'''Microware Systems Corporation''' was an American software company based in [[Clive, Iowa]], that produced the [[OS-9]] [[Real-time computing|real-time]] [[operating system]].

Microware Systems Corporation existed as a separate entity from 1977 until September 2001, when it was bought by [[RadiSys|RadiSys Corp.]], and became a division of that company. The rights to Microware OS-9 and related software were purchased by a group of distributors on 1 March 2013. The new owner was Microware LP. Microware initially produced a version of [[BASIC programming language|BASIC]] and a real-time kernel for the [[Motorola 6800]] [[Central processing unit|processor]], and was asked by Motorola to develop what turned into [[BASIC09]] for the then-new [[Motorola 6809]] processor. Having written BASIC09, they decided it needed an operating system underlying it, and they created the first version of OS-9.

OS-9 was ported to the [[Motorola 68000 series|68000]] family of processors and, after being rewritten mostly in [[C (programming language)|C]], to the [[Intel]] [[x86|80x86]], [[PowerPC]], [[ARM architecture|ARM]], [[MIPS architecture|MIPS]], and some of the [[Hitachi]] [[SuperH]] (SH) series processors. Initially, in the days of the [[SS-50 bus]] and SS-50C [[Bus (computing)|bus]] systems such as [[SWTPC]], [[Gimix]], and [[Smoke Signal Broadcasting]], OS-9 was used more as a general purpose [[microcomputer]] operating system and had a large, active hobbyist-user population. OS-9 was also popular with industrial and embedded-system users. This was especially true when OS-9 was available for popular 6809-based computers such as the [[FM-7]], FM-77, and the [[Tandy Corporation|Tandy]] [[TRS-80 Color Computer]] and its near-clone, the [[Dragon 32/64|Dragon]]. Over time, Microware concentrated on industrial customers and neglected the hobbyist base that was porting a great many [[Unix]] packages and utilities to OS-9.
