    Software Product Description DIGITAL CLASSIFIED SOFTWARE PRODUCT NAME: SUSPENDEDn.\ Version 8.0 SPD A2.90.01 DIGITAL distributes this software product under license from lnfocom, Incorporated. DESCRIPTION: SUSPENDEDT" is a Prose Entertainment Package developed using an Artificial lntelli­ gience Language called INTERLOGIC™. INTERLOGIC allows the creation of the enter­ tainment software in such a way that the user carries on a free format, textural conversa­ tion with the software. The user is able to interact with the program using omplete sentences rather than two-word commands with greater vocabulary and more command options. SUSPENDED places the user in a situation of awakening from a frozen state of suspension on a planet in a future time. The planet is in total chaos which threatens to destroy life support systems. The user must bring conditions under control by acting through a robot crew, each of whom offers a distinctly differect view of the world. The user's success if dealing with this catastrophe will determine his fate. No hints, clues or any additional information on the progress of this game will be provided by DIGITAL.

  • Kermit User Guide
    KERMIT USER GUIDE Seventh Edition Christine Gianone, Editor Columbia University Center for Computing Activities New York, New York 10027 May 26, 1988 Copyright (C) 1981,1988 Trustees of Columbia University in the City of New York Permission is granted to any individual or institution to use, copy, or redistribute this document so long as it is not sold for profit, and provided this copyright notice is retained. PREFACE Page 1 PREFACE Kermit is the name of a protocol for transferring files from one computer to another over ordinary asynchronous terminal connections. Kermit programs have been written for many different computers, and in general any two computers that have Kermit programs can exchange sequential files correctly and completely. This manual gives a brief and general overview of what Kermit is and how to use it, but consists mostly of detailed instructions for use and installation of specific Kermit programs. For a more detailed introduction to Kermit, complete with illustrations, diagrams, and tutorials, consult the book Kermit, A File Transfer Protocol, by Frank da Cruz, Digital Press, Bedford MA (1987), ISBN 0-932376-88-6, DEC order number EY-6705E-DP (phone 1-800-343-8321). The Kermit book describes Kermit in detail, from the points of view of the beginner, the user, the computer professional who must install Kermit programs or support their use, and the programmer who wishes to write new Kermit implementations. Also included are general introductions to computers, data communications, and file organization, plus a detailed troubleshooting guide, bootstrapping hints, and various appendices and tables. The latter half of the book is taken up by a complete description of the Kermit file transfer protocol, with programming examples in the C language, plus some analysis and comparisons of Kermit with other popular protocols such as Xmodem.

  • Kermit Distribution Manual
    Columbia University Center for Computing Activities KERMIT DISTRIBUTION MANUAL Chris Gianone, Frank da Cruz 25 April 1988 Kermit Distribution Manual Page 1 1. Overview This manual describes procedures that are always changing. If you have questions or comments, mark up your copy of this manual and give it to Chris or Frank, so we can make it clearer or more complete. Thanks! Kermit is a computer file transfer protocol developed at Columbia University, and a large collection of computer programs to implement this protocol, and to perform other data communication functions. This collection of software is kept at Columbia and distributed all over the world. Kermit has been distributed by Columbia since 1981. At first we asked for no money, just a tape and a return mailer. Starting in May 1983, we discontinued this practice and asked for a distribution fee of $100 for a tape containing all the available Kermit programs. In June 85, the collection could no longer fit on a single tape, so we had to make two tapes, A and B. By November 86, we needed a third, tape C. And in August 1987, we expanded to five tapes. Kermit Distribution is part of the Systems Group at the Columbia University Center for Computing Activities (CUCCA). It consists of an Administrator (Christine Gianone), a full time production coordinator (formerly Bob Tschudi, position currently vacant), and a staff of part time students. Chris is the manager of Kermit Distribution, with responsibility for hiring and supervision of the production coordinator and part-timers, design of distribution procedures, arbitration of conflicts among the staff, or between the staff and customers, and all related issues.

It does this through a historical case study of Digital Equipment Corporation, an innovator and market leader of minicomputers who faltered and eventually failed during the period of technological change brought on by the emergence of the personal computer. The failure of Digital Equipment Corporation is interesting because it occurred despite its ability to adapt to changing technological forces.

The bulk of the collection was collected and created during the company’s years of operation from 1957 to 1998. DEC, founded by engineers Ken Olsen and Harlan Anderson, was one of the largest and most successful computer companies in the industry’s history. Widely recognized for its PDP and VAX minicomputer product lines, by 1988 DEC was second only to IBM as the world’s largest computer company. This collection holds the papers of DEC’s executives, engineers, and personnel -- including the personal collections of founders Ken Olsen and Harlan Anderson. Also included are DEC’s administrative records and material relating to product development and engineering, with committee meeting minutes, correspondence, internal newsletters, product proposals, and engineering drawings.
