Retrospective: what have we learned from the PDP-11---what we have learned from VAX and Alpha

Gorden Bell, W. D. Strecker
1998 25 years of the international symposia on Computer architecture (selected papers) - ISCA '98  
Our paper "Computer Structures: What Have We Learned from the PDP-11" [l] was written at the time the VAX architecture was being developed, and the learning reported in that paper would strongly influence  ...  In this retrospective, we will review how the PDP-11 learning influenced VAX. Next we will discuss what we learned from the VAX architecture.  ...

A structured data base computer conferencing system

George W. Arnold, Stephen H. Unger
1977 Proceedings of the June 13-16, 1977, national computer conference on - AFIPS '77  
A key feature of CBIE is that the conference record is structured by the users in the form of a network of elements systematically related to one another.  ...  Each individual, at his own convenience, examines the existing conference records, via a terminal connected to the computer by a telephone line, and adds his own comments.  ...  Howard Eskin of the Columbia University Computer Center has been most helpful with advice and cooperation concerning the implementation.  ...

SP/k: a system for teaching computer programming

R. C. Holt, D. B. Wortman, D. T. Barnard, J. R. Cordy
1977 Communications of the ACM  
The features of the SP/k language were chosen to encourage structured problem solving by computers, to make the language easy to learn and use, to eliminate confusing and redundant constructs, and to make  ...  Each subset is precisely defined and can be learned or implemented without the following subsets.  ...  The compiler was implemented by the four authors, with assistance from B.L. Clark, F.J.B. Ham, M.S. Fox and W.K. Fysh. The special purpose PDP-11 operating system was implemented by I.E.  ...

Technological Competition and the Structure of the Computer Industry

Timothy F. Bresnahan, Shane Greenstein
2003 Journal of Industrial Economics  
Accordingly, once we have built our within-segment framework, we end this section by looking at market structure in segments with quite different demand and supply characteristics from those in IBM mainframes  ...  It played a central role in the concentrated structure of the mainframe segment from 1964 onwards, and in the persistence of IBM's dominant position.  ...  They included servicing, training, and a maintenance arrangement. 23 The hardware for a supermini such as the VAX-11/780 was not really much different from its technical ancestors (i.e., the PDP-11).  ...

University Education on Computers [chapter]

Reino Kurki-Suonio, Oddur Benediktsson, Janis Bubenko, Ingemar Dahlstrand, Christian Gram, John Impagliazzo
2009 IFIP Advances in Information and Communication Technology  
Following a session on university education, this panel discussed early Nordic visions and experiences on university computing education, contrasting them to today's needs and the international development  ...  This report gives short papers by the panelists (their opening statements), and a brief summary (the chair's interpretation) of the views that were raised in the ensuing discussion.  ...  In computer science, we are interested in making the machine do exactly what we want it to do, whereas in system design a major problem is to determine what we want the computer to do.  ...
