Pdp 11

The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer The PDP-11 architecture is an instruction set architecture developed by Digital Equipment Corporation. It is implemented by central processing units and microprocessors used in PDP-11 minicomputers. It was in wide use during the 1970s, but was eventually overshadowed by the more powerful VAX-11 architecture in the 1980s

The PDP-11 (Programmed Data Processor) was one the (if not the) most successful computers of all times. It began its career as a minicomputer, and ended up as a micro or supermicro/supermini. It was manufactured from 1970 since the early 1990s F-16 simulation Viperpit cockpit constructio PDP-11 series of 16-bit minicomputers produced by Digital Equipment Corporation from 1970 to 1990, and by Mentec from 1994 onwards The PDP-11 does not seem to have overcome this weakness, although it appears that more complex systems are being built successfully with the PDP-11 than with its predecessors, the PDP-8 and PDP-15. Because of their minimal nature, mini computers were not pleasant environments on which to write programs I have a PDP-11/44, which runs 2.11BSD and also run RSX11M-PLUS. This is an old picture of the machine, as originally configured. The Cipher F-100 tape drive died, so now I have dual RX-02 floppy drives installed above the CPU, and a Kennedy 9600 Formatted Pertec auto-loading 9-track tape drive above the RX02's

RACAL based radio amateur statio The PiDP-11 is a modern replica of the PDP-11/70. Introduced in 1975, the 11/70 was top of the line in the famed PDP-11 range, and the very last system with a proper front panel. Tragically, DEC field service often removed the front panel in a later upgrade, leaving us staring at dull blank panels ever since. The PDP-11 is perhaps the most important computer in history. This was the king of all minicomputers, and once you get past the amazing front panels of the 11/20, 11/40, and 11/70, you'll find. PDP 11/70 Emulator - v3.1 August 2020. This emulator came about because years ago I was a programmer for RSTS/E on a PDP 11/45 and had admired the console idle loop light pattern - but I couldn't quite remember how it looked. Given the unavailability of real systems it became time to write an emulator This video demonstrates how one programmed a 1970's era minicomputer using switches and paper tape.

  1. The PDP-11 is a series of computers introduced in 1969 [1] by the Digital Equipment Corporation (DEC), in production there from 1970-1990. Their life-time spanned a period of momentous changes in the computer world: when they were first introduced (and for a little less than half their life), core memory was still the standard main memory technology; by the end, microprocessors had become.

The 1975 PDP-11/70 was the first computer with unix and C. But there is much more to make this an interesting minicomputer playground. The PiDP-11 uses a modified simh on a Pi, hiding behind a replica front panel. It runs everything: From Unix v5 to 2.11BSD to RSX-11, multi-user, vector graphics and all. CAD design and injection molding were new territory for me; I felt that a replica had to. The PDP-11 simulator comes courtesy of Bob Supnik's SIMH[2][3], a collection of simulators for bygone computing platforms. The aim is to put together pre-built simulator binaries along with config and OS disk images, all wrapped with neat startup scripts to make getting started simple.

Henkie's ViperPit - PDP-11

I inherited some weirdly digitized PDP-11 software from family which turned out to be some custom CAD software and drivers for an early digitizer tablet. He said he'd never been able to get it running on an emulator because of how hackish the code was but after futzing with the software and building a little cabinet extension for the PiDP-11 itself, it was like he was back in 1981 PDP-11 Processor Handbook Last Modified: January 29, 2001. This document is made up of information extracted from the LSI-11 Processor Handbook and PDP-11 Architecture Handbook. It defines the basic instruction set and addressing modes of the Digital Equipment Corporation (DEC) generic PDP-11 family of minicomputers The PDP-11/20 was the first minicomputer to interface all system elements -- processor, memory and peripherals -- to a single, bi-directional, asynchronous bus. The UNIBUS enabled fast devices to send, receive or exchange data without intermediate buffering in memory Introduction The PDP-11 instruction set offers a wide selection of operations and addressing modes.

So, he took some ideas from the set of ideas that went into the PDP-11. That does not mean that the 6800 is like a PDP-11 in any way really expressed in the ISA, just that the PDP-11 provided some inspiration or guidance.

The PDP-11/34A was introduced by DEC in 1977 as a re-enginered version of the PDP-11/34. This one is mounted in a BA11-K mounting box which provides space for one 4-slot and two 9-slot Unibus backplanes.
