The 8bit multitasking operating system for the Amstrad CPC, MSX, Amstrad PCW and Enterprise 64/128.
SymbOS was originally started as an experiment to find out to what extent it is possible to implement a multitasking operating system with a windowed GUI on an 8-bit computer from 1985. GEOS contributed to the motivation, but the structure and features of SymbOS aren’t similar to that system. The release in 2006 proved that such a “mini windows” system is possible on a then 20-year-old home computer with only quantitative limitations. SymbOS is one of the largest retro computing software projects of recent years. One of the goals of the project is to allow these old machines to be used like a modern PC, using hardware extensions.
