If you ever get a chance to look through the classic Amiga OS source-code still floating around some murky corners of the internet, it is a thing of beauty and astonishing capabilities. It’s an inspirational piece of computing history with unmatched capabilities for the time. Remember, this was all on a computer released in the 1980s with 512Kb memory, a 7Mhz 68000 16-bit CPU, and a single floppy drive with 880Kb storage. On these limited specs, AmigaOS provided a pre-emptive multi-tasking operating system, a full set of GUI primatives and built-in “Workbench” interface, expansion card auto-configuration and a fully-featured filesystem with some unique and powerful capabilities.
