I wanted to create some more electronic music to listen to while at work. Electric Shake is a simple ambient beat to relax to. As always, uploaded to my ACIDplanet.com site for our enjoyment.
I’ve been a bit busy this month so I choose a relatively short program in order to not miss my self imposed deadline. To that end, I present to you April’s belated graphic program: Sphere. This program will easily run on a 2K ZX81. With some trimming, if you are so inclined, it will probably run in the original 1K of RAM as well. Although I doubt too many people with a ZX81 have less than 16K of RAM. Take a look at the listing to get a feel for how small this program really is.
I geeked out a bit today by loading Ubuntu onto an old laptop that I’d been having problems running Windows on. Seems the issue was a bad hard drive as it started to slam the drive head against the stop during the first installation. I pulled a drive from another broken laptop to fix that problem and started over.
March’s program is Lock £ Fire. I wrote this graphic game in 1985, although I have to admit I don't remember it much. It is a bit hard to play as the keys aren’t very sensitive and the aliens jump around as you try to “lock” onto them. It doesn’t help that I used an odd keyboard layout which adds to the difficulty. The aliens are shooting at your shield and, if they get through, the game is over. Note that you don’t kill the aliens, but they may change their look. When you shoot them enough, the next level starts. Every 10 hits will clear some of your shields as well. Boy, I must have been in one of those moods when I wrote this.
For some time now I’ve listed the ZX81 books I own on my original ZX81 web site, but I hadn’t put much effort in searching the web for them. Mainly this was because I already own them, but mostly because it never occurred to me to do so. I ran across an online copy of Sinclair ZX81 BASIC Programming which made me wonder what other books existed out there. Sadly, my search uncovered very little legitimate books. However, World of Spectrum did have a good number of the books and cover art available.
It came to light that another Xbox 360 site is shuttering their doors: MyGamerCard.net. I was using an MGC gamer card on this site for years due to oddities with the official one from Xbox. I dropped it recently as I didn’t feel it was as important to my site anymore, but I really enjoyed the stats MGC provided and I stilled used my MGC userbar as a forum signature. Sad times indeed.
I was reading this article from Brickset about a scanned Bricks and Pieces No. 2 from Spring '75. It was an interesting read and a fun look into LEGO's past. I especially liked the "What is it?" article, a puzzle of instructions laid out in layers. I was pretty sure I knew what it was, but I just had to give it a go in LDD to verify. I was right, it was a Panda! Not content with just a simple screenshot, I exported it into POV-Ray. I think it came out very nicely.
Last night I happened to notice that my last blog post didn’t look quite right when viewed in an RSS reader. Come to find out, it appears that the code that converts the UBBC tags wasn’t undoing a quote conversion earlier in the code. This caused the regular expression that tries to show bare URLs as real URLs to convert parts of my image tag into an anchor tag. Not quite what it is supposed to do. It took me hours of futzing with the code to unravel the mess. Fortunately, it was an easy fix. Use the same darn subroutine that the articles use. Duh. One freaking line of code to change.
A few things have changed over the list eight years. As I wind down the use of my ZX81 site, incorporating it my main one, much of below is invalid. That doesn’t mean that changes weren’t important at the time. Ideas come and go, and it is good to remember where we came from. Below is a recap of what was.
I’ve added a new ZX81 Programs section that lists all of my ZX81 programs available so far. The list includes the name, a brief synopsis, and options to list or run the program as available. I still need to add a more complete description option. The code is there, I just haven't decided how I want to deal with the pictures. But hey, at least you can run every program I had available before, plus a few new ones.
