By Susan J. Shepard from the July 1987 issue of Computer Language The Intel 80386 microprocessor is here—at last. It is proving to be all that we expected, and the last obstacle to 386 supermicrocomputers is an operating system that can avail the developer and user of its power. It will provide a powerful and affordable platform for expert systems and other AI applications that are truly useful. AI has been been waiting for this chip; many AI applications developers whispering, “When the 386 is available…” and hinting of powerful systems for the desktop and a rich development environment for the programmer working and learning in the real world.

by Marshall Kirk McKusick from the January 1985 issue of Unix Review magazine Ken Thompson and Dennis Ritchie presented the first UNIX paper at the Symposium on Operating Systems Principles at Purdue University in November, 1973. Professor Bob Fabry was in attendance and immediately became interested in obtaining a copy of the system to experiment with at Berkeley. At the time, Berkeley had only large mainframe computer systems doing batch processing, so the first order of business was to get a PDP-11/45 suitable for running the then current Version 4 of UNIX.

A Good Buy on UNIX Special Report by Dean Hannotte from the June 12, 1984 issue of PC Magazine The Mark Williams Company’s COHERENT operating system is a rewritten version of the seventh edition of UNIX, with some extensions and enhancements. Regrettably, it has incoherencies. The Mark Williams Company’s COHERENT operating system is a State-of-the-art microcomputer implementation of AT&T’s UNIX, without the state-of-the-art AT&T licensing fees. It is a completely rewritten version of the seventh edition of UNIX and includes some of its multi-user and multitasking abilities.

by Stephen L. Childress from the July 1983 issue of Micro magazine (Note: The figures are not available for this article because they are impossible to read on my source.) The modularization of the I/O system allows OS-9 to enhance the standard I/O at run time, not assembly or patch time. Device names and addresses are not fixed by the operating system but, rather, the program may attempt I/O to any device name.

by Stephen L. Childress from the June 1983 issue of Micro magazine Unless you’ve been on sabbatical to Siberia of late you will have noticed the swell of interest in the Unix operating system software. Most new and all the old popular 16-bit computers are supporting Unix or one of the numerous look-alikes. Why all the furor? It seems at last we’ve begun to rethink computer programming and usage. Recognizing that software development is expensive and timeconsuming, we must exploit the falling cost of today’s hardware.

By Stephen J . Shaw from the November 1983 issue of Mini-Micro Systems magazine Slowly but earnestly, companies in the artificial intelligence (AI) field are bringing out the tools to build the heralded Fifth Generation computer systems. It’s likely to take several years for any AI-based products to have a major impact in the commercial market. But 1983 could be the year AI emerges from its R&D cocoon. Many significant product developments are coming from recently formed companies devoted exclusively to AI.

by Stephen Beale from the November 1997 issue of MacWorld magazine Apple Computer drove spike through the heart of its Mac OS-Iicensing program when it announced on September 2 that it will acquire the core assets of Power Computing, the company that built the largest Mac-clone business. Apple will exchange $ 100 million in common stock for Power Computing’s Mac OS license and 200,000-name mailing list, and also has the right to retain Power Computing executives involved in direct marketing, distribution, and engineering.

by Phil Daley from the June 1983 issue of Micro magazine The operating systems that I have seen available for the Apple use essentially the same read/write routines, but they have been modified or changed. All the disks created by any one system can be read by any other system if you know the procedure. Modifying disks to make them copyprotected (unreadable) is a different technique and a different topic. The Operating Systems covered in this article all use standard DOS 3.

by Steven Noble from the February 1997 issue of Australian MacUser magazine Apple computer has bought NeXT Software, and is going to use that company’s high-perfor­mance operating system (OS) NeXTstep as the basis of the next major revision of the Mac OS - code-named Rhapsody. This is good news, because NeXTstep has many of the fea­tures that bring speed, stability and strength to next-generation operating systems, including protected memory, preemptive multitasking, and a modern vir­tual memory system.

from the June 1, 1987 issue of MacWEEK by John Markoff Apple Computer Inc.’s next generation of computers may be based on a radically new microprocessor architecture that could improve performance dramatically over today’s Macintosh designs. Such computers would be built around microprocessors combining elements of both Reduced Instruction Set Computer (RISC) and multiprocessor design onto a single silicon chip. Apple’s advanced development team is now at work using its Cray XMP supercomputer to simulate the design of the new chips.
