And Phil's text from https://www.ka9q.net/code/ka9qnos/ for archival purposes ( since the code it links to vanished, the page itself could vanish ):

My KA9Q NOS TCP/IP package began life way back in late 1985 on a surplus Xerox 820 computer board running CP/M with a 4 MHz Zilog Z-80 CPU, 64KB of RAM and a 8" floppy drive holding all of 243KB. ("KB" stands for kilo bytes -- not mega or giga). Shortly after that, it moved to the IBM PC with the 8088 and 80286 CPUs running MS-DOS.
KA9Q NOS was only the second known implementation of the Internet protocols for low-end computers; the first was MIT's PC/IP, which became the basis of the now-defunct company FTP Software, Inc. Unlike PC/IP, KA9Q NOS could simultaneously act as an Internet client, a server and an IP packet router, and it could handle multiple client and server sessions at once.
KA9Q NOS attracted many contributors and became very widely used throughout the late 1980s and early 1990s in amateur packet radio and in various educational projects. In a way, it was the Linux of its day, although Linux is now a far larger and more ambitious project. KA9Q NOS became the basis for several low-end commercial dialup terminal servers and routers. It also influenced the development of the Internet protocols and certain implementations, including the Linux kernel. It was also incorporated in the imbedded software in Qualcomm CDMA cellular phones. When I originally conceived NOS, affordable personal computers lacked the hardware support (especially memory management and a "protected" mode) needed to run a "real" operating system such as UNIX. The so-called "operating systems" then available for personal computers (e.g., MS-DOS and Windows 3.1) lacked any native support for the Internet protocols, so this package filled a real need. But that was a different era. KA9Q NOS is now largely obsolete, and I have not maintained it since the mid 1990s when Linux took off. If you are looking simply to connect your PC to the Internet, I recommend just using the native Internet support in your operating system of choice. If you need direct support for amateur (ham) packet radio, then Linux is your best bet. Much of the packet radio code from NOS, including the AX.25 implementation, is now a standard part of the Linux kernel. If you want to access packet radio from Windows, the most straightforward way is to set up a Linux system with AX.25 support and network the two with Ethernet. KA9Q NOS still has some utility in small imbedded applications. But you should also check out any of the several imbedded versions of Linux, such as Hard Hat Linux. For the diehards, and for historical interest, I'm still keeping my package here on the web. Two versions of my KA9Q NOS TCP/IP package available: The traditional real-mode version for Borland C++ 3.1: source zip archive DOS executable, as a ZIP archive. A 32-bit protected-mode version for DJGPP version 2. source zip archive. Other flavors of my code contributed by other volunteers along with other Internet-on-ham-radio packages are available at UCSD's FTP site. I am often asked questions about TCP/IP and amateur packet radio that entire books have been written to answer. So for those with a real interest in how TCP/IP works "under the hood", here is a list of books I can recommend. All but the last were written for the Internet as a whole and do not specifically cover amateur packet radio. Comer, Douglas E., Internetworking with TCP/IP, ISBN 0-13-468505-9 (2nd ed, 1991. First volume of a three-volume set). This first volume, subtitled Principles, Protocols and Architecture is probably the classic text for the theory behind the core Internet protocols. Lynch, Daniel C. and Rose, Marshall T., eds., Internet System Handbook, ISBN 0-201-56741-5 (1993, Addison-Wesley). A excellent collection of chapters on the various elements of the Internet's design by many of those who conceived them. Stevens, W. Richard, TCP/IP Illustrated, ISBN 0-201-63346-9, (1994, first volume of a two-volume set). This book emphasizes the practical aspects of the Internet protocols, such as performance and scaling issues, with many operational examples. An excellent companion to the Comer book. Wade, Ian, G3NRW, NOSintro: TCP/IP Over Packet Radio; An introduction to the KA9Q Network Operating System, ISBN 1-897649-00-2 (1992, Dowermain). This is the only book written specifically about TCP/IP in the amateur radio environment, and as the title implies it is primarily about using the KA9Q NOS in that environment. It's basically the exhaustive user's guide I never got around to writing myself. Last updated: 15 Mar 2002 |
