L'estate Dei Grandi Accordi = NEWS L'estate dei grandi accordi Gli scenari futuri dell'informatica degli anni '90 di Paolo Ciardelli e Valter Di Dio C'è una tesi secondo la quale prima o poi i Palestinesi e gli Israeliani si metteranno d'accordo, per cui anche la Apple e la IBM non si faranno più la guerra. La prima è ancora lontana ma la seconda? Un articolo al riguardo apparso sul numero di luglio di MCmicrocomputer iniziava così: «Cosa stanno tramando le due più grosse compagnie di computer americane? /I 10 giugno John Sculley presidente della Apple Inc. si è recato, per un incontro preliminare con John Akers, negli uffici di New York della 18M.

At its heart was the 8-bit 8080 microprocessor chip from InteL The other board provided 256 bytes of memory. The Altair had no keyboard, no monitor, and no permanent storage. But it had a revolutionary price tag. It cost $397. For the first time, the term "personal computer" acquired a real-world meaning. The real world of the Altair was not, however, the world of business computing. It was-primarily the world of the computer hobbyist These first users of the microcomputer were not as interested in using spreadsheets and word processors as they were in programming. Accordingly, the first soft- ware for the Altair was a programming language.

  • “Not Only Microsoft: the Maturing of the Personal Computer Software
    Martin Campbell-Kelly Not Only Microsoft: The Maturing of the Personal Computer Software Industry, 1982-1995 In the thirteen years following the introduction of IBM's first personal computer in 1982, Microsoft rose from being a small concern to become the colossus of the PC software industry. However, Microsoft was not the only software company to profit from the PC-software boom: firms like AutoDesk, Lotus Development, WordPerfect Corp., Ashton-Tate, Novell, Borland, Adobe Systems, Aldus, Symantec, and the Santa Cruz Operation all had their time in the sun. Whereas some of these firms lost their markets to Microsoft or stumbled through strategic errors, others remained hugely successful, and their relative obscurity is largely due to the contemporary obsession with Microsoft and its billionaire founder. he early history of the personal computer is well known. It has fea- Ttured in the press, in numerous popular histories of computing, and in television programs such as Robert X. Cringley's "Triumph of the Nerds."1 Within the business history community, the story is known at a deeper level, partly through the inevitable osmosis that ac- companies the daily use of a personal computer, but also through arti- cles such as Richard Langlois's study of the microcomputer industry, MARTIN CAMPBELL-KELLY is a reader in computer science at the University of War- wick, England.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract For years, rumors have circulated that the code for the original DOS operating system created by Microsoft for the IBM personal computer is actually copied from the CP/M operating system de- veloped by Digital Research Incorporated. In this paper, scientifically tested and accepted forensic analysis mathematical techniques, step-by-step processes, and advanced software code compari- son tools are used to compare early versions of the two code bases. The conclusion is reached that no copying of code takes place1. Keywords DOS, CP/M, Copyright Infringement, Software Forensics, Software Correlation 1.

Paradigm Shift: The Graphical User Interface By 1982, the personal computer paradigm had reached technological “closure” with the IBM-compatible PC equipped with an Intel 8086 or 8088 microprocessor and the MS-DOS operating system. In the classic way in which technologies are shaped, however, no sooner had this technical closure been achieved than a new “critical problem” came into view.25 The most commonly perceived problem with the personal computer was the lack of “multitasking”—the ability for a user to work simultane- ously with two or more applications.

    Legacy of Gary Kildall: The CP/M IEEE Milestone Dedication Speakers: Robert Huitt Gordon Eubanks Tom Rolander David Laws Howard E. Michel Brian Halla John Wharton Brian Berg Weilian Su Scott Kildall Bill Kampe Recorded: April 25, 2014 Pacific Grove, California Edited by David Laws CHM Reference number: X7170.2014 © 2014 Computer History Museum Legacy of Gary Kildall: The CP/M IEEE Milestone Dedication EDITOR’S NOTE: Gary A. Kildall, an instructor in Computer Science at the Naval Postgraduate School in Monterey, CA and a software contractor to Intel Corporation, Santa Clara, CA demonstrated the first working prototype of CP/M (Control Program for Microcomputers) in Pacific Grove, CA in 1974. Together with his invention of the BIOS (Basic Input Output System), Kildall’s operating system allowed a microprocessor-based computer to communicate with a disk drive storage unit and provided an important foundation for the personal computer revolution. Kildall and his wife Dorothy McEwen founded Digital Research Inc. (DRI) in 1976 to commercialize the software. The following text is a transcription of a video recording of an event held at Pacific Grove City Hall on April 25, 2014 as part of the dedication of an Institute of Electrical and Electronic Engineers (IEEE) Milestone plaque to commemorate the “The CP/M Microcomputer Operating System, 1974.” Some extraneous comments that do not add to the content have been omitted.
