Editing OS-9 (section)

==Status==
OS-9 has faded from popular use, though Microware LP does still support it and it does run on modern architectures such as ARM and x86.  The compiler provided, Ultra C/C++, supports [[C89 (C version)|C89]], but supports neither [[C99]] nor [[C++98]].  Ultra C++ does provide limited support for C++ templates. It is also supported by popular [[Transport Layer Security|SSL/TLS]] libraries such as [[openSSL]] and [[OpenSSH]]. Recently CLANG/LLVM has been ported to OS-9 for PPC & ARM architecture CPU's.  
* A Version of OS-9 running Steve Adams' G-Windows is present on semiconductor wafer scrubbers manufactured by Ontrak Systems / Lam Research. Thousands of these systems are in use today, however, the software running on them dates to 1999 when the last version was created to handle Y2K issues. 
* Versions of OS-9/68K ran on a wide variety of [[68000 family]] platforms, including the [[X68000]] in Japan, some personal computers intended by their designers as upgrades from the Color Computer (e.g., the 68070 and [[MC68340|68340]]-based MM/1, and on other computers from [[Frank Hogg Laboratories]], PEP Modular Computers, and Delmar Co.) It was also ported to the [[Atari ST]] by Recc-o-ware in the early 1990s, and was distributed by Cumana in Europe.  A port for 68000-based [[Apple Macintosh]]es distributed by Ultrascience exists. A port to the [[Amiga]] by Digby Tarvin is also purported to exist.
* OS-9/68K is mandated by [[California Department of Transportation|Caltrans]] to be used in the 2070-1B and 2070-1E controller cards, and so ends up being used to run many North American traffic signal control systems.
* OS-9/68K is also found in some other embedded applications, including the Quanta Delta television broadcast character generator, still in production by [[ScanLine Technologies]] in Utah.  While the user-level interface code on this system started at boot time, there was a hidden, undocumented keyboard sequence that would provide a user with a root shell prompt in a scroll window on the device's edit-channel monitor.
* In the embedded market, where OS-9 has found application in such devices as the [[Fairlight CMI]] synthesizers, robotics, in-car navigation systems, and [[Philips]]' Compact Disc-Interactive ([[CD-i]]) industry standard.
* The [[TRS-80 Color Computer]] (and clones) still has users and an annual conference in Chicago; as of 2018 the 27th Annual "Last" Chicago CoCoFEST<ref>[http://www.cocopedia.com/wiki/index.php/Chicago_CoCoFEST! CoCoFEST]</ref> was scheduled for April 21–22, 2018. A group of Canadian programmers rewrote OS-9/6809 Level II for the CoCo 3 (w/ address translation hardware) for efficiency, and to take advantage of the [[Hitachi_6309#Computational_efficiency|native mode of the Hitachi 6309]]. Today's serious CoCo users now typically have replaced the 68B09E in the CoCo 3 with an Hitachi 63B09E and run the rewrite, called [[NitrOS-9]]. The combination is surprisingly fast, considering that it runs on an expressly low cost, 8-bit computer system.
* Gary Becker's CoCo3 FPGA is a synthesized TRS-80 Color Computer which runs NitrOS-9 on an Altera DE-1 development board.  The core 6809 CPU was designed by John Kent and is currently running at 25&nbsp;MHz.
* OS-9000/80x86 can be run on PC-type machines built around the Intel x86 CPUs. OS-9000 has also been ported to the [[PowerPC]], [[MIPS architecture|MIPS]], some versions of [[Advanced RISC Machines]]' [[ARM architecture|ARM]] processor, and some of the [[SuperH|Hitachi SH family]] of processors.
* The [https://web.archive.org/web/20060614173918/http://www.360systems.com/docs/prod_dcplus_main.html DigiCart/II Plus] audio playback unit runs OS-9/68K. It is a solid state replacement for radio station style [[8-track cartridge|cart]] players. These units are used in radio and at places like Walt Disney World where they play park announcements.
* German electronics manufacturer [[Eltec]] has been manufacturing the Eurocom-model CPU boards for industrial purposes since the late 1970s, starting with the [[6802]] and [[6809]] [[Eurocom-1]] and [[Eurocom-2]], and onwards with 68K, and derivative, CPU boards up to today. The modern boards can be delivered with a range of operating systems, amongst which is OS-9.
*[[Omron]] used OS-9 in their NS series HMI panels. However, for their new NA series, Omron selected [[Windows Embedded Compact 7]]. Omron indicated that with OS-9 nearly all the drivers, for example for a USB stick, had to be written by Omron.<ref>{{Cite web |url=https://www.support-omron.fr/telechargements/documentations/2017-11-14%20-%2010-11-58%20-%201760282707/NA%20Training%20Book%20v2.4.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.support-omron.fr/telechargements/documentations/2017-11-14%20-%2010-11-58%20-%201760282707/NA%20Training%20Book%20v2.4.pdf |archive-date=October 9, 2022 |url-status=live |title=NA Training Book 2.4 |website=industrial.omron.eu/NA |access-date=March 16, 2019}}</ref>
* OS-9000/SH4 can be found in loader (inside KIWI-format container LOADING.KWI) on Map CD/DVD for old automotive GPS navigation systems made by [[Matsushita Electric Industrial|Matsushita]] for Japan domestical market.
