• Pdp-10

  computer 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 […]

• 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 […]

• Pdp-6

  computer 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 (1996-12-21)

• Pdp-7

  computer 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 […]
