changed over the list eight years. As I wind down the use of my ZX81 site, incorporating it my main one, much of below is invalid. That doesnít mean that changes werenít important at the time. Ideas come and go, and it is good to remember where we came from…

New ZX81 Programs Section
Iíve added a new ZX81 Programs section that lists all of my ZX81 programs available so far. The list includes the name, a brief synopsis, and options to list or run the program as available. I still need to add a more complete description option…
