May's Program: WIZERDRY
Okay, you may be wondering why there is a picture of an Apple II on a ZX81 site? I’ll start by saying that it’s been a pretty busy May with lots of travel for both business and vacation…

April's Program: RMS
Are there any D&D folks in the audience? Come on, you know who you are. Past or present doesnít matter, just if you know what Iím talking about. Why, you ask? Because RMS, Aprilís program of the month, will use your ZX81 to build monsters…

March's Program: Input One
Input One, March’s program of the month, is a great example of the kind of simple and brute force programming of the 1980s. This was a time when computers had little memory and their users had to use simple BASIC programming to get things done…

February's Program: Math Bash
At the one level, you can sum up most programs into three big groups: business, gaming, or educational. Most of my programs fit into one of these base categories. The standouts are generally the animation or demo programs that really have no distinct genre…

January's Program: Comp. Talk
Mixing things up a bit, I thought Iíd start off the new year without a game program. Instead, Januaryís program is Computer Talk, or Comp. Talk for short. Comp. Talk is one of several educational programs I wrote for reasons Iím not entirely sure of. Perhaps it was just the thing to do back in then…

December's Program: V Water Battle
As 2014 comes to a close, I wanted to end the year with an original program of the month. For December, that program is V Water Battle, an action game from 1984. For some reason, the title screen I created said designed instead of wrote but I did both. I was an odd duck in 1984…

Hope everyone in the US had a great Turkey Day (Thanksgiving) and are now enjoying the last weekend of November. I’m busy with NaNoWriMo, and a bit behind. So I give you another program from my original ZX81 site, but not yet featured here. November’s program is the month is Maze Craze…

October's Program: NA
Whoa, there are still almost two weeks left in the month and I have October’s program done and waiting for you. Yep, you heard right. This month is a short one called NA. The program is an action game that requires you to use “N” and “A” to try to stop a runner…

September's Programs: Photon '85 and '98
Well, the month is over and life has taken over and delayed my program of the month. For the tail end of September, I offer two programs: Photon and Photon 98. Wait, what? Yep, you heard right. Iím offering two programs this month. Sort of.† Actually they are very similar…

August's Program: Cave War
Augustís program is Cave War, a later program from 1985. It starts out similar to Hit Man, basically a scrolling dodge the wall game. But there is more to it than that. Once you get to the end of the tunnel, you find yourself in a cave and need to blast away at a wall to continue on…

July's Program: Block £ Spear
Sorry, still no Joust. Itís not where I want it†and Iíve spent July working on my novel instead. That isn't to say that Iím going to leave July without a program of the month. Instead Iíve pulled from my original site to bring you one of my favorite programs, Block £ Spear…

June's Program: Monster Maker
Okay I havenít finished my remake of Joust yet, nor did I want to wait until the last week of the month to get an article out. Instead, I offer you Monster Maker as Juneís monthly program. Itís pretty straight forward and anti-climatic against the power of todayís programs…

May's Program: Joust
I actually started working on May’s program of the month, Joust, about three weeks ago. My goal was to update the program to a faster and more fluid MCODER version. Sadly, things haven’t gone so well…

April's Program: Flywheel
April has been a crazy month. I decided to try something new, pushed along by an unexpected event. I'm writing a book. I joined NaNoWriMo just after last November's event so I didn't expect to do anything until later this year. The surprise was their CampNaNoWriMo event in April…

March's Program: The Ball Redux
For March's program of the month, I drew inspiration from one of my older demoís, The Ball. Like many young kids from the early eighties using BASIC, I took a stab at animating a bouncing ball. It is a a relatively easy program to write depending on how complex you want to make the math…

February's Program: Time
For February, I give you Time, a simple landing game with a twist. Using the ďZĒ and ď.Ē keys, you maneuver your craft to each successive landing pad. If you miss the landing, keep trying but be careful. Run out of time and itís game over! How high of a score can you amass…

January's Program: Fireball
Januaryís program of the month, Fireball, marks a first for me. Although Iíve used a few different methods to type in my programs, Iíve always gone back to a Windows so I could use EightyOne to generate the program files and images…

December's Program: Dollar Sign
Winter has set in and it is time to close out the year with a simple game. Dollar Sign, December’s program of the month, is that game. All you need to do is move your character, which surprisingly looks like a dollar sign, into the inverse, dare I say it, dollar sign…

November's Program: SNUNCH ML
For November, Iím looking both forwards and backwards. Although I wrote SNUNCH in 1983, I added a corrected version to my first ZX81 web page in the Ď90s. SNUNCH was my early attempt at writing a PAC-MAN like game. Note that I said like, not clone. My goal was to be inspired, not to copy…

Since it's been a few months since I've presented an animation program, I hereby offer October's program of the month Space Dock. Written when the space shuttle program was in full swing, Space Dock depicts a shuttle launch for its scheduled docking to repair a satellite…

Doing Some Fall Cleaning
I took a break from educating myself on z80 machine code, more on that later, to fix a few things that have bugged me about the site. They are minor and probably will go completely unnoticed by most, but I wanted to make a quick note for future reference. Hey that’s what blogs are for, right? I…

September's Program: S.M.P.
Octoberís program of the month is S.M.P. or Sinclair Memo Pad. A simple scrolling editor that allows you to take a couple of quick notes that last as long they are on-screen. Since the space key also acts as a break, which will stop the program, S.M.P. uses the newline key instead…

ZX81 Nixie Clock
While searching for some code examples I ran across this inventive hardware expansion. Michel created a ZX81 Nixie Clock and has been kind enough to share his creation with the world through Facebook. Okay, silly me had no idea what a Nixie was…

No Spaces for You
I wasnít sure in my last post how to remove the extra space from the program listings. Well, I figured it out. It was surprisingly easy and took me about five minutes of searching and updating. Apparently there is a CSS property called line-height. Set it to one and problem solved…
