Graphical Z80 Multitasking Operation System
SYmbiosis Multitasking Based Operating System (SymbOS) is a multitasking operating system for Zilog Z80-based 8-bit computer systems. Unlike early 8-bit operating systems, SymbOS is based on a microkernel, which provides preemptive and priority-oriented multitasking and manages random-access memory (RAM) with a size of up to 1024 KB. It has a Windows-like graphical user interface (GUI), supports hard disks with a capacity of up to 128 GB and can already be booted on an unexpanded Amstrad CPC-6128, a 128K-MSX2 and an Amstrad PCW.
SymbOS is available for the complete Amstrad CPC 464/664/6128 range (old and new generation), for the MSX1 (+V9990), MSX2, MSX2+ and MSX TurboR machines, for all Amstrad PCW models of the 8xxx, 9xxx and 10 series and for the Enterprise 64/128 machines.
