The PDP–11 is a series of 16-bit minicomputers originally sold by Digital Equipment Corporation (DEC) from 1970 into the late 1990s, one of a set of products in the Programmed Data Processor (PDP) series.

2023年7月31日 · The PDP-11 computer is one out of a series of 16-bit minicomputers manufactured and offered to the public by Digital Equipment Corporation (DEC) between 1970 and the early 1990s.

2022年3月14日 · The PDP-11 helped birth the UNIX operating system and the C programming language. It would also greatly influence the next generation of computer architectures.

The PDP-11 is a series of minicomputers introduced in 1969 [1] by the Digital Equipment Corporation (DEC), in production by them from 1970-1990.

hardware. This Handbook describes the PDP-11/40, one of the latest computers in the PDP-11 family from Digital Equipment Corporat. on (DEC). This powerful, low-priced machine is packaged in a 21·'' front panel slide chassis, allowing convenient access and …

The PDP-11/44 was a high performance UNIBUS PDP-11 system; in some senses a lower-cost successor to the PDP-11/70, although without the very high main memory bandwidth and I/O bandwidth to mass storage of the -11/70, as it lacked the latter's Main Memory Bus and integrated MASSBUS, relying instead on the UNIBUS, and EUB.

The PDP-11 architecture[1] is a 16-bit CISC instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). It is implemented by central processing units (CPUs) and microprocessors used in PDP-11 minicomputers.

The PDP-11 was an extremely successful and influential family of machines which has spanned over two decades from the early 1970s through the mid 1990s. The first PDP-11 in 1970 cost $10,800 and was DEC's first and only 16 bit computer.

The PDP-11 family has probably been the most successful minicomputer ever (though the PDP-8 was also immensely popular). The PDP-11 had a very concise and consistent architecture; almost RISC like. The DEC VAX computer line followed the PDP-11, but it's architecture was much more complicated. The PDP-11 also introduced the DEC UNIBUS® bus design.

This book describes PDP-11 systems and sections on hardware including the LSI-11/2, LSI-11/23, FALCON SBC-11/21, PDP-11/23-PLUS and the operating systems RT-11, RSX-11M, RSX-11M-PLUS, RSTS/E, RSX-11S, and SIMRT.
