PDP-10 systems on the ARPANET highlighted in yellow. 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.
DECSYSTEM-2020 front panel 2 DECSYSTEM-2020 KS-10s (1979) at the Living Computer Museum. The DECSYSTEM-20 was a family of 36-bit Digital Equipment Corporation PDP-10 mainframe computers running the TOPS-20 operating system and was introduced in 1977.
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 ...
The local spelling "TURIST" is an artifact of six-character filename (and other identifier) limitations, which is traceable to six SIXBIT encoded characters fitting into a single 36-bit PDP-10 word. "TURIST" may also have been a pun on Alan Turing , a pioneer of theoretical computer science . [ 11 ]
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 ...
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.
Foonly Inc. was an American computer company formed by Dave Poole [2] in 1976, [4] that produced a series of DEC PDP-10 compatible mainframe computers. [5]The first and most famous Foonly machine, the F1, was the computer used by Triple-I to create some of the computer-generated imagery in the 1982 film Tron.
Smaller machines like the PDP-1/PDP-9/PDP-15 used 18-bit words, so a double word was 36 bits. These computers had addresses 12 to 18 bits in length. The addresses referred to 36-bit words, so the computers were limited to addressing between 4,096 and 262,144 words (24,576 to 1,572,864 six-bit characters).
