Retro Challenge – Summer 2014

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*

Apple II Game – Flapple Bird

Flapple Bird for the Apple IIe

A while back, there was a post on a popular internet forum for retro computing about Flappy Bird. You know, that game that went viral and subsequently got pulled by the author. Anyway, it turns out that people had made versions for pretty much every old 8-bit computer under the sun… except one. There was no Flappy Bird for the Apple II! This upset me. The Apple II was and is extremely popular. We couldn’t let ourselves be so underrepresented. I decided to take action.

 

UPDATE: I’ve released a new version with support for the Apple IIc and a Mono “green screen” mode

And now for something completely different – JOYSTICKS!

My first fully assembled model.

I have always wanted a thumbstick for Apple II gaming. It’s the form factor we are all more accustomed to these days. Also, Apple II joysticks on eBay are typically overpriced and who knows how much wear-and-tear they already have on them. So I finally got around to learning some practical electronics to build my own. I ordered some thumbsticks, capacitors, resitors, potentiometers and buttons and using some online resources, built my own joystick!

KansasFest 2010 redux – Apple II programming

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.

KFest ’08 Redux

For those who don’t know (99.999% of the population) KansasFest (a.k.a. KFest) is a yearly Apple Computer themed conference that takes place in Kansas City, Missouri. When I say Apple, I mean Apple II. There are the occasional Mac/iPhone topics but really who cares about that? I went in 1993 which was probably close to the last big one, when Apple Computer was still sending employees.

I honestly had no idea it was still going on until I found out from an old friend in 2007 that indeed they still were holding it every year. I decided that not only would I go, but I would present NEW Apple II software! Indeed, I made it, albeit only for part of the sessions and I didn’t really finish my software on time but it was still wholly worthwhile for an old nerd like me.
