What is OS-9?

OS-9 is a real-time, multiuser, multitasking operating system
developed by Microware Systems Corporation.
It provides synchronization and mutual exclusion primitives in the
form of events, which are similar to semaphores. It also allows communication
between processes in the form of named and unnamed pipes, as well as shared
memory in the form of data modules.

OS-9 is modular, allowing new devices to be added to the system simply by
writing new device drivers, or if a similar device already exists, by simply
creating a new device descriptor. All I/O devices can be treated as files,
which unifies the I/O system. In addition, the kernel and all user programs
are ROMable. Thus, OS-9 can run on any 680x0 based hardware platform from
simple diskless embedded control systems to large multiuser minicomputers.

Originally developed for the 6809 microprocessor, OS-9 was a joint effort
between Microware and Motorola. The original version of OS-9 (OS-9 Level I)
was capable of addressing 64 kilobytes of memory. OS-9 Level II took
advantage of dynamic address translation hardware, and allowed a mapped
address space of one megabyte on most systems, and up to two megabytes on
others, most notably the Tandy Color Computer 3.

In the 1980's, Microware ported OS-9 to the 68000 family of microprocessors,
creating OS-9/68000, which is used in a variety of industrial and commercial
arenas, including Philips' CD-i. Code is mostly portable from OS-9/6809 to
OS-9/68000 at the high-level language source code level. Code is compatible
within either OS-9/6809 or OS-9/68000 at the binary level.

Where can I get OS-9?

Generally, a hardware vendor of a particular computer system will ship a
version of OS-9 for their platform. In addition, several
software vendors sell customized and enhanced OS-9 packages, and
Microware sells single license copies for
certain systems.

What machines run OS-9?

OS-9/68000 runs on a multitude of machines, including a variety of systems
from Hazelwood (such as the UniQuad I and II), the GMX
EISA, the Atari
ST, Commodore Amiga, Apple Macintosh, BlackHawk
Enterprises' (formerly IMS) MM/1,
FHL TC-70, and a large number of
680x0-based VME systems, manufactured by such companies as Radstone
Technology, Motorola, Heurikon, Inducom,
Force,
Mizar, ELSOFT, PEP Modular Computers, and others.
Gespac also makes a large number of platforms based
on their G-64 and G-96 bus.

OS-9/6809 runs on a variety of platforms, perhaps the most (in)famous being
the Tandy Color Computer. Other systems include the SWTPC SCB-69, the
Gimix 6809, Smoke Signal Broadcasting's Chieftain 6809, FHL's TC-9, the
Febe, and a host of others, most of which are SS-50 bus machines. Note
that OS-9/6809 is no longer supported by Microware, but many user groups,
BBSes, and a handful of FTP sites offer help and maintain software
collections for OS-9/6809.

What is DAVID?

DAVID is a configuration of OS-9/OS-9000 targeted towards the Interactive TV
Set Top Box (STB) market. DAVID stands for Digital Audio Video Interactive
Decoder. The unique characteristics of DAVID are that it will always include
the following IO subsystems:

SPF - Serial Protocol File Manager. Manages high speed, packet based, streaming
networks. Uses protocol modules to add support for X.25, UDP/IP, Q.2931, etc.

MPFM - Motion Picture File Manager. Manages the decompression and display of
MPEG encoded audio and video.

MAUI - Multimedia Application User Interface. Manages graphics overlay devices.
MAUI replaces the RAVE product used in previous systems, do to problems with
speed and real time responsiveness.

SCF - Sequential Character File Manager. Handles infra red remote controls or
tethered joysticks, gamepads, etc.

Like all OS-9 systems, DAVID may be expanded with any other file managers, but
these are considered the base case set.

DAVID has been shipping for the Motorola 68xxx family for over one year
(currently v1.1). This summer it will be updated to v2.0 and shipped for
68xxx, Power PC and 80x86 processor families.

Where do I get OS-9/68000 for the Macintosh?

Ultrascience (A division of Gibbs Laboratories)
makes a version of OS-9/68000 for the Macintosh. According to their
literature, it even allows the Macintosh operating system to run as a
process under OS-9.

Where do I get OS-9/68000 for the Commodore Amiga?

Digby Tarvin from Australia, has a port of
OS-9/68000 for the Amiga, which costs approximately $600 US.

Where do I get OS-9/68000 for the Atari ST?

Dr. Keil offers a port of OS-9 to the ST. Cumana,
however, recently stopped the business with OS-9 for the Atari because they
did not sell enough packages. Cumana OS-9 therefore is no longer supported
or sold.

What is OS-9000?

OS-9000 is a portable version of OS-9, written primarily in C. It can
potentially run on any 680x0 family member, and any 80386 or higher.
Code is portable across OS-9000 platforms at the source level.
Theoretically, OS-9000 can be ported to any modern computer architecture.
Currently the 80386/486 and Pentium are supported, with a port to the
PowerPC in development.

What software is available for OS-9?

Nearly any user application can be found either commercially or in the
public domain/shareware/freeware. Many word-processor, spreadsheets,
databases, and time management software packages are available from a
variety of vendors. A list of much of the available commercial software
is available from Microware. They publish the
"OS-9 Sourcebook", a listing of hardware and software vendors who sell
both 6809 and 68000 software and hardware. It is advisable to contact the
individual companies listed in the Sourcebook and request a recent catalog,
as the information in the Sourcebook is a tad outdated. Microware's
quarterly magazine Pipelines also carries new product announcements.

Where can I get public-domain/shareware/freeware software for OS-9?

There are many private bulletin boards around. Hopefully, someone will be
publishing a list of all known BBSes which have OS-9 software. The OS-9
International Magazine publishes a list of BBSes and FTP sites in each issue,
subject to update from its readership. In addition, there is the Princeton
Listserver, which acts as a mailing server that will mail requested software.
To begin using the Listserver, send electronic mail to
[email-masked], with the word HELP
in your message. Also, both the OS-9 Users Group, Inc. and
EFFO
maintain a library of public domain software, as well as distributes a
newsletter. Finally, there are a few anonymous FTP servers worldwide with
OS-9 software on them.

chestnut.cs.wisc.edu

wuarchive.wustl.edu

lucy.ifi.unibas.ch

Don't forget the often overlooked mailserver on chestnut. The e-mail address
is [email-masked], and a message with "help" as the body will
return some help text. This provides a way for those without FTP
access to snarf stuff from chestnut via mail.

Chestnut contains mostly OS-9/68000 software, including the complete
TOP package, many EFFO disks, GCC
and G++, (and many other GNU
products such as flex and bison), ka9q, k5jb, TeX, LaTeX, and quite a
bit of 6809 software.

Wuarchive has mostly 6809 OS-9 software; Lucy is meant to be a European
duplicate of chestnut.

Where can I get online information about OS-9?

There are several newsgroups and mailing lists on the internet which
discuss OS-9 and its derivatives. On Usenet NetNews, the following
groups cover OS-9, the first of which more so than the others:

comp.os.os9

comp.sys.m68k

comp.sys.m6809

comp.realtime

CompuServe and Delphi both have OS-9 forums with a files section for
downloads of some of the latest OS-9/68000 and OS-9/6809 shareware.
On-line conferences are regularly scheduled on Delphi's OS-9 forum on a
variety of topics.
GEnie also has OS-9 support with OSK files found in a section of
the Atari ST RoundTable and CoCo OS-9 and MM/1 files found in the Tandy
RoundTable.

Also, the Princeton Listserver carries a discussion forum for the
Tandy Color Computer and its derivatives, which often includes
discussion of OS-9/6809. To get information about the
listserver, send e-mail to [email-masked], with the word
HELP as the body of the message. The listserver also maintains a
file collection of CoCo software.

Finally, [email-masked] is a mailing
list of OS-9 related discussions. To subscribe to this list, simply
send mail to:

[email-masked]

with the email body

"subscribe fatcat "

Public Messages should be sent to:

[email-masked]

Messages sent to this account are "re-broadcast" to the list.

What is the OS-9 Users Group?

The OS-9 Users Group, Inc. is a non-profit organization based in
the United States. In addition to maintaining a library of OS-9 software,
it distributes the MOTD newsletter to its members and is currently
working on various methods of supporting personal and industrial OS-9
users. Click
here for the OS-9 Users Group FAQ, where more detailed information is
available.

What is the TOP package?

TOP is an acronym for "The OS-9 Project". It is a collection of
OS-9/68000 software developed primarily in Germany and available through
ftp on chestnut.cs.wisc.edu. Much of it seems to
be an attempt to make OS-9 a little more UNIX-like. Many standard UNIX
utilities are provided, as well as a complete UUCP mail implementation,
and a more secure password file and login program. Many traditional
UNIX games are also provided. The total package consumes approximately
16 MB of disk space, though much of this is source code.

What is the EFFO?

EFFO, The European Forum For OS-9 maintains a large library of
PD Software for OS-9,e.g. the new C-Kermit 5A, an improved KA9Q
Software called SLIP for OSK, Ghostscript and many other fine
products. The software is available at a nominal handling fee,
including a written instruction or even a complete users manual.

Are there any independent magazines covering OS-9?

Currently there are two magazines which cover OS-9 topics:
International OS-9 Underground Magazine and
OS-9 International as the official publication of
EFFO. Both magazines are written in English.

What books are available that cover OS-9 topics?

Here is a listing of currently available books.

Are there alternative shells for OS-9?

Yes, there are. Microware sells MShell, an enhanced shell. In
addition, there are several public domain shells available. The most
notable of which is the Bourne shell, sh, available in the TOP package
(OS-9/68000) in its original version. A newer version with may enhancements
and bug fixes is available through EFFO. sh supports aliasing, command-line editing, history,
environment variable replacement, shell scripting, the `command`
operator (which uses the output of the command as arguments to the
called program), and a startup file.

For users feeling at home in a VAX/VMS surrounding, the zsh shell is
commercially available from ELSOFT.

A PD version of ksh is available on chestnut. Bash, the GNU
shell, has also recently been ported. Bash is available on chestnut.cs.wisc.edu

For OS-9/6809, there is Shell+ and if you have a
Color Computer 3, there is always GShell a graphical shell.

Can one read/write MS-DOS format disks under OS-9?

Yes, there are several public-domain and commercially avaliable
utilities to accomplish this task, for both OS-9/6809 and OSK. One of
the more interesting is the MSFM file manager which appears in
OS-9 Insights, a book by Peter Dibble, available through Microware.
MSFM is an actual file manager, which allows you to mount an MS-DOS
floppy as part of the OS-9 file system.

What communications software is available?

Many public domain utilities, available from your local BBS,
include terminal emulators and file transfer utilities (such as
xmodem, ymodem, zmodem, and kermit protocols.) Sterm, a non-commercial
package, also supports Compuserve B+ protocol. In addition, many
software vendors sell various equivalent packages. C-kermit is
available in source and executable form for OS-9/68000 on chestnut.cs.wisc.edu.

Also, Microware sells the NFM Network File Manager, which is a
local-area networking protocol for small networks of strictly OS-9
based computers. NFM runs on virtually any network interface,
including direct serial links, ARCnet, Ethernet, and others.

Microware also sells the ISP, or Internet Support Package, which is a
relatively complete TCP/IP package, including telnet client and server
applications, and FTP client and server. It also provides a C BSD 4.2
compatible socket library. Closely related is the ESP, or Ethernet
Support Package. This is similar to ISP, but is for particular
Ethernet boards. Current word from Microware says that the ESP is now
obsolete, and has been replaced by a preconfigured version of the ISP.
ISP supports Ethernet and SLIP.

Microware also sells NFS, or Network File System, for OS-9/68000. This
allows an OS-9 system to share files in a heterogeneous environment
(i.e. not all the machines on the network run OS-9.) NFS requires ISP
or ESP.

There is a port of the Phil Karn ka9q internet software
package, which supports a single-user interface to TCP/IP. It includes
a telnet client, an FTP client and server, and SMTP. Source and
executables may be found on chestnut. Note that the executables on
chestnut have a bug in the FTP server which causes it to bus trap
occasionally. The newer k5jb code should correct this. (The author of
this FAQ has not had a chance to test the newer software yet.)

EKF Elektronik sells, in addition to the Microware
networking software, two additional networking protocols:

DECnet

Novell/IPX

For more information on these products, you can contact Gerald
Nimmrich at EKF ([email-masked]).

PEP Modular Computers provides the following network protocols:

DECNET

Novell/IPX

SINEC H1

ProfiBus

CANBUS

BitBus.

What about usenet and news?

Several ports of UUCP software are available for both OS-9/6809 and
OS-9/68K. A port of C news and RN are available on chestnut.cs.wisc.edu. TOP has
ported Notes, which maintains Notesfiles. There is a program which
will transfer between Notesfiles and netnews. The TOP package in its
entirety may be found on chestnut.

Rick Adams' UUCP port for OS-9/6809 is also available, and this
has been updated to UUCPbb by Bob Billson and others. UUCPbb is also
available for OS-9/68000 and may be found on wuarchive and chestnut,
as well as on Delphi and CompuServe. A nice companion mail reader for
this package called Palm, which has Elm-like features, is also
available. UUCPbb features:

UUCPbb features:

a fairly complete implementation of UUCP

mail and news processing with reader programs

UUCP management utilities

full C source code

Click here to ftp UUCPbb and Palm.

Elm has also been ported to OSK, and is available on chestnut.
The Elm package is a port of elm 2.4; it fits in the rmail/lmail/uucp
environment that can be found in the TOP package.

Elm features:

e-mail address data base with aliases

very friendly user interface

anwering machine, etc.

For more information on Elm, contact Harold Groene.

Is GCC available for OS-9?

GCC and g++ are available for OS-9/68000, both in OS-9 executable form and
cross-compiler form. Version 1.37 was ported to OS-9 by Atsushi Seyama and was
then supported and updated to the version 1.39, 1.40, and 1.42.2 by
Stephan Paschedag. Source and binaries are available on chestnut.cs.wisc.edu
via anonymous FTP. The 1.40 versions and up support 68040 optimizations.
Version 2.x of GCC is a completely new port to OS-9 which allows better
optimization. The first version that was released was version 2.4.5 which
is available on chestnut.cs.wisc.edu in /pub/OSK/GCC/BIN/gcc_2.4.5_cmds.lzh.
The current edition (V2.5.8) includes a new I/O library which gives full
compatibility with C++ programs (I/O streams). It also supports the different
calling interfaces of Microware's compilers (cc V3.x and UltraC).
Version 2.6.x of GCC and G++ is expected for the end of 1994.

Bear in mind that the newer editions (2.x) will require at least 4 MB of
memory free in order to run.

Can I run X11 on OS-9?

Yes. Microware sells a port of X11R5 (client and server plus
optional Motif). Eltec Electronik GmbH sells an X11R4 port.

Kei Thomsen has also done a port of X11R5 and X11R6. His port requires
Microware sockets, GCC 2.x, OS9lib.l (unix compatibility routines),
and a bourne shell for running imake. It requires a minimum of 4 MB
physical memory, 8MB if you plan to run any applications. To quote
Kei:

"I have ported two X11R5 server: One with the standard CFB (Color
Frame Buffer) support, and one (very fast) for my VGA ET4000. Both are
running very stable. The Server is about 650 KB and use 300 - 2000 KB
additional memory, or 1 MB for the PEX server. "

What other graphics alternatives are there?

Several other organizations have various graphics packages for OS-9.
Reccoware Systems has a port of the Bellcore MGR window manager.
Gespac produces G-Windows, a portable windowing package which has
device windows and a very Motif-looking interface. For the MM/1,
BlackHawk Enterprises sells KWindows, a window manager
similar to the Multi-Vue OS-9 window package for the Tandy Color
Computer 3. Microware also sells RAVE, the Real-Time Audio Video
Environment.

What is a Real Time system?

A real-time system is any system whose correctness depends not only
on the correctness of the applied algorithms, but also in the timing of
the execution of those algorithms. Refer to the netnews comp.realtime
newsgroup for more information.

Does OS-9 support multiple threads within a program?

No, not directly like Mach does, but through the use of user
installed periodic interrupts or alarms, a user program can support it's
own threads. Consult a good operating systems book for more details.
