An Open Letter To Hobbyists
"An Open Letter to Hobbyists" is a 1976 open letter written by Bill Gates, the co-founder of Microsoft, to early personal computer hobbyists, in which Gates expresses dismay at the widespread duplication of software taking place in the hobbyist community, particularly with regard to his company's software. In the letter, Gates expressed frustration with most computer hobbyists who were using his company's Altair BASIC software without having paid for it. He asserted that such widespread use of his software in effect discouraged developers from investing time and money in creating high-quality software. He cited the unfairness of gaining the benefits of software authors' time, effort, and capital without paying them as a rationale for refusing to publish the source code for his company's flagship product, thereby making it unavailable to lower-income hobbyists who could have borrowed such program blueprints from their local library and entered the program into their hobby computer ...

Open Letter
An open letter is a Letter (message), letter that is intended to be read by a wide audience, or a letter intended for an individual, but that is nonetheless widely distributed intentionally. Open letters usually take the form of a letter (message), letter addressed to an individual but are provided to the public through newspapers and other media, such as a letter to the editor or blog. Critical open letters addressed to political leaders are especially common. Two of the most famous and influential open letters are ''J'accuse...!'' by Émile Zola to the president of France, accusing the French government of wrongfully convicting Alfred Dreyfus for alleged espionage; and Martin Luther King Jr.'s 1963 "Letter from Birmingham Jail", including the famous quotation "Injustice anywhere is a threat to justice everywhere". Context In previous centuries, Letter (message), letter writing was a significant form of communication. Letters were normally kept private between the sender and ...

Traf-O-Data
Traf-O-Data was a business partnership between Bill Gates, Paul Allen and Paul Gilbert that existed in the 1970s. The objective was to read the raw data from roadway traffic counters and create reports for traffic engineers. The company had only modest success but the experience was instrumental in the creation of Microsoft Corporation a few years later. Traffic counting State and local governments frequently perform traffic surveys with a pneumatic road tube traffic counter. Rubber hoses are stretched across a road and wheels of passing vehicles create air pulses that are recorded by a roadside counter. In the 1970s the counts were mechanically recorded on a roll of paper tape. The time and number of axles were punched as a 16-bit pattern into the paper tape. (The common Teletype paper tape uses only 7 bits.) Cities would hire private companies to translate the data into reports that traffic engineers could use to adjust traffic lights or improve roads.

Parasitic Engineering
Parasitic Engineering, Inc., was an American computer company founded by Howard Fullmer and Gene Nardi in 1974. Named as a tongue-in-cheek reference to a comment by MITS co-founder Ed Roberts, Parasitic's first products were hardware upgrade kits to MITS' Altair 8800 microcomputer kit, improving the latter's power supply rating and susceptibility to noise. The company later released their own microcomputer based on the same bus as the Altair, the S-100, but it was less popular than the company's hardware-improvement kits. By 1979, the company had pivoted to providing upgrades to Tandy's TRS-80. Parasitic went defunct in 1983. Foundation (1976–1977) Howard Fullmer (born 1947) and Gene Nardi (born 1948) founded Parasitic Engineering in 1974. The two business partners had met at the University of California, Berkeley, where they both worked in the university's department of psychology as computer consultants. The company was originally based out of the basement of Fullmer's O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Processor Technology
Processor Technology Corporation was a personal computer company founded in April 1975, by Gary Ingram and Bob Marsh in Berkeley, California. Their first product was a 4K byte RAM board that was compatible with the MITS Altair 8800 computer but more reliable than the MITS board. This was followed by a series of memory and I/O boards including a video display module. A Processor Technology advertisement showing a motherboard with eight add-in boards. '' Popular Electronics'' magazine wanted a feature article on an intelligent computer terminal and Technical Editor Les Solomon asked Marsh and Lee Felsenstein to design one. It was featured on the July 1976, cover and became the Sol-20 Personal Computer. The first units were shipped in December 1976 and the Sol-20 was a very successful product. The company failed to develop next generation products and ceased operations in May 1979.Freiberger (2000), 153-155 History Bob Marsh, Lee Felsenstein and Gordon French started design ...

It was developed from and was subsequently used alongside punched cards, the difference being that the tape is continuous. Punched cards, and chains of punched cards, were used for control of looms in the 18th century. Use for telegraphy systems started in 1842. Punched tapes were used throughout the 19th and for much of the 20th centuries for programmable looms, teleprinter communication, for input to computers of the 1950s and 1960s, and later as a storage medium for minicomputers and Numerical control, CNC machine tools. During the Second World War, high-speed punched tape systems using opti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altair BASIC Paper Tape
Altair is the brightest star in the constellation of Aquila and the twelfth-brightest star in the night sky. It has the Bayer designation Alpha Aquilae, which is Latinised from α Aquilae and abbreviated Alpha Aql or α Aql. Altair is an A-type main-sequence star with an apparent visual magnitude of 0.77 and is one of the vertices of the Summer Triangle asterism; the other two vertices are marked by Deneb and Vega. It is located at a distance of from the Sun. Altair is currently in the G-cloud—a nearby interstellar cloud formed from an accumulation of gas and dust. Altair rotates rapidly, with a velocity at the equator of approximately 286 km/s.From values of ''v'' sin ''i'' and ''i'' in the second column of Table 1, Monnier et al. 2007. This is a significant fraction of the star's estimated breakup speed of 400 km/s. A study with the Palomar Testbed Interferometer revealed that Altair is not spherical, but is flattened at the pole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fred Moore (activist)
Fred Moore (1941–1997) was an American political activist who was central to the early history of the personal computer.

The Fool On The Hill
"The Fool on the Hill" is a song by the English rock band the Beatles from their 1967 EP and album '' Magical Mystery Tour''. It was written and sung by Paul McCartney and credited to the Lennon–McCartney partnership. The lyrics describe a solitary figure, the one named in the title, who is not understood by others, but is actually wise. McCartney said the idea for the song was inspired by the Dutch design collective the Fool, who derived their name from the tarot card of the same name, and possibly by Maharishi Mahesh Yogi. The song's segment in the '' Magical Mystery Tour'' television film was shot separately from the rest of the film and without the other Beatles' knowledge. Accompanied by a professional cameraman, McCartney filmed the scene near Nice in France. In 1968, Sérgio Mendes & Brasil '66 recorded a cover version of the song that reached the top ten in the US. By the late 1970s, "The Fool on the Hill" was one of McCartney's most widely recorded ballads. A sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
