Jane 128 was a GUI-based integrated software package for the Commodore 128 personal computer developed by Arktronics and released by Commodore International in 1985. Like Commodore's earlier Magic Desk software, and somewhat typically for "user-friendly" software of the era, it used a literal desktop metaphor with the interface consisting of an onscreen graphic of a desktop with icons representing associated business tools - a typewriter represented the word processor component, a filing cabinet the database and so on. It was designed to be controlled by either a joystick or a mouse. It was not a success in the marketplace but represented an early example of a graphical interface on an 8-bit computer.
Arktronics was a software development company in Ann Arbor, Michigan. Jane was originally intended to be a package not only for the Commodore line, but also for the Apple, Atari, and others. This transportability was engineered by a combination of higher level systems written in the C language and machine specific drivers written in the assembly language for each machine. Jane was originally developed for the Commodore 64 within the Commodore line.
