Decemberís 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…

Augustís 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…

April has been a crazy month. I decided to try something new, pushed along by an unexpected event. Iím 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…

Marchís 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…

Winter has set in and it is time to close out the year with a simple game. Dollar Sign, Decemberís 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…

Novemberís 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 í90s. 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…

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.

Septemberís 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…

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…

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 siteís footer, but I really wanted to do more with it. Itís 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…
