pdp-10 (foldoc) | PDP-10
 
     Programmed Data Processor model 10.
 
    The series of mainframes from DEC that made time-sharing
    real.  It looms large in hacker folklore because of its
    adoption in the mid-1970s by many university computing
    facilities and research labs, including the MIT AI Lab,
    Stanford, and CMU.  Some aspects of the instruction set
    (most notably the bit-field instructions) are still considered
    unsurpassed.
 
    The PDP-10 was eventually eclipsed by the VAX machines
    (descendants of the PDP-11) when DEC recognised that the
    PDP-10 and VAX product lines were competing with each other
    and decided to concentrate its software development effort on
    the more profitable VAX.  The machine was finally dropped from
    DEC's line in 1983, following the failure of the Jupiter
    Project at DEC to build a viable new model.  (Some attempts by
    other companies to market clones came to nothing; see Foonly
    and Mars.)  This event spelled the doom of ITS and the
    technical cultures that had spawned the original {Jargon
    File}, but by mid-1991 it had become something of a badge of
    honourable old-timerhood among hackers to have cut one's teeth
    on a PDP-10.

pdp-11 (foldoc) | PDP-11
 
    Programmed Data Processor model 11.
 
    A series of minicomputers based on an instruction set
    designed by C. Gordon Bell at DEC in the early 1970s (late
    60s?).  The PDP-11 family, which came after, but was not
    derived from, the PDP-10, was the most successful computer
    of its time until it was itself succeeded by the VAX.
 
    Models included the 11/23 and 11/24 (based on the F11
    chipset); 11/44, 11/04, 11/34, 11/05, 11/10, 11/15, 11/20,
    11/35, 11/40, 11/45, 11/70, 11/60 (MSI and SSI); LSI-11/2
    and LSI-11 (LSI-11 chipset).  In addition there were the 11/8x
    (J11 chipset) and SBC-11/21 (T11 chip) and then there was
    compatibility mode in the early VAX processors.
 
    The B and C languages were both used initially to
    implement Unix on the PDP-11.  The microprocessor design
    tradition owes a heavy debt to the PDP-11 instruction set.

pdp-20 (foldoc) | PDP-20
 
    The most famous computer that never was.  PDP-10 computers
    running the TOPS-10 operating system were labelled
    "DECsystem-10" as a way of differentiating them from the
    PDP-11.  Later on, those systems running TOPS-20 were
    labelled "DECSYSTEM-20" (the block capitals being the result
    of a lawsuit brought against DEC by Singer, which once made a
    computer called "system-10"), but contrary to popular lore
    there was never a "PDP-20"; the only difference between a 10
    and a 20 was the operating system and the colour of the
    paint.  Most (but not all) machines sold to run TOPS-10 were
    painted "Basil Blue", whereas most TOPS-20 machines were
    painted "Chinese Red" (often mistakenly called orange).

pdp-6 (foldoc) | PDP-6
 
     Programmed Data Processor model 6.  A computer
    designed around 1960 with more or less exactly the same
    hardware architecture as the PDP-10.  It already had
    multi-user time sharing and batch processing and
    multi-level priority interrupts

pdp-7 (foldoc) | PDP-7
 
     A minicomputer sold by DEC in 1964.  It had a
    memory cycle time of 1.75 microseconds and add time of 4
    microseconds.  I/O included a keyboard, printer, paper-tape
    and dual transport DECtape drives (type 555).
 
    DEC provided an "advanced" Fortran II compiler, a Symbolic
    Assembler, Editor, DDT Debugging System, Maintenance
    routines and a library of arithmetic, utility and programming
    aids developed on the program-compatible PDP-4.
 
    [DEC sales brochure].
 
    The PDP-7 was considered reliable enough (when properly
    programmed) to be used for control of nuclear reactors and
    such.
 
    Around 1970 Ken Thompson built the operating system that
    became Unix on a scavenged PDP-7 so he could play a
    descendant of the SPACEWAR game.

pdp-11 (jargon) | PDP-11
 
 
     Possibly the single most successful minicomputer design in history, a
     favorite of hackers for many years, and the first major Unix machine, The
     first PDP-11s (the 11/15 and 11/20) shipped in 1970 from DEC; the last
     (11/93 and 11/94) in 1990. Along the way, the 11 gave birth to the VAX,
     strongly influenced the design of microprocessors such as the Motorola 6800
     and Intel 386, and left a permanent imprint on the C language (which has an
     odd preference for octal embedded in its syntax because of the way PDP-11
     machine instructions were formatted). There is a history site.
