A later 6809 version ("Level Two") takes advantage of memory mapping hardware, supported up to 2 MB of memory (ca. It was developed as a supporting operating system for the BASIC09 project, contracted for by Motorola as part of the 6809 development. The first version ("OS-9 Level One"), which dates back to 1979–1980, was written in assembly language for the Motorola 6809 CPU, and all of its processes ran within the 64KB address space of the CPU without a memory management unit. Today, OS-9 is a product name used by both a Motorola 68000-series machine language OS and a portable ( PowerPC, x86, ARM, MIPS, SH4, etc.) version written in C, originally known as OS-9000. The OS-9 family was popular for general-purpose computing and remains in use in commercial embedded systems and amongst hobbyists. It was purchased by Radisys Corp in 2001, and was purchased again in 2013 by its current owner Microware LP. OS-9 is a family of real-time, process-based, multitasking, multi-user operating systems, developed in the 1980s, originally by Microware Systems Corporation for the Motorola 6809 microprocessor. Motorola 6809, Motorola 680x0 CPUs, ColdFire, SuperH, ARM/XScale, MIPS, PowerPC, Intel x86 architectureĬLI in all versions, some platforms support a GUI High-performance, high-availability real-time software solution for advanced industrial automation & control, medical instrumentation, aerospace and transportation systems
