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.

I decided as a birthday present to myself that I would finally get an older Apple II computer. I have a couple of old IIgs’es I play with regularly these days as well a IIc that was missing the power brick. I did the whole “items wanted” thing on Craigslist in hopes that someone nearby would sell me one on the cheap.

The first two replies were promising but their descriptions of the systems were a little vague and when I asked for more information I got no response. The third response sounded great: an Apple II+, Apple IIe and Apple IIc all with monitors and all “quite clean”. She was willing to let them go for $80. Not a great price and not a horrible price. Either way, I couldn’t get a deal like that through eBay because the shipping on the monitors alone would have to be at least $50.
