AROS - a solid foundation

AROS is a complete NG OS based on AmigaOS 3.1 API. This means it includes many known components like datatypes (24bit), network stack, AHI, MUI-Implementation (Zune), USB-support, Themeing, window out of screen and RTG. The default desktop (Wanderer) is functional similar to old 3.1 workbench.

Additions

Addition there are Scalos and Magellan desktops. Both are highly configurable what I made extensive use of. Also Aros Vision is extended with additional commodities in WBStartup, handler and devices, libraries, commands in C and lots of software including many applictations, guis, games, demos.

Useable on both WinUAE and Apollo V4
