Prolog to the Future

By the early 1960s, work on different implementations of the computer utility vision had begun at various places. As we have seen in the previous pages, the Cambridge, Mass., area was particularly active, initially because of the influence of John McCarthy. Besides the Compatible Time-Sharing System (CTSS) of F.J. Corbato, initially on an IBM 709 (1961) and later on the IBM 7090 and 7094 (1963), some of the other first working prototypes were also at MIT, for example, the DEC PDP-1 system of J.B. Dennis. At the Bolt Beranek and Newman Company in Cambridge. a time-sharing system based on a DEC PDP-1 was developed by J. McCarthy, S. Boilen, E. Fredkin, and J.C.R. Licklider. Other early influential prototypes were the Dartmouth College BASIC system of J. Kemeny and T. Kurtz, initially implemented on a GE 234: the JOSS system implemented at the Rand Corp. by C. Shaw: and. at the System Development Corp., a time-sharing system developed by J. Schwartz for the AN/FSQ-32 military computer. These developments were tracked for a short period by Lewis Clapp, then president of Computer Research Corp. of Belmont, Mass., in the "Time-Sharing System Scorecards. The last of these, published in fall 1967 (reproduced here, in modified form, with Clapp's permission), clearly shows the proliferation of systems that had occurred in the few years since Corbato demonstrated the first version of CTSS.

Time-Sharing System Scorecard This guide is prepared periodically to keep the reader abreast of the rapidly increasing number of time-shared computer systems which are bringing man and machine together in close partnership for the pursuit of intellectual and administrative activities. By glancing at the following charts the reader can judge for himself the progress which is being made in this new and dynamic field. There are several different definitions of time-sharing. No single definition is adequate for all purposes. We have limited this survey to systems which have at least two independent, remote and simultaneously operable consoles (from the user's point of view). If the language capabilities of the system are extensive and general so that a user can create new languages while working on-line, we have denoted this as a general-purpose time-sharing system. Where the language capabilities are more restrictive, permitting the user to work in only one specific problem area, we have used the term special- purpose time- sharing system.

The number of commercial and research time-sharing systems has grown so rapidly in the past several months that it is no longer possible to list each individual system in a brochure of this size. Therefore, we have listed only the first or major occurrences of any time-sharing system as has been supplied by the organization involved....
