Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by Digital Equipment Corporation ( DEC ), designed to replace the 32-bit VAX complex instruction set computer ( CISC ) ISA and its implementations.

Alpha was implemented in microprocessors originally developed and fabricated by DEC.

Kermit was developed at Columbia University in 1981 to allow students to transfer files between IBM or DEC DECSYSTEM-20 mainframe computers and removable media on microcomputers ( initially Intertec Superbrains running CP / M ).

MUMPS was developed with the support of a government research grant, and so MUMPS was released to the public domain ( no longer a requirement for grants ), and was soon ported to a number of other systems including the popular DEC PDP-8, the Data General Nova and the DEC PDP-11 and the Artronix PC12 minicomputer.

Over time, some PDP-10 operators began running operating systems assembled from major components developed outside DEC. For example, the main Scheduler might come from one university, the Disk Service from another, and so on.

DEC developed the 16-bit PDP 11 as a response to the introduction of the Data General NOVA, which had a 16-bit word length ; DEC's previous PDP-8 had only 12 bit words.

Andrew Tridgell developed the first version of Samba Unix in December 1991 and January 1992, as a PhD student at the Australian National University, using a packet sniffer to do network analysis of the protocol used by DEC Pathworks server software.

The SA-1100 was a derivative of the SA-110 developed by DEC.

The SA-1500 was a derivative of the SA-110 developed by DEC initially targeted for set-top boxes.

UCSD Pascal was developed at The University of California, San Diego Institute for Information Systems in 1978 to provide students with a common operating system that could run on any of the then available microcomputers as well as campus DEC PDP-11 minicomputers.

The router was later moved to the Palo Alto Internet Exchange, or PAIX, which was developed and operated by Digital Equipment Corporation ( DEC ).

Symbolics developed a Genera version, named Open Genera, that included a virtual machine that enabled executing Genera on DEC Alpha based workstations, plus several Genera extensions and applications that were sold separately ( like the Symbolics S-Graphics suite ).

' СМ ЭВМ ' is the name of DEC compatible computers developed in USSR ( although not all of the СМ ЭВМ was compatible with PDP-11 ).

Finally, CompuServe developed its own packet switching network, implemented on DEC PDP-11 minicomputers acting as network nodes that were installed throughout the US ( and later, in other countries ) and interconnected.

The PDP-6 ( Programmed Data Processor-6 ) was a computer model developed by Digital Equipment Corporation ( DEC ) in 1963.

One of the most influential programs developed at DEC was Decision Point, a management gaming simulation, which won the Nebraska Video Disc Award for Best of Show in 1985.

The Action Agenda advocates an ecosystem-based approach to watershed management and it was developed by the NY DEC in collaboration with a number of stakeholders in the basin with public input.

Dynamic Debugging Technique, or DDT, was the name of several debugger programs originally developed for DEC hardware, initially known as DEC Debugging Tape because it was distributed on paper tape.

RSTS ( pronounced as " RIST-ess " or " RIST-uhs ") is a multi-user time-sharing operating system, developed by Digital Equipment Corporation (" DEC "), ( now part of Hewlett Packard ) for the PDP-11 series of 16-bit minicomputers.

The first version of RSTS ( RSTS-11, Version 1 ) was implemented in 1970 by DEC software engineers that developed the TSS-8 time-sharing operating system for the PDP-8.

The commercial timesharing services such as CompuServe, On-Line Systems ( OLS ), and Rapidata maintained sophisticated inhouse systems programming groups so that they could modify the operating system as needed for their own businesses without being dependent on DEC or others.

There is a free public boat launch maintained by the DEC on the north end of the middle lake with parking for vehicles and trailers, though the lakes are small enough to be paddled or rowed, and motor boat speed through much of the middle lake is limited to.

For a time, a commercial compiler called CM3 maintained by one of the chief implementors prior at DEC SRC who was hired before DEC being sold to Compaq, an integrated development environment called Reactor and an extensible Java Virtual Machine ( licensed in binary and source formats and buildable with Reactor ) were offered by Critical Mass, Inc., but that company ceased active operations in 2000 and gave some of the sources of its products to elego Software Solutions GmbH.

A map showing these holdings was released by the DEC in 2008 ; the map shows the location of three foot trails maintained by the DEC and one by the Izaak Walton League.

Early IMP compilers were developed for the ICL System 4, UNIVAC 1108, IBM 360, DEC PDP-9, DEC PDP-15 and CTL Modular One computers.

* A very High resolution monochrome video card with blitter and hardware text line and arc drawing capability, was designed for CAD applications, based on the NEC µPD7220 chip designed for graphic terminals, but was also used by some personal computers like the DEC Rainbow, and notably also for the Tulip System I.

Notably, the design team was led by Dirk Meyer, who had worked as a lead engineer on multiple Alpha microprocessors during his employment at DEC. Jerry Sanders had approached many of the engineering staff to work for AMD as DEC wound down their semiconductor business, and brought in a near-complete team of engineering experts.

As a result of its free availability, knowledge of BASIC became relatively widespread ( for a computer language ) and BASIC was implemented by a number of manufacturers, becoming fairly popular on newer minicomputers like the DEC PDP series and the Data General Nova.

Early implementations were for the DEC PDP-7 and PDP-11 minicomputers using early Unix, and Honeywell 36-bit mainframes running the operating system GCOS.

; Open Genera: for DEC Alpha.

Digital Equipment Corporation ( DEC ) further reduced cost for mass-produced minicomputers, and mapped peripherals into the memory bus, so that the input and output devices appeared to be memory locations.

The newly christened DEC received $ 70, 000 from AR & D for a 70 % share of the company, and began operations in a Civil War era textile mill in Maynard, Massachusetts, where plenty of inexpensive manufacturing space was available.

DEC used the Systems Modules to build their " Memory Test " machine for testing core memory systems, selling about 50 of these pre-packaged units over the next eight years.

DEC hit an even lower price-point with the PDP-8 / S, the S for " serial ".

DEC then used the new PDP-8 design as the basis for a new LINC, the two-processor LINC-8.

Package for DEC Alpha AXP 21064 Microprocessor

These microprocessors were most prominently used in a variety of DEC workstations and servers, which eventually formed the basis for almost all of their mid-to-upper-scale lineup.

A persistent report attributed to DEC insiders suggests the choice of the AXP tag for the processor was made by DEC's legal department, which was still smarting from the VAX trademark fiasco.

The " DIX-group " with Gary Robinson ( DEC ), Phil Arst ( Intel ), and Bob Printis ( Xerox ) submitted the so-called " Blue Book " CSMA / CD specification as a candidate for the LAN specification.

*" Janus " was a codename used for Microsoft Windows 3. 1x and Windows 2000 ( DEC Alpha and Itanium 64-bit editions )

He quit DEC in 1979 and began writing full-time, moving to Orlando, Florida, for a year where he met his third wife Jackie.

In 1990, he resumed his university studies, and was exposed to UNIX for the first time, in the form of a DEC MicroVAX running ULTRIX.

In 1978 Roy Trubshaw, a student at Essex University in the UK, started working on a multi-user adventure game in the MACRO-10 assembly language for a DEC PDP-10.

Later, Systems Concepts attempted to produce a compatible replacement for the DEC PDP-10 computers.

The portability was soon useful, as MUMPS was shortly adapted to a DEC PDP-15, where it lived for some time.
