Things I've written for Commodore computers
The lion share of my earlier production of Commodore 64 software is available in my old PD library, SYS PD/C64,C128, which is available in its entirety on the Internet. These are software I wrote back in the times when the Commodore 64 was my main computer, before PCs entered my life (and ruined it for all time, or something). It is mainly serious software, like the BASIC lister Programläs and account manager Databudget, programs I actively used myself. Please note that regardless of what is written in connection to the programs I have written myself they are now licensed according to the GNU General Public License version 2.
Early 21st century, my interest in Commodore software was once again brought to life, partly due to the Minigame competition 2002, where the task was to write a game no larger than 1024 byte. I've never really been very good at writing games, but I did submit three entries anyway, all written in BASIC. One program is for the Commodore 128 in 80 column mode, one for said computer in 40 column mode and the third an extremely simple program that worked on all Commodore computers with BASIC 2.
For the first time I also took part in a demo party (albeit a small one) during October 2002, where I made some fonts (and wrote scroll text) for Laconic. I also attended the Creators November party 2003, where I did much the same things.
The Minigame competition returned in 2003, where there also was a category for games of up to 4096 bytes. I submitted these two entries, where the first was my adventure game “The Potion”, which I originally wrote for the 2002 competition, but which got way too large, even though I had written extremely short room descriptions. I dusted the game, which is now rewritten in C (with some routines in assembly to keep the size down), off. The full version did not fit in 4K even when compressed, but a version with slightly abbreviated descriptions did fit. The other game is a 1K game in C128 BASIC, a sequel to the mathematics puzzle of last year.
I have written a few utilities that run on non-Commodore machines that are related to the Commodores. Among them are converter software to convert from some Commodore 64 bitmap formats into generic image file formats that can be converted to more useful formats for further processing.
All these programs are released according to the licensing terms described in Free Software Foundation's software license GNU General Public License. Because of this they are free software, free in the sense that they give the recipient freedom to examine how the program is built themselves and learn from it. My programs might not be the best ones to learn stuff from, but you never know. Some people have started calling this phenomena open source. This is mainly for people afraid of freedom, but that still want the source available. Since I like freedom, I call it free software.
