At the end of 2000 I watched some GEOS-pages and asked myself, why not making such a system on CPC, too. Most CPCs have 128K (most C64 only have 64K), a screen-resolution of 320x200 with 4 colours (C64 only has 2 colours for each 8x8 area in 320x200) and some more advantages. So the idea of the SymbOS-Project was born. SymbOS stands for "SYmbiosis Multitasking Based Operating System". SymbOS should become a demonstration, what could be possible on CPC since the last 20 years. I want to give everything to SymbOS what a modern OS needs. Real preemptive Multitasking, a dynamic memory-management for up to 576K and more and a totaly MS-Windows-like GUI are the three most important things.
