RT-11 (Real-time 11) is a discontinued small, low-end, [2] single-user real-time operating system for the full line of Digital Equipment Corporation PDP-11 16-bit computers. RT-11 was first implemented in 1970. It was widely used for real-time computing systems, process control, and data acquisition across all PDP-11s. It was also used for low ...
The PDP-14 was designed to process Boolean equations, usually expressed as “ladder diagrams” and as such had a programmable read-only program memory. Programs were developed using a PDP-8 then tested using a direct connection to the PDP-14. The PDP-14 was put into a check out mode where instructions were provided by the PDP-8.
It is the successor to PAL-11 (Program Assembler Loader), an earlier version of the PDP-11 assembly language without macro facilities. MACRO-11 is supported on all DEC PDP-11 operating systems. PDP-11 Unix systems also include an assembler (called "as"), structurally similar to MACRO-11, but with different syntax and fewer features.
The J-11 is a microprocessor chip set that implements the PDP-11 instruction set architecture (ISA) jointly developed by Digital Equipment Corporation and Intersil. It was a high-end chip set designed to integrate the performance and features of the PDP-11/70 onto a handful of chips. It was used in the PDP-11/73, PDP-11/83 and Professional 380.
The 11/34 supports up to 256 kB of Unibus memory. The PDP–11/34a (1978) [15] supports a fast floating-point option, and the 11/34c (same year) supported a cache memory option. PDP–11/60 – 1977. [15] A PDP–11 with user-writable microcontrol store; this was designed by another team led by Jim O'Loughlin. PDP–11/44 – 1979. [15]
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.

The PDP-7 was introduced in December 1964, and about 120 were eventually produced. [25] An upgrade to the Flip Chip led to the R series, which in turn led to the PDP-7A in 1965. [26] The PDP-7 is most famous as the machine for which the Unix operating system was originally written. [27] Unix ran only on DEC systems until the Interdata 8/32. [28]
