January's Program: Hit Man
Another year, another month, and now another program to celebrate 2013. January’s program of the month is an old one: Hit Man. From 1983, Hit Man was my attempt at creating a wall dodging program and it is a tough one to play. Looking back, I probably should have made the walls a bit further apar…

December’s Program: Thyime
December is upon us and Thyime is the last program of the month for 2012. My how quick the year has passed. Thyime’s elements include moving, shooting, a break through wall, and a moving enemy. It does all this while remaining fast. Thyime provides a decent game to close out the year. I wrote Thy…

Bonkers! Redux
I couldn’t help it. I updated Bonkers using MCODER II to convert the BASIC code to Machine Language. This improved the speed of the game making improving its playability. If you haven’t played the 1985 version, play it first so you can appreciate the difference…

November’s Program: Bonkers!
November’s program is Bonkers! and it may drive you crazy! Simply use the ZX81 cursor keys to move your X around the field, avoiding the O’s and their trails. Can you survive, or will you go Bonkers? Okay, enough of the commercial, let’s talk about the program. Yes, it will drive you bonkers…

September’s Program: Runner
September’s program, Runner, is nostalgic for me. When I wrote this program I had moved on to my C64. My ZX81 was starting to gather dust as I was busy learning the ins and outs of my new computer. For some reason, something tugged at me to fix my ZX81 keyboard and get it running again…

August’s Program: PAC-MAN Video
Wow, August flew by way faster than I expected! Here we are at the end and I finally got around to uploading the monthly program. This month’s program, PAC-MAN Video, is a bit different. Although I call it a game, it doesn’t really play like one. It is totally random with a slight nod to you…

July’s Program: Can Punch
I’m back to the basics for July’s program. Can Punch is a simply graphic game that will probably infuriate you more than entertain. Don’t believe me? Go try it and decide for yourself. The goal is punch the can thrown at you. Use Z to raise your fist high and . to lower it…

June’s Program: Pole Dodge 2
Yes, I know I’m late. June is almost over and I’m sure my adoring fan is up in arms. I do have one fan, right? In any case, I’m breaking tradition for June’s Program of the Month and posting a more modern program. Pole Dodge 2 is my revamped version of April’s program…

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 “Z” and “.” keys to bank right or left. It isn’t an overly hard game…

April’s Program: Pole Dodge
Pole Dodge is April’s 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 doesn’t play well. I know that doesn’t lend well for one to give it a try, but try it you should. Why? Because the premise isn’t bad…

March’s Program: T.W.M.
T.W.M. is March’s program of the month. It is a simple animation that tries to mimic a computer’s 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 isn’t 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 January’s 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…

February’s 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 hadn’t guessed, it has its roots in Tron. The game requires you to steer right (“.”) or left (“z”) 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…

January’s 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 Z or . 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…

December’s Program: Creature
I can’t 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…

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

October’s Program: 1985
October’s 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…

September’s 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 gra…

August’s 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 isn’t that bad, but it definitely wasn’t one of better programs. This was from 1983, clearly one of my earlier attempts…
