I’m entering the “Retro Challenge – Summer 2014” contest just for fun and to be motivated to finish a lot of projects I’ve had almost complete for some time now.

I’m going to try to post daily progress on a number of Apple II related projects. I’ll post a lot of code on my github site.  I’ll be trying to finish an iPad version of my 65xx CPU reference app.  There will be lots of demos, and maybe a game or two.  I might even go so far as to do my first PCB etching for a retro hardware project.  Stay tuned to this page for daily updates!!

*fingers crossed*

KansasFest 2010 redux – Apple II programming

Created using Javascript tracing tool.
Created using Javascript tracing tool. Exported to AppleSoft BASIC.

I have a bad habit of getting things 90% complete and then never finding the momentum for that last 10%. I did a presentation for the annual Apple II convention, KFest back in the summer of 2010. I also released a fairly buggy Apple IIgs game while I was there. I intended to fix some bugs in the game’s code and add a bunch of extras to my presentation package and then my life kind of went pear shaped. Now, over a year (and a missed KFest) later I decided I need to just put this stuff out, and move on with my life, and start some new Apple II projects. So I’m making this post which is a general collection of my presentation and game. It has my presentation notes, all of my presentation code, all of the code and assets for my game and a little info about it all.

Apple IIgs Fire Demo

I finally got around to hammering out a little demo to keep me warm on these cold winter nights.

The code is a bit of a mess but it was mostly a test to see if I could do it and pull off a convincing version of the classic Fire Effect so prevalent in 1990’s demos. It uses 16 bit registers and maybe a few 65816 opcodes but it should be pretty easy to port it to the IIe.
