OS-9 is a Unix -like real time -, multiuser - multitasking - operating system .

It was originally in the 1980s by Microware for the 8-bit processor 6809 by Motorola developed. The system was further spread by porting it to the Motorola 68k architecture.

A further development was available for a while under the name OS-9000 for various other CPUs ( PowerPC , MIPS , SH3 / SH4 , XScale etc.), meanwhile only the name OS-9 is used for these too.

OS-9 was and is relatively widespread in control systems (mostly based on Motorola CPUs ) e.g. B. for image processing , but was also used where real-time, multitasking or multiuser properties were required, e.g. B. Telecommunications in the field of office automation.

The current open source project NitroOS-9, which is currently under development, is a completely new version that is compatible with OS-9 for 6809 and Hitachi 6309 processors, primarily for the home computers Tandy TRS-80 Color Computer , Dragon 32 and Dragon 64 with corresponding hardware requirements.

Application examples

• the Philips CD-i player uses e.g. B. Microware OS-9 Realtime
• the navigation system CARIN MK1 from Philips, uses OS-9 / 68K V2.4.0
• the navigation system of the BMW 7 Series ( E38 ), 5 Series ( E39 ) and 3 Series ( E46 ) uses OS-9
• former process control systems from IDS GmbH
• This operating system was also available for the Dragon 64 ( Dragon Data Ltd. , 8-bit home computer , 1982-84), there was also a good word processing program ( Stylograph ) and for the Tandy TRS-80 Color Computer 2
• a project for the Atari XL
• the sound sampler Fairlight CMI III (1985) was based on OS-9, the new Fairlight CMI OS-9.1 was based on OS-9.1
• the Bosch vehicle system analyzers (Bosch FSA) for workshops, etc. a. with a digital oscilloscope , use OS-9 with a 68k architecture
• the control of woodworking machines from the Homag Group
• OS-9 was available on the NDR small computer for the modules of the 68000 series
• OS-9 was also ported from Cumana to the ATARI ST series.
• on controls of EC screwdriving tools from APEX (formerly CooperTools) with the system designation MPro400
