Bitsy Bye is an example of highly efficient code: it runs in less than 1 kilobyte of RAM. The release includes Bitsy Bye, a menu-driven program launcher that allows for navigation through files on multiple floppy (or hacked USB) drives. You can test-drive ProDOS 2.4 in a Web-based emulator set up by computer historian Jason Scott on the Internet Archive. ProDOS 2.4, released on the 30th anniversary of the introduction of the Apple II GS, brings the enhanced operating system to even older Apple II systems, including the original Apple ][+ don't even support lower-case characters.
