Shoot the UFOs in This Simple ZX81 Game

Shoot the UFOs in This Simple ZX81 Game

Taking a minor departure this Memorial Weekend, my ZX81 program is actually from my childhood best friend. Neighbors during our time in Italy, Jeremy and I spent a lot of time together playing with our LEGO bricks, D&D, and on our computers. U.F.O is a simple shooter game that takes a unique approach to graphics.


The World Was Doomed And This Is The Result

The World Was Doomed And This Is The Result

The eighties were a turbulent time. Political turmoil grew out of the Cold War, which wasn’t loss on this teenage programmer. The vocal leaders of the US and the USSR bubbled up often in the pop culture of the era and the esclation of war. It shouldn’t be surprising that I’d create an animation depicting that escalation.

Enjoy 8bit Pylons? Yes, My ZX81 Game Has Plenty!

Here it is in July and I have another one of my dodging games to share. But, this one is a little bit different. You don’t need to dodge all of them, or in this case go through all of them. Nevertheless, if you want the juicy bonus points, you need to grab as many of the blocks as you can. The twist is how the pylons change as you play.



Look out for the Death Maze as You Escape the Monster

Look out for the Death Maze as You Escape the Monster

I seem to like avoid the wall games. I wrote many of them over the years, inspired by other games I played like “Cavern’s of Mars.” It isn’t a surprise as the ZX81 made it pretty easy to write a vertical scroller. For Death Maze, I added a little twist. Is it enough to make the game fun to play? Let’s find out.



Check out This Awesome Remake of Pole Dodge

Tower Dodge by Jim Gerrie, 2014

Jim notified me earlier this month that I’d missed one of his remakes of my ZX81 programs when I blogged about them earlier. Tower Dodge for the MC-10 is Jim’s version of my updated Pole Dodge 2. Not sure how I missed it as he rewrote it back in 2014. Of course, I can’t believe I wrote mine back in 2012! Time sure flies—get the pun? Anyway, let’s dive in and see what’s new.


Quick, Stop the Bomber before It Destroys You

Quick, Stop the Bomber before It Destroys You

Wait what? Another month? Another game? You betcha! April is upon us, and pretty much over. So, to pass the time I introduce Blaster, a shooter with a twist. Use Z to move left, . to move right, and M to fire. Not the most exciting game ever, but you’ll find it hard enough to spend a few minutes with it.



How to Make Digital Rain on Your ZX81

How to Make Digital Rain on Your ZX81

I’ve been wanting to create my own version of digital rain for some time. The effect is well known from the Matrix movies, which used florescent green characters. Inspired by that version, I decided to go retro and generate a black and white stream of characters using the ZX81. Let the geekiness begin.


Watch This Great Remake of Flywheel on the TRS-80

Fly Wheel by Jim Gerrie

While digging around my site’s SEO this morning, I ran across these great videos from Jim Gierrie. Both depict his remake of Flywheel on a a TRS-80 MC-10. He had shared in a comment on my site, but I’d missed it given how busy last year had been. I love that Jim took the concept and made it his own, exactly the purpose of this site.



What Can You Do with a Simple ZX81 Animation?

What Can You Do with a Simple ZX81 Animation?

Although may of my early programs were games, I spent a fair amount of time experimenting. December’s program, Slow Down, is one of my animation experiments. It is a straight forward sprite animation, with a twist. I used the ZX81 against itself to slow it down. If you’re ready, let’s dig deeper.



Windmill Is a Quick and Dirty ZX81 Animation

Windmill Is a Quick and Dirty ZX81 Animation

There are a ton of windmills in Idaho. Mostly big ones for power, but you see a few smaller ones used for irrigation and wells. But, when I wrote this month’s program, I couldn’t remember any being around where I lived in Indiana. No matter. I still wrote a simple windmill animation, and today is the day to share it.
