Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family [1] manufactured beginning in 1966 [2] and discontinued in 1983. [3] [4] [5] 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. [a]
Model As used the original PDP-10 memory bus, with external memory modules. The later Model B processors used in the DECSYSTEM-20 used internal memory, mounted in the same cabinet as the CPU. The Model As also had different packaging; they came in the original tall PDP-10 cabinets, rather than the short ones used later on for the DECSYSTEM-20.
The PDP-6 Monitor software was first released in 1964. Support for the PDP-10's KA10 processor was added to the Monitor in release 2.18 in 1967. The TOPS-10 name was first used in 1970 for release 5.01. Release 6.01 (May 1974) was the first TOPS-10 to implement virtual memory (demand paging), enabling programs larger than physical memory to be ...
The PDP-10 was widely used in university settings, and thus was the basis of many advances in computing and operating system design during the 1970s. DEC later re-branded all of the models in the 36-bit series as the "DECsystem-10", and PDP-10s are generally referred to by the model of their CPU, starting with the "KA10", soon upgraded to the ...
PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
TOPS-20 was based upon the TENEX operating system, which had been created by Bolt Beranek and Newman for Digital's PDP-10 computer. After Digital started development of the KI-10 version of the PDP-10, an issue arose: by this point TENEX was the most popular customer-written PDP-10 operating systems, but it would not run on the new, faster KI-10s.
The College Football Playoff got underway Friday but the main course is spread out through Saturday. Three first-round games will be played across three separate campus sites from State College ...
The DEC KS10 PDP-10 model. [17] The UCSD Pascal P-machine processor designed at NCR by Joel McCormack. A number of MAI Basic Four machines. [18] The Tektronix 4052 graphics system computer. The SM-1420, Soviet clone of PDP-11, used Soviet clone of Am2901 (4 ICs in the CPU and 16 ICs in the FPU) [19] perhaps also used in others. [20]
