As I retire, my goal is to share over 40 years of source code that I have written. I hope that others will find it useful or be able to learn from it. Here is a list of the different projects I have worked on, such as operating systems for various CPUs, debuggers, emulators, and utilities. Some notable projects include ARMOS, a multi process/task kernel for ARM; CUBIX, an operating system for the 6809 CPU; and DBOX, a Sony VCR controller. I have also developed tools for building my projects and various utilities for DOS. So, take a look and see if there’s anything that catches your interest!
