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. It was purchased by Radisys Corp in 2001, and was purchased again in 2013 by its current owner Microware LP.

Mac OS 9 is the ninth and final major release of Apple's classic Mac OS operating system, which was succeeded by Mac OS X 10.0 in 2001, starting the Mac OS X family of operating systems.

OS-9 ® is a full-featured operating system framework, including the OS kernel, kernel services, and industry-standard APIs, middleware, and a complete IDE-based development framework.

Jan 27, 2025 · OS-9 (or: OS9) – an operating system created in 1980 by Microware for computers based on the Motorola 6809 processor. It was purchased by Radisys Corp in 2001, and then sold in 2013 to Microware LP. The system was then implemented in 1983 on computers with processors from the Motorola 68000 family.

The OS-9 family of advanced software is not only more powerful than most other microcomputer scftware - it is also much easier to learn and use. Some of the advanced OS-9 features you'll learn about in this book are:

Nov 12, 2023 · Microware OS-9/6809. OS-9 was a multitasking operating system for the 6809 8-bit CPU. Level I was for systems without memory management and therefore both the OS and the user programs had to fit in 64 KB RAM. Level II gave an address space up to 2 MB.

OS9, OS-9, or OS 9 may refer to: Mac OS 9, an operating system for the Apple Macintosh; iOS 9, the ninth version of the iOS operating system; OS-9, a Unix-like real time operating system; OS/9, an operating system for the UNIVAC; OS9 (gene), which encodes protein OS-9 in humans

OS-9 is a versatile multiprogramming operating system designed to exploit the full capability of the Motorola M6809 Advanced 8-bit microprocessor. When used with the OS-9 family of software, the 6889 can deliver performance equivalent to a mid-size minicomputer.

Jan 19, 2024 · This book is not intended to contain a built-in OS course, rather to explain how the OS-9 system can be used in an application. All of the code examples are written in C (unless assembly is the only option), the current “language of choice” among the vast majority of real-time software engineers.

The purpose of this project is to provide an archive of material relating to the CoCo or OS-9. Back in 2004 it became apparent that CoCo and OS-9 information was disappearing rapidly, so a project was started to preserve as much information as is possible.
