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. I’m offering two programs this month. Sort of.  Actually they are very similar…

August’s Program: Cave War
August’s 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. It’s not where I want it and I’ve spent July working on my novel instead. That isn't to say that I’m going to leave July without a program of the month. Instead I’ve pulled from my original site to bring you one of my favorite programs, Block £ Spear…

June’s Program: Monster Maker
Okay I haven’t 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 June’s monthly program. It’s pretty straight forward and anti-climatic against the power of today’s 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 demo’s, 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 Z and . 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 it’s game over! How high of a score can you amass…

January’s Program: Fireball
January’s program of the month, Fireball, marks a first for me. Although I’ve used a few different methods to type in my programs, I’ve 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, I’m looking both forwards and backwards. Although I wrote SNUNCH in 1983, I added a corrected version to my first ZX81 web page in the ’90s. 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…

October’s Program: Space Dock
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. Though time has purg…

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 s…

September’s Program: S.M.P.
October’s 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…

Whoa, it’s August already? Time for another program of the month. Coming your way is Parachute, a deceptively simple reflex game that uses recognizable graphics to give you an enjoyable causal gaming diversion…

No Spaces for You
I wasn’t 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…

Updated Program Listing
Awhile back I went searching for a decent ZX81 font and ran across ZX81 VDU. I played around adding it to my site’s footer, but I really wanted to do more with it. It’s pretty good and, unlike some other fonts I found, it has all the ZX81 graphic characters…

ZX81 Retro Gaming
I often search around the web looking to see what kind of ZX81 community still thrives. I truly expected to find a community in decline, but a surprising number of nostalgia sites are still out there. I found some dedicated to hardware, some to emulating, and others to software…

July’s Program: Spiders & Flies
July is almost half over, but we still have time for our program of the month: Spiders & Flies. You play a growing Venus flytrap that is searching for flies and special bugs. Use the ZX81 arrow keys to move around: 5, 6, 7, and 8. But be careful…

June’s Program: Blast Off
Blast Off, June’s program of the month, is a simple game that tests your typing skills. You may find it a bit easier to play on an emulator than on a real ZX81. Fortunately, you can try now! It isn’t a very hard game if you are decent typist…

May’s Program: Up-Cake
Well it is getting late in the month and I didn’t want to pull another last-minute update. To make things a bit interesting, I used Zed Ex on my Android tablet to enter in this month’s entry. More on that in a bit. Let me first introduce our deliciously short entry for May: Up-Cake…

April’s Program: Star Dodge
Late and last-minute, I present April’s program of the month Star Dodge. A decidedly simple game that requires you to dodge stars randomly placed on the screen. Can you get your Tie Fighter shaped ship, an inverse H, past the increasingly more dense stars? Give it a try to see. Star Dodge doesn…

March’s Program: Raider V
In 1984, I moved that Summer from Italy back to the US. As I was Flipping through my old printouts, I ran across one that I had marked as the last program I completed In Italy. How cool is that? Seeing this, I just had to make Raider V my program of the month for March. I was a big fan of mechanize…

February’s Program: Enlarger
The old saying “time flies when you’re having fun” is so true of late. This year started with a bang and I feel like I’ve been running ever since. It isn’t that I haven’t wanted to work on my old ZX81 programs, but they often take a back burner to other past times…
