Mr. Devey first came to Sprague in 1953 as a Product Specialist in the Field Engineering Department, coming from the Office of Naval Research in Washington, D. C., where he was an electronic scientist engaged in undersea warfare studies.

During the first pass of Phase 3,, references to the actual addresses of index words and electronic switches are collected and the availability table is updated.

The first two methods apply to both index words and electronic switches ; ;

It will not, however, be used for symbolic assignment until all other index words or electronic switches have been assigned for the first time.

J. Presper Eckert and John W. Mauchly similarly were not aware of the details of Babbage's Analytical Engine work prior to the completion of their design for the first electronic general-purpose computer, the ENIAC.

The Atanasoff – Berry Computer ( ABC ) was the first electronic digital computing device.

Atanasoff and Clifford Berry's computer work was not widely known until it was rediscovered in the 1960s, amidst conflicting claims about the first instance of an electronic computer.

At that time, the ENIAC was considered to be the first computer in the modern sense, but in 1973 a U. S. District Court invalidated the ENIAC patent and concluded that the ENIAC inventors had derived the subject matter of the electronic digital computer from Atanasoff ( see Patent dispute ).

George W. Snedecor, the head of Iowa State's Statistics Department, was very likely the first user of an electronic digital computer to solve real world mathematics problems.

Judge Larson explicitly stated, " Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr. John Vincent Atanasoff ".

The Lynx holds the distinction of being the world's first handheld electronic game with a color LCD.

The Lynx was the second handheld game with the Atari name to actually be produced, the first was Atari Inc .' s handheld electronic game Touch Me.

However, the possibility of actually constructing a conscious machine was probably first discussed by Ada Lovelace, in a set of notes written in 1842 about the Analytical Engine invented by Charles Babbage, a precursor ( never built ) to modern electronic computers.

The first true electronic vacuum tubes, invented around 1906, used this hot cathode technique, and they superseded Crookes tubes.

The field of computer music can trace its roots back to the origin of electronic music, and the very first experiments and innovations with electronic instruments at the turn of the 20th century.

The first component of the term comes from " cybernetics ", which is derived from the Greek κυβερνήτης ( kybernētēs, steersman, governor, pilot, or rudder ), a word introduced by Norbert Wiener for his pioneering work in electronic communication and control science.

The first solid state electronic calculator was created in the 1960s, building on the extensive history of tools such as the abacus, developed around 2000 BC ; and the mechanical calculator, developed in the 17th century.

The first truly pocket-sized electronic calculator was the Busicom LE-120A " HANDY ", which was marketed early in 1971.

Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit ( then proclaimed as a " calculator on a chip "), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries.

Summer would become the first well-known and most popular disco artist — eventually having the title " The Queen of Disco " bestowed upon her by various critics — and would also play a part in pioneering the electronic sound that later became a prominent element of disco.

Diodes were the first semiconductor electronic devices.

The first programmable computer built by Konrad Zuse used binary notation for numbers.

It has the distinction of being the first programmable ROM cartridge – based video game console, and the first console to use a microprocessor.

The HP-65, the first programmable pocket calculator

The first desktop programmable calculators were produced in the mid-1960s by Mathatronics and Casio ( AL-1000 ).

The first programmable pocket calculator was the HP-65, in 1974 ; it had a capacity of 100 instructions, and could store and retrieve programs with a built-in magnetic card reader.

In 1979, HP released the first alphanumeric, programmable, expandable calculator, the HP-41C.

The first Soviet programmable desktop calculator ISKRA 123, powered by the power grid, was released at the beginning of the 1970s.

The first Soviet pocket battery-powered programmable calculator, Elektronika " B3-21 ", was developed by the end of 1977 and released at the beginning of 1978.

The need to break German codes in World War II led to advances in cryptography and theoretical computer science, with the first programmable digital electronic computer being developed at England's Bletchley Park.

In 1941 Konrad Zuse presented the Z3, the world's first fully functional and programmable computer using electromechanical parts.

In 1943 Tommy Flowers designed and built the Colossus, the world's first fully functional, electronic, digital and programmable computer.

The first programmable computer, the Z3 ( computer ) | Z3 included floating point arithmetic ( replica on display at Deutsches Museum in Munich ).

In 1938, Konrad Zuse of Berlin completed the Z1, the first mechanical binary programmable computer, this was however unreliable in operation.

Konrad Zuse, architect of the first programmable computer, which used 22-bit binary floating point.

The underlying principle was noted by the inventor of the first programmable computing device design:

Colossus was the world's first electronic programmable computing device.

Though the ABC machine was not programmable, it was the first to use electronic tubes in an adder.

In 1972, Intel launched the 8008, the first 8-bit microprocessor .< ref > using enhancement load PMOS logic ( demanding 14V, achieving TTL-compatibility by having V < sub > CC </ sub > at + 5V and V < sub > DD </ sub > at-9V )</ ref > It implemented an instruction set designed by Datapoint corporation with programmable CRT terminals in mind, that also proved to be fairly general purpose.

Other technological and engineering feats achieved during, or as a result of, the war include the world's first programmable computers ( Z3, Colossus, and ENIAC ), guided missiles and modern rockets, the Manhattan Project's development of nuclear weapons, operations research and the development of artificial harbours and oil pipelines under the English Channel.
