> 1957 | August: Ken Olsen and Harlan Anderson found DIGITAL EQUIPMENT CORPORATION and set up shop in an old woolen mill in Maynard, Massachusetts. DIGITAL opened for business with three employees and 8,500 square feet of production space in a converted 19th century woolen mill.
> 1957 | The company’s first product is Laboratory Modules. Laboratory Modules were intended to sit on an engineer’s workbench or be mounted in a scientist’s equipment rack. To simplify the construction of logic systems, the modules were connected by simple cords with banana plugs.
> 1958 | February: DIGITAL’s second product, Systems Modules, goes on the market. Systems Modules or "DIGITAL Building Blocks" were identical in circuitry, signal levels, and speed range to Laboratory Modules but had a higher packing density and fixed backplane wiring. They were used for computers, memory testers and other complex systems of logic.
> 1958 | July: By the end of its first fiscal year, DIGITAL sells $94,000 worth of laboratory and systems modules and has 60 employees.
> 1959 | Design work begins on DIGITAL Memory Test Systems. From a DIGITAL technical report dated March 1960: "DEC1500 series memory testers -- complete systems for testing coincident current core memories under simulated computer conditions. DEC memory testers will test planes up to 64 by 64 with several patterns of information quickly and completely in a single operation."
> 1959 | The 3000 series Laboratory Modules and 4000 series Systems Modules go on the market. The 3000 series Laboratory Modules ran at 500 kHz. The 4000 series System Modules ran at 1 MHz and were principal components in the PDP-4 and PDP-5.
> 1959 | August: Design work begins on DIGITAL’s first computer, the Programmed Data Processor-1 (PDP-1). A young hardware engineer named Ben Gurley was hired to design DIGITAL’s first computer. Three and a half months later, the prototype Programmed Data Processor-1 (PDP-1) was complete. In December, the prototype was demonstrated at the Joint Computer Conference in Boston.
> 1960 | The 5000 series Laboratory Modules and 6000 series Systems Modules go on the market. DIGITAL’s second-generation modules were made possible by the arrival of a new series of transistors. The modules ran at 10 MHz, compared to the first-generation modules, which ran at 5 MHz.
> 1960 | The first DIGITAL Logic Handbook is published. The Logic Handbook was an early project of Barbera Stephenson, the first woman hired as an engineer at DIGITAL. The Logic Handbook was the first in a long series of handbooks that worked both as textbooks and promotional tools. DIGITAL sent them to every customer and handed them out at trade shows.
> 1960 | November: The PDP-1, the world’s first small, interactive computer is delivered to Bolt, Beranek and Newman (BBN), a computer-consulting firm in Cambridge, Massachusetts. From a technical bulletin dated March 1960: "…a compact, solid state general purpose computer with an internal instruction execution rate of 100,000 to 200,000 operations per second. PDP-1 is a single address, single construction, stored program machine with a word length of 18-bits operating in parallel on 1’s complement binary numbers."
> 1961 | Gordon Bell begins design work on the PDP-4. The machine was aimed at applications with not many calculations, but rather the single manipulation of input and output, such as controlling a bakery or fleet of elevators. "As computers [like the PDP-4] become smaller and less expensive," said Bell, "they will take over some special system types…then the computer becomes a ‘module’ of the system."
> 1961 | DECUS, the DIGITAL Equipment Computer Users Society, meets for the first time in Lexington, Massachusetts. DECUS evolved because engineers needed a forum to share information and computer programs for DIGITAL’s first computer, the PDP-1. Founded on the idea of open exchange of information between user and manufacturer, DECUS has grown to be the computer industry’s largest users’ group with 150,000 members in 22 chapters worldwide. The DECUS logo is a stylized version of the PDP-1 "TYPE 30" point scope.
> 1962 | July: Shipments begin of the PDP-4, DIGITAL’s second 18-bit computer. Similar in structure to the PDP-1, the PDP-4 used slower memory and different packaging to achieve a lower price of $65,000. Approximately 54 PDP-4s were sold in application areas as diverse as nuclear physics, production and stock control.
> 1962 | September: The PDP-1 operating system (the world’s first timesharing system) was written by engineers at MIT and BBN for the PDP-1. Timesharing made interactive access to computers economically viable by allowing various users to share the computer simultaneously.
> 1962 | Gordon Bell begins design work on the architecture for the PDP-5. Bell based the new machine on a 12-bit DIGITAL controller (the DC-12) that DIGITAL had designed in 1961 but never built. Bell specified the instruction set in the fall of 1962. Design work was continued by Edson deCastro in early 1963.
> 1963 | The 8000 series modules are introduced. The 8000 series modules, also known as VHF modules, ran at 30 MHz. The modules were used to build high performance systems. The technology developed in the VHF modules was used in the timesharing capabilities of the PDP-6.
> 1963 | April: DIGITAL’s first 12-bit machine, the PDP-5, is announced. The PDP-5 was innovative in replacing the radial structure of earlier designs with an I/O bus. By allowing peripheral equipment to be added incrementally – rather than pre-allocating space, wiring, and cable drivers – the I/O bus design lowered the base costs of the system and simplified the configuring of machines in the field.
> 1963 | DIGITAL has 12 field service engineers who work together to cover a territory that includes the U.S. and installations in Germany and England. In March, DIGITAL opened its first European sales and service office with three people in Munich, Germany. At the same time, the first Canadian sales office opened with two people in Ottawa.
> 1964 | Flip Chip modules are developed. Flip Chip modules were built of discrete transistors, diodes, resistors and capacitors. The series was designed so that backplanes could be wire-wrapped automatically, reducing costs and increasing production line throughput. Flip Chips became the basis for the PDP-8.
> 1964 | July: The first European Customer Training Center opens in Reading, England.
> 1964 | October: DIGITAL unveils its first 36-bit computer, the PDP-6. DIGITAL’s first large computer, the PDP-6, was designed to be a powerful, timeshared machine oriented to scientific use. It was the first commercially available computer with manufacturer-provided software for general purpose applications. Ultimately, 26 PDP-6 systems were installed.
> 1964 | TOPS-10 is developed as the major user software interface for DIGITAL’s 36-bit machines. TOPS-10 was developed from a 6-K word monitor for the PDP-6. It included user files and I/0 device independence, a command control program, and multiprocessing capabilities.
> 1964 | December: The PDP-7, DIGITAL’s third 18-bit computer, is introduced. A successor to the PDP-4, the PDP-7 used smaller, more conventional system units and was well-received in laboratory and data acquisition applications. The machine featured DIGITAL’s first mass-storage based operating system (DECsys for DECtape). In 1969, Richie and Thompson used the PDP-7 to develop the first version of UNIX at Bell Labs. Ultimately, 120 PDP-7s were produced and sold.
> 1964 | DECtape is introduced concurrent with the PDP-7. DECtape was a random access, block addressable medium for storing information on small magnetic tape. For the first time, tape was divided into sectors so that it could be used as an I/O storage system that was both interactive and inexpensive.
> 1964 | December: DIGITAL is issued its first patent, for magnetic core memory. The inventors are Ken Olsen and Dick Best. By 1971, DIGITAL was the largest consumer of magnetic core memories other than IBM. DIGITAL built its own magnetic core manufacturing business and by the mid- 1970s was producing 30 billion magnetic cores per year.
> 1965 | The PDP-7A is introduced. This second version of the PDP-7 used the newly announced R Series Flip Chip modules.

> 1965

> April: Introduction of the PDP-8, the world’s first mass-produced minicomputer.

> Specifications:
> Word length: 12 bits
> Speed: 1.5-microsecond cycle time
> Primary memory: 4K 12-bit word core memory
> Secondary memory: 32K maximum
> Instruction set: 3-bit op code, 1 indirect bit; 8 bits of address
> Input/Output: teletype (ASR-33) includes paper-tape reader and punch
> Power: 780 watts
> Price: $18,000

> 1965 | November: In what is believed to be the earliest example of around-the-world networking, a link is made by operating a PDP-6 in Perth, Australia from Boston via a telex link. The PDP-6 was operated and programmed from Boston using a 12,000-mile, 5-hole telex code. It proved very difficult to generate a control C in 5-hole code. At one point in the session, Robin Frith in Perth asks Alan Kotok in Massachusetts, "Do you think you could let us poor Aussies have a bit of core?"
> 1966 | August: The PDP-9, DIGITAL’s fourth 18-bit computer system ships. The PDP-9 featured a speed increase of approximately twice that of the PDP-7. The PDP-9 was also one of the first small or medium scale computers to have a keyboard monitor system based on DIGITAL’s own small magnetic tape units (DECtape).
> 1966 | The PDP-8/S is introduced as an economical alternative to the "classic" PDP-8. The size of a file-cabinet drawer, the S model’s cost reduction came from implementing the PDP-8 instruction set serially.
> 1966 | The LINC-8 is introduced. The LINC-8 was based on a previous design from Lincoln Labs to penetrate the emerging biomedical computer market. The computer incorporated both the LINC (Laboratory Instrument Computer) processor and the PDP-8 processor unit.
> 1967 | September: The PDP-10 debuts. The 36-bit PDP-10 was program-compatible with the PDP-6 and approximately twice as powerful. Designed to perform conversational timesharing, batch-processing and real-time operations equally well and simultaneously, the PDP-10 achieved great popularity with the commercial timesharing utilities, university computer centers and research laboratories.
> 1967 | K series Flip Chip modules are introduced. This new line of noise-immune modules was used for control applications in industrial computers. By 1975, DIGITAL produced approximately 200 different types of K series modules.
> 1967 | The first generation of M series Flip Chip modules is introduced. M series modules were used in the first redesign of the PDP-8, called the PDP-8/I, and were used in the first PDP-11 (PDP-11/20), the second PDP-10 processor (KI10) and the PDP-8/E. M series modules were DIGITAL’s first logic cards to use integrated circuits.
> 1968 | July: There are more than 50 sales and services offices in 11 countries all over the world.
> 1968 | August: The PDP-8/I is DIGITAL’s third 12-bit computer system and the first to be implemented with integrated circuits. The PDP-8/I was more expandable (and expensive) than the PDP-8/S. Introduced at the same time was the PDP-8/L, a smaller OEM version of the 8/I.
> 1968 | EDUsystems are introduced. PDP-8-based EDUsystems, using the BASIC language developed by Dartmouth College, brought computers into elementary and secondary schools. EDUsystems were designed to start small and expand as the school’s computing requirements increased.
> 1968 | The TYPESET-8, the pioneer of the "turnkey" computer system, is introduced. This hardware and software package originally sold with the classic PDP-8 as its CPU and functioned as a computerized typesetting system for use in hot metal and photocomposition typesetting.
> 1969 | March: The PDP-14 is delivered. K series modules were used to develop noise-immune I/O units for this completely new, solid state controller that controlled operations by solving Boolean equations. Applications in the relay-logic marketplace included an automatic racking and stacking system, control of machine tools and sequencing.
> 1969 | The PDP-12, successor to the LINC-8, is introduced. PDP-12 was used in applications such as chemistry, applied psychology, patient monitoring and industrial testing. The machine incorporated the PDP-8/I and LINC-8 instruction sets, making it compatible with LINC-8 software. In addition to a display-based operating system, software packages were included for data acquisition and display, Fourier analysis and spectrometry.
> 1969 | The PDP-15, successor to the PDP-9 and 9/L, is introduced. The PDP-15 was DIGITAL’s last 18-bit computer system and the first implemented with integrated circuits. The new machine was faster and less expensive than its predecessors and had the added sophistication of a separate I/O processor to the CPU. Over 400 of these machines were ordered in the first eight months of production.
> 1969 | FOCAL version 1.0 is issued. The name stood for FOrmula CALculator and was the company’s first registered international trademark. FOCAL was the only language that ran on every DIGITAL computer at the time.
> 1970 | The PDP-8/E, successor to the PDP/8-I, is introduced. The new computer featured the OMNIBUS – a patented synchronous bus that handles bi-directional communication between system elements. A single OMNIBUS contained enough slots to handle up to 32K words of core memory, or up to 10 peripheral controllers. Shortly after the introduction of the PDP-8/E, DIGITAL installed its 10,000th computer system.
> 1970 | April: The PDP-11/20, the first of DIGITAL’s 16-bit family of machines, is delivered. 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. The PDP-11 became the world’s most successful family of minicomputers.
> 1970 | DIGITAL introduces three new peripherals: the LA30 DECwriter, the TU10 magnetic tape unit and the VT05 alphanumeric keyboard terminal. The VT05 was the first video terminal manufactured by DIGITAL. The TU10 DECmagtape unit was available in eight different models. Each model incorporated a transport mechanism, head assembly, read/write electronics, motor control circuits, power supply, and cabinet. Bit packing densities of 200, 556, and 800 bits per inch (bpi) were program selectable. A single capstan drove the tape in the forward or reverse direction at a speed of 45 inches per second (ips).
> 1970 | MUMPS software for the PDP-15 is introduced. MUMPS was developed as a general purpose data management language at Massachusetts General Hospital; it allowed up to twenty-two users to simultaneously access a database held on disk. MUMPS-15 systems were used extensively in such areas as hospital information and stock and warehouse control.
> 1971 | June: The first annual customer satisfaction survey is taken.
> 1971 | RSTS-11, a timesharing operating system for the PDP-11, is introduced. RSTS-11 was the first general purpose small computer operating system with generalized device handling. RSTS-11 was particularly well suited to commercial applications because of its sophisticated file handling and protection capabilities.
> 1971 | The DECsystem-10 is introduced, marking a change in the marketing philosophy of the PDP-10 group. The entire DECsystem-10 line used the same basic monitor system to give users unequaled expansion capability. The first DECsystem10s, the 10/40 and 10/50, used the proven KA10 processor, which was developed for the PDP-10 in 1967.
> 1971 | The PDP-11/45, the most powerful PDP-11 family member to that point, is introduced. The PDP-11 was featured in Garry Trudeau’s Doonesbury comic strip. The PDP-11/45 was an excellent computational tool for large multi-user, multi-task installations. Through memory management, memory could be expanded to 128K, which included a combination of bi-polar and MOS memory. Other features included a greatly expanded floating-point processor.
> 1971 | Doonesbury’s Mark Slackmeyer learns to operate a PDP-11 during an ill-fated summer job.
> 1971 | The RTM (PDP-16) is introduced. The RTM (Register Transfer Module) began a new concept in small computers and digital controllers. Announced initially as the PDP-16, this series of printed circuit modules could be tailored to any application and made to operate with or without programs. In terms of cost, the RTM closed the gap between small logic modules and the smallest general purpose computer.
> 1972 | The PDP-16/M is introduced as the first "sub-minicomputer" developed by DIGITAL. The PDP-16/M combined the programmable capability of a minicomputer with the proven reliability of the PDP-16 controller (RTM). The machine incorporated a programmable read-only memory and a variety of options to make a versatile device for the OEM, educator and systems designer.
> 1972 | The PDP-11/40 is introduced. The PDP-11/40 offered approximately twice the processing power of the earlier PDP-11/20. A floating-point package was offered as on option, making the cost slightly lower than the 11/20.
> 1972 | DIGITAL introduces the PDP-11/05 and PDP-11/10, the first "inexpensive" PDP-11s. The central processors for the PDP-11/05 and 11/10 were identical. The 11/05 was offered for the Original Equipment Manufacturer, while the 11/10 was designed for the end-user. Both machines offered features not available on the earlier PDP-11/20, such as 4-level priority interrupt and multiple accumulators.
> 1972 | May: The KI10 processor is introduced for the DECsystem-10/70. The KI10 processor was faster than its predecessor, the KA10, and was DIGITAL’s first 36-bit processor to incorporate integrated circuits. The lights on the KI10 were later used to represent a futuristic computer in George Lucas’ landmark film, THX1138.
> 1973 | May: RSX-11D, a real-time operating system for online data acquisition, monitoring and control on the PDP-11, is introduced. RSX-11D was aimed at the sophisticated end-user and included a real-time executive, on-line program development, complete device handling capabilities and total system protection. Typical applications were in the lab, industrial, computation and OEM markets.
> 1973 | July: RT-11, a real-time operating system for monitoring and control, is introduced. RT-11 signaled DIGITAL’s entrance into the low end of the real-time market. With its single-job monitor and F/B monitor, RT-11 was designed for the single-user involved in program development and/or real-time applications, providing fast, simple, on-line access to any PDP-11 processor with at least 8K of memory and mass storage.
> 1973 | September: DIGITAL develops DEC Data Communications Message Protocol (DDCMP) as a standard for its future computer-to-computer communications. DDCMP, which was used to develop DIGITAL’s Network Architecture (DECnet), was based on peer-to-peer communications where information is managed by members of the networks itself; communication is from processor to processor, rather than from processor to terminal.
> 1974 | April: MPS, DIGITAL's first microprocessor, is introduced. MPS represented DIGITAL’s first entry into LSI (Large-Scale Integration) technology. MPS modules were designed to supply users with reliable, low-cost microprocessor systems that could be used in process/control and data formatting or preprocessing applications.
> 1974 | May: RSX-11M, a real-time operating system for online control, is introduced for use on the PDP-11. RSX-11M was a real-time, multi-programming, program-development system with a disk-based operating system supporting both synchronous and asynchronous communications hardware. RSX-11M concepts were precursors to those in the VMS operating system.
> 1974 | September: DIGITAL announces the LA36 DECwriter II. The LA36 DECwriter II was the company’s first commercially successful keyboard terminal and became the de facto market standard.
> 1974 | October: The KL10 processor is introduced in the DECsystem-10/80 and 10/90. Twice as fast as its predecessor, the KI-10, and four times as fast as the earlier KA-10, the KL-10 featured 386 micro-programmed instructions, emitter coupled logic (a state-of-the-art technology) and a 125 nanosecond access time cache or buffer memory. One of the more significant features of the KL-10 was the Console Diagnostic Computer, which uses a PDP-11/40 to perform those functions.
> 1975 | February: LSI-11, DIGITAL's first 16-bit microcomputer, is introduced. Directed toward OEM’s and large volume end-users whose applications require the computer to be buried inside the final applications product, the LSI-11 was a complete computing system (CPU, memory and I/O) on one board.
> 1975 | February: The powerful PDP-11/70 is added to the PDP-11 family. The PDP-11/70 represented the high end of PDP-11 architecture with the capacity for supporting the speed, addressing range and bandwidth required in large systems applications. It was the first PDP-11 to use cache memory.
> 1975 | April: Introduction of DIGITAL's Network Architecture (DECnet). DECnet architecture evolved from one focused on the RSX family of operating systems to an architecture that encompasses large, open, distributed networks. Unlike competitors’ network offerings, DECnet was not a terminal network but a true computer-to-computer capability for distributed computing systems.
> 1975 | April: The VAX architecture committee meets for the first time. Work begins on a computer with 32-bit architecture; the goal: to build a machine culturally compatible to the PDP-11 -- but with increased address space. The result: VAX, the "Virtual Address Extension" of the PDP-11’s 16-bit architecture to 32-bit architecture. The new computer required a new operating system, so VMS, the "Virtual Memory System" was developed simultaneously.
> 1975 | September: The VT52, DIGITAL first commercially produced video terminal is announced. The VT52 was designed to sell into programming, timesharing and text editing applications. The terminal included a 19-key numeric cluster pad for data entry plus four cursor control keys and three unlabeled function keys to transmit escape sequences which could be used by the customer for special functions.
> 1975 | The PDP-11/34 is delivered. The midrange PDP-11/34 was DIGITAL’s most successful PDP-11 in terms of unit volume. The 11/34 featured a CPU so compact that the entire CPU logic was contained on two circuit boards. This provided greater flexibility during later system expansion by making additional chassis space available.
> 1976 | January: Introduction of 36-bit DECSYSTEM-20, the lowest-priced general-purpose timesharing system on the market. The DECSYSTEM-20 was based on the non-cache KL20 processor, 64 to 256K 36-bit core memory and included RP04 moving head disk drives, TU45 tapes, a line printer, a card reader and 8 to 64 terminal lines.
> 1976 | January: TOPS-20, a new virtual memory operating system, is introduced for use with the DECSYSTEM-20. TOPS-20 (the direct descendant of TOPS-10) was implemented with upgraded facilities based on multi-process operating systems advances, including concurrent interactive timesharing and multi-stream batch. TOPS-20 was also available with variety of unbundled higher level language compilers and application tools such as FORTRAN, COBOL, BASIC, ALGOL, CPL, APL and Data Base Management.
> 1976 | DIGITAL enters the word-processing market with the WPS-8. The WPS-8 was a stand-alone, single terminal, single user word processing system, the first in a series of products designed to address the needs of "sophisticated" users of text editing equipment.
> 1977 | March: DIGITAL announces a new midrange price/performance system, the PDP-11/60. The PDP-11/60 offered a combination of unique attributes, which were normally found in larger, more expensive computers at the time. Designed around the proven UNIBUS architecture, the PDP-11/60 included user control store features previously unavailable from DIGITAL, as well as several 11/70 class features such as cache memory and RAMP.
> 1977 | May: DIGITAL announces its newest computer, the DECstation, a family of components centered around the VT78 Video Data Processor. The DECstation was a complete PDP-8 computer system implemented in large-scale integration technology so that it could be packaged inside the shell of a display terminal. Designed for an interactive environment, the primary emphasis was on system capability, hence the large 16K (32Kb) memory and the array of I/O controllers.
> 1977 | October: Introduction of the VAX-11/780, the first member of the VAX computer family. VAX-11 architecture was designed to alleviate the PDP-11’s most severe limitation: an address space that was too small for many applications. The Virtual Address eXtension (VAX) increased the virtual address from 16 to 32 bits. The number of general registers also doubled from 8 to 16. The instruction set had both two and three operand formats for many common operations, with either a register or memory operand allowable.
> 1977 | DIGITAL opens the DIGITAL Diagnosis Center (DDC) in Colorado Springs, Colorado. It is the industry's first facility for computerized remote diagnosis.
> 1977 | DIGITAL is the first computer company to connect to the ARPAnet. The connection is made via a PDP-10. In 1969, the U.S. Defense Department’s Advanced Research Projects Agency (ARPA) began to construct a resource sharing computer network among its contractors. This network became known at the ARPAnet, a wildly successful wide-area packet switching network that later evolved into the Internet. By the end of 1970, the initial four-node configuration was complete consisting of UCLA, UC Santa Barbara, Stanford Research Institute and the University of Utah. The ARPANET expanded steadily and operated with a wide variety of hardware and software systems. From the four sites that comprised the network in January 1970, the network expanded to thirteen by January 1971 and twenty-three by April 1972. By the time that DIGITAL joined as the first computer company in 1977, there were approximately 60 nodes in operation.
> 1978 | February: V1.0 of the VMS operating system ships. VMS (Virtual Memory System) was developed in parallel with the VAX, allowing complete integration of hardware and software. The overall aim during development was to achieve compatibility between systems so that information and programs could be shared. V1.0 featured FORTRAN IV and DECnet, a 64 megabyte memory limit, an event driven priority scheduler, process swapper, process deletion/creation/control, I/O post processing and AST delivery.
> 1978 | March: DIGITAL ships the first DECsystem 2020. The DECsystem-2020 was introduced as "the world’s lowest cost mainframe computer system." It was DIGITAL’s least expensive and last 36-bit computer system. The system’s low cost was made possible by a state-of-the-art packaging technology that allowed the entire system to fit in a single cabinet measuring five feet high by two feet wide by three feet deep.
> 1978 | August: The VT100 terminal is introduced. The VT100 was DIGITAL’s first ANSI-compliant video terminal. It became the industry’s best selling terminal and the de facto market standard.
> 1978 | September: Gordon Bell, Craig Mudge and John McNamara publish Computer Engineering: A DEC View of Hardware Systems Design. The book provides a case study of computer design at DIGITAL within the context of prevailing goals and constraints. For the first time, the computer industry was examined from an evolutionary perspective.
> 1979 | March: The F-11 microprocessor is announced. The F-11 was DIGITAL’s second 16-bit – and first internally designed – microprocessor. The F-11 shipped in the LSI-11/23 board.
> 1979 | March: The PDP-11/23 is introduced. The PDP-11/23 was positioned between the low-end PDP-11/03 and the PDP-11/34 in order to round out DIGITAL’s 16-bit product line and bridge the gap between existing microcomputers and midrange minicomputers.
> 1979 | November: The RL02 disk drive is announced. The RL02 featured twice the capacity of the RL01 drive and low ambient noise levels for office use.
> 1979 | November: The PDP-11/44 ships. The PDP-11/44 incorporated the complete PDP-11/70 instruction set and memory expansion into 1MB and a lower-cost package. The PDP-11/44 was the last PDP-11 implemented in discrete logic.
> 1980 | February: Introduction of DECnet Phase III – the most advanced networking in the computer industry. DECnet products made it possible to build networks of over 200 nodes, considered very large in 1980. Phase III was supported on seven operating systems and three hardware families.
> 1980 | April: VMS version 2.0 is released. VMS version 2.0 offered the industry’s largest array of languages on one system including VAX-11, FORTRAN, BASIC, PASCAL, COBOL-74 and PL/I, DSM and PDP-11 CORAL 66/VAX.
> 1980 | June: DIGITAL, Intel and Xerox cooperate in Ethernet local area network project. The DIGITAL LAN products that built on Ethernet technology allowed minicomputer, terminal servers and network devices to be connected with ease.
> 1980 | October: Introduction of the VAX-11/750. VAX-11/750 was the second member of the VAX family and the industry's first Large Scale Integration (LSI) 32-bit minicomputer.
> 1980 | October: The RM80 disk is introduced. The medium-capacity RM80 disk drive was DIGITAL’s first product based on Winchester technology, incorporating advanced microprocessor control and industry leadership RAMP features.
> 1981 | March: The PDP-11/24 is introduced. The PDP-11/24 was a fourth generation PDP-11 system designed to increase DIGITAL’s penetration of the Technical and Commercial OEM markets. The new machine featured large-scale integration, 1 MB memory capacity and the PDP-11 UNIBUS.
> 1981 | July: DIGITAL announces the VT125 Graphics Terminal, the newest member of the VT100 terminal family. The VT125 was an enhanced VT100 alpha-numeric terminal with data plotting extensions which combined bit map graphics architecture, automatic vector and general curve generation, as well as alphanumeric features to produce a state-of-the-art terminal suitable for business graphics and technical applications.
> 1981 | July: DIGITAL announces the DECmate "Work Processor." With the DECmate, DIGITAL integrated an array of functions such as word processing, communications, financial planning, budgeting support and engineering calculations in a single marketing focus. The DECmate was based on the VT278 computing terminal, which combined video output and keyboard input with a powerful programmable CPU and peripheral interfaces all on one module.
> 1981 | October: VAX information architecture is introduced. VAX information architecture consisted of a family of information management software products including VAX-11 FMS, DATATRIEVE, CDD, RMS and DBMS.
