FACOM 100
The FACOM 100 was an early electromechanical computer built by Fujitsu in 1954 which used binary-coded decimal arithmetic. The design of the later FACOM 128 was influenced by experience gained from building the FACOM 100.

Electromechanical Computer
A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment output displays. More complex examples could carry out multiplication and division—Friden used a moving head which paused at each column—and even differential analysis. One model, the Ascota 170 accounting machine sold in the 1960s, calculated square roots. Mechanical computers reached their zenith during World War II, when they formed the basis of complex bombsights including the Norden, as well as the similar devices for ship computations such as the US Torpedo Data Computer or British Admiralty Fire Control Table. Noteworthy are mechanical flight instruments for early spacecraft, which provided their computed output not in the form of digits, but through the displacements of indicator surfaces.

Binary-coded Decimal
In computing and electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.g. error or overflow). In byte-oriented systems (i.e. most modern computers), the term ''unpacked'' BCD usually implies a full byte for each digit (often including a sign), whereas ''packed'' BCD typically encodes two digits within a single byte by taking advantage of the fact that four bits are enough to represent the range 0 to 9. The precise four-bit encoding, however, may vary for technical reasons (e.g. Excess-3). The ten states representing a BCD digit are sometimes called '' tetrades'' (the nibble typically needed to hold them is also known as a tetrade) while the unused, don't care-states are named ''pseudo-tetrad(e)s'', ''pseudo-decimals'', or ''pseudo-decimal digits''. BCD's main virtue, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FACOM 128
The FACOM 128 was a relay-based electromechanical computer built by Fujitsu. Two models were made, namely the FACOM 128A, built in 1956, and the FACOM 128B, built in 1959. , a fully working FACOM 128B is still in working order, maintained by Fujitsu staff at a facility in Numazu in Shizuoka Prefecture. The FACOM 128B processes numbers using a bi-quinary coded decimal representation.

FACOM
Stanley Black & Decker, Inc., formerly known as The Stanley Works, is a ''Fortune'' 500 American manufacturer of industrial tools and household hardware, and a provider of security products. Headquartered in the Greater Hartford city of New Britain, Connecticut, Stanley Black & Decker is the result of the merger of The Stanley Works and Black & Decker on March 12, 2010. History The Stanley Works came to existence as a direct result of the 1920 merger of Stanley's Bolt Manufactory, founded by Frederick Trent Stanley in 1843, and the Stanley Rule and Level Company, Enormously detailed model history of planes manufactured by Stanley. founded by Frederick's cousin, Henry Stanley, in 1857. DeWalt was acquired in 1960, and sold to Black & Decker. In March 12, 2010 Black & Decker merged with Stanley Works to become Stanley Black & Decker. It’s a wholly owned subsidiary of that company. During World War II, Stanley Works received the Army-Navy "E" Award for excellence in war pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-mechanical Computers
Electromechanics combine processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focus on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other. This process is especially prominent in systems such as those of DC or AC rotating electrical machines which can be designed and operated to generate power from a mechanical process (Electric generator, generator) or used to power a mechanical effect (Electric motor, motor). Electrical engineering in this context also encompasses electronic engineering, electronics engineering. Electromechanical devices are ones which have both electrical and mechanical processes. Strictly speaking, a manually operated switch is an electromechanical component due to the mechanical movement causing an electrical output. Though this is true, the term is usually understood to refer to devices which involve an electrical signal to create mechanical mov ...
