Mailüfterl
Mailüfterl is a nickname for the Austrian ''Binär dezimaler Volltransistor-Rechenautomat'' (binary-decimal fully transistorized computing automaton), an early transistorized computer. Other early transistorized computers included TRADIC, Harwell CADET and TX-0. Mailüfterl was built from May 1956 to May 1958 at the Vienna University of Technology by Heinz Zemanek. Heinz Zemanek had come to an agreement with Konrad Zuse, whose company Zuse KG would finance the work of Rudolf Bodo, who helped build the Mailüfterl, also that all circuit diagrams of the Z22 were supplied to Bodo and Zemanek, and that after the Mailüfterl project Bodo should work for the Zuse KG to help build the transistorized Z23. The first program, computation of the prime 5,073,548,261, was executed in May 1958. Completion of the software continued until 1961. The nickname was coined by Zemanek: ''Even if it cannot match the rapid calculation speed of American models called "Whirlwind" or "Typhoon", it ...

Heinz Zemanek
Heinz Zemanek (actually ''Heinrich Josef Zemanek'') (1 January 1920 – 16 July 2014) was an Austrian computer pioneer who led the development, from 1954 to 1958, of one of the first complete transistorised computers on the European continent. The computer was nicknamed Mailüfterl — Viennese for "May breeze" — in reference to Whirlwind, a computer developed at MIT between 1945 and 1951. Life Heinz Zemanek went to a secondary school in Vienna and earned his Matura in 1937. He then started to study at the University of Vienna. In 1940, Zemanek was drafted into the Wehrmacht, where he served in a "communication unit" and also as a teacher in an Intelligence Service School. Returning to studying radar technology he earned his Diplom in 1944 with the help of University of Stuttgart professor Richard Feldtkeller (1901–1981). After the war Zemanek worked as an assistant at the university and earned his PhD in 1951 about timesharing methods in multiplex telegraphy. In 1952 he c ...

List Of Transistorized Computers
This is a list of transistorized computers, which were digital computers that used discrete transistors as their primary logic elements. Discrete transistors were a feature of logic design for computers from about 1960, when reliable transistors became economically available, until monolithic integrated circuits displaced them in the 1970s. The list is organized by operational date or delivery year to customers. Computers announced, but never completed, are not included. Some very early "transistor" computers may still have included vacuum tubes in the power supply or for auxiliary functions. 1950s 1953 *University of Manchester Transistor Computer 1953 (prototype) 1955 (full scale) experimental 1954 *Bell Labs TRADIC for U.S. Air Force 1955 * Harwell CADET demonstrated February 1955, one-off scientific computer 1956 *Electrotechnical Laboratory ETL Mark III (Japan) experimental, began development 1954, completed 1956, Japan's first transistorized stored-program computer * M ...

TRADIC
The TRADIC (for TRAnsistor DIgital Computer or TRansistorized Airborne DIgital Computer) was the first transistorized computer in the USA, completed in 1954. The computer was built by Jean Howard Felker of Bell Labs for the United States Air Force while L.C. Brown ("Charlie Brown") was a lead engineer on the project, which started in 1951. The project initially examined the feasibility of constructing a transistorized airborne digital computer. A second application was a transistorized digital computer to be used in a Navy track-while-scan shipboard radar system. Several models were completed: TRADIC Phase One computer, Flyable TRADIC, Leprechaun (using germanium alloy junction transistors in 1956) and XMH-3 TRADIC. TRADIC Phase One was developed to explore the feasibility, in the laboratory, of using transistors in a digital computer that could be used to solve aircraft bombing and navigation problems. Flyable TRADIC was used to establish the feasibility of using an airborne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Z22 (computer)
The Z22 was the seventh computer model Konrad Zuse developed (the first six being the Z1, Z2, Z3, Z4, Z5 and Z11, respectively). One of the early commercial computers, the Z22's design was finished about 1955. The major version jump from Z11 to Z22 was due to the use of vacuum tubes, as opposed to the electromechanical systems used in earlier models. The first machines built were shipped to Berlin and Aachen. By the end of 1958 the ZMMD-group had built a working ALGOL 58 compiler for the Z22 computer. ZMMD was an abbreviation for Zürich (where Rutishauser worked), München (workplace of Bauer and Samelson), Mainz (location of the Z22 computer), Darmstadt (workplace of Bottenbruch). In 1961, the Z22 was followed by a logically very similar transistorized version, the Z23. Already in 1954, Zuse had come to an agreement with Heinz Zemanek that his Zuse KG would finance the work of Rudolf Bodo, who helped Zemanek build the early European transistorized computer Mailüft ...

Philips
Koninklijke Philips N.V. (), commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, it has been mostly headquartered in Amsterdam, though the Benelux headquarters is still in Eindhoven. Philips was formerly one of the largest electronics companies in the world, but is currently focused on the area of health technology, having divested its other divisions. The company was founded in 1891 by Gerard Philips and his father Frederik, with their first products being light bulbs. It currently employs around 80,000 people across 100 countries. The company gained its royal honorary title (hence the ''Koninklijke'') in 1998 and dropped the "Electronics" in its name in 2013, due to its refocusing from consumer electronics to healthcare technology. Philips is organized into three main divisions: Personal Health (formerly Philips Consumer Electronics and Philips Domestic Appliances and Personal Care), Connecte ...

In Kind
The term in kind (or in-kind) generally refers to goods, services, and transactions not involving money or not measured in monetary terms. It is a part of many spheres, mainly economics, finance, but also politics, work career, food, health and others. There are many different types of in kind actions throughout the mentioned branches, which can be identified and distinguished. In-kind contributions An in-kind contribution is a non-cash contribution of goods or a service. Those are either offered free or at less than usual charge for them. Similarly, when a person or entity pays for services on the committee’s behalf, the payment is also considered as an in-kind contribution. In-kind services and contributions are valued at their fair market value or at their actual cost. In other words, they are valued at what you would pay for them if they were not donated. There are two types of receivers of in-kind contributions: individuals and companies. For individuals, the provider of in- ...

Transistor
upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electrical power, power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually cons ...
