The Amiga’s Operating System (AmigaOS) has been around a long time and dates back to the release of the Amiga 1000 in 1985.
Many people have contributed to AmigaOS and you can see a (hopefully) complete list of those individuals here.
Special thanks goes out to Olaf Barthel for providing the initial list based on the actual source code commits. Recent contributions have come in from Robert “RJ” Mical and Bryce Nesbitt.
A lot of the source code has been changed and/or replaced over the years but many components and their original designs still live on in AmigaOS 4.1 to this day. Expect this list of credits to keep on growing.
