Digital Equipment Corporation's founders and many of its engineers came from the post-war computing research environment of Massachusetts Institute of Technology. Ken Olsen and Harlan Anderson founded Digital Equipment Corporation (or DEC) in 1957, setting up shop in a converted 19th century woolen mill in Maynard, Massachusetts. Their financing came from the American Research and Development Corporation, a firm set up by Harvard Business School Professor Georges Doriot with the goal of finding ways to commercialize the scientific and technical innovations that came out of World War II research projects. Digital's first products were Laboratory and Systems Modules, but in 1960 they came out with the first interactive computer, the PDP-1. Digital became the first and the largest manufacturer of minicomputers in the world.


The Mill

 


Ken Olsen and Harlan Anderson founded 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 this converted 19th century woolen mill.

Laboratory Modules

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.

System Modules or "Digital Building Blocks" supplemented Laboratory Modules and were later incorporated into the PDP-1 computer. Many different types of system modules were developed and used for computers, memory testers, and other complex systems of logic.

Systems Modules

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.

Quality Control testing of Laboratory and Systems Modules

July
By the end of its first fiscal year, Digital sells $94,000 worth of Laboratory and Systems Modules and has 60 employees.

Here, Quality Control technicians test Laboratory and Systems Modules.

PDP-1 (open)

Ben Gurley worked at Lincoln Laboratory, and was the designer of the TX-0 cathode-ray tube display and light pen, which allowed the operator to interact directly with the program as it was running. Gurley left Lincoln Labs in 1959 to become one of Digital's first employees. There he designed the PDP-1, which incorporated many of the TX-0 architectural and circuit innovations.

The PDP-1, or Programmed Data Processor-1, was Digital's first 18-bit computer. Digital brought the prototype PDP-1 to demonstrate at the Joint Computer Conference in Boston in December of 1959. Bolt, Beranek and Newman (BBN), a computer consulting firm, was so impressed with the low-cost, interactive machine that they bought the prototype right off the floor. The PDP-1 featured short word length (18 bits) and high speed (5-microsecond cycle time), which made it attractive for laboratory and scientific control applications.

DEC 1500 series memory testers

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."

PDP-4 (open)

The 3000 series Laboratory Modules ran at 500 kHz. The 4000 series Systems Modules ran at 1 MHz and were principal components in the PDP-4 and PDP-5. Shown here are the modules in place in a PDP-4.

Spacewar photo

Spacewar!, developed in 1960 by Steve Russell, J.M. Graetz, and Wayne Wiitanen of MIT and played on a PDP-1, was an icon of interactive computing.


Digital's 6000 series Modules

Digital's 5000 and 6000 series Modules were made possible by the arrival of a new series of transistors. This second generation of modules ran at 10 MHz, compared to the first generation Modules which ran at 5 MHz.

Digital Logic Handbook

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.

DECUS logo

The monitor for the PDP-1 is a Type 30 point scope which measures 21"x17"x27" and weighs 120 pounds. A stylized version of the monitor became the icon for the Digital Equipment Computer Users Society (DECUS), which met for the first time in 1961. DECUS was founded on the idea of open exchange of information between user and manufacturer, and it evolved because engineers needed a forum to share information and computer programs for Digital's first computer.

PDP-4

The PDP-4 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."

Ken Olsen unveiling PDP-1 at BBN

Ken Olsen is pictured here unveiling the PDP-1 at BBN. The PDP-1 sale to BBN led to the development of shared computing time. The BBN timesharing system began operation in September of 1962.

PDP-4

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.

PDP-1

September
The PDP-1 operating system, the world's first timesharing system, is written by engineers at MIT and BBN for the PDP-1.

The PDP-1 operating system's timesharing ability made interactive access to computers economically viable by allowing various users to share the computer simultaneously. Shown here is the PDP-1 installation at BBN.

PDP-6 test

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. Shown here is a PDP-6 during testing.

PDP-5

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.

12 field service engineers

Digital has 12 field service engineers who work together to cover a territory that includes the U.S. and installations in Germany and England.

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/O device independence, a command control program and multiprocessing capabilities. Here an operator programs a PDP-6 using paper tape.

PDP-7

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). Ultimately, 120 PDP-7s were produced and sold.

DECtape

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.

magnetic core memory

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.

PDP-6, Gordon Bell, Alan Kotok (seated)

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?" Pictured is Alan Kotok seated at a PDP-6 while Gordon Bell looks on.

PDP-8/E

PDP-8/E, successor to the PDP-8/I, is introduced (shown here with contemporary footwear).

The PDP-8/E 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.

Digital introduces the TU10 magnetic tape unit.

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).

PDP-11/20

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.

VT05 video terminal

DECnet

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.

VAX-11/780

April
The VAX architecture committee meets for the first time.

The VAX Architecture Committee began work on a computer with 32-bit architecture; the goal: to build a machine which was 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. Shown here is an inside view of the first VAX model (the VAX-11/780).

VT52

September
The VT52, Digital's first commercially produced video terminal is announced.

DECstation

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.

VAX-11/780

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 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.

Digital Diagnosis Center in Colorado Springs

Digital opens the Digital Diagnosis Center (DDC) in Colorado Springs, Colorado. It is the industry's first facility for computerized remote diagnosis.

 

ARPAnet

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 as the ARPAnet, a wildly successful wide-area packet switching network that later evolved into the Internet. By 1970, the initial four-node configuration was complete, consisting of UCLA, UC Santa Barbara, Stanford Research Institute and the University of Utah. From these four sites, 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.
