programming

UPDATE: I've released a new version with support for the Apple IIc and a Mono "green screen" mode

A few months ago, I released an initial version of a program I've always wanted to have. It's a programmers reference to the 65xx series of microprocessors, available now in iTunes store (it's free).

The code and presentation notes from my session at KansasFest 2013 are now available on GitHub. It's intended as a more modern introduction to programming the Apple IIgs, being mindful of the differences from its predecessors. https://github.com/digarok/gslib

The real meat-and-potatoes is in the "Crash Course.pdf" file. It's an extremely compressed explanation of building System 16 executables, ToolBox calls and how the video display works on the Apple IIgs.

Happy Holidays everyone. Here's my latest assembly demo for Apple II.

Sorry, that vid isn't very good, there are some sound synchronization issues due to the capture method via emulator... but you should run it on real hardware anyway, right? ;)
