I am also a Radio Shack Color Computer alumni, owe my career to it. I started using OS-9 as soon as I could afford to upgrade to 64K RAM, to which I thank feeling right at home with SunOS after I got access to that in the university. To anyone unfamiliar, which is probably most people, OS-9 was a multi-user multi-tasking operating system which ran on 6809 CPUs. While not a UNIX, it was similar enough that the transition to SunOS was smooth. To this day, I still alias "ls -la" to "dire", which comes from my muscle memory of typing "dir -e" in OS-9!
