TOSHIBA LAPTOPS
Toshiba was founded by the merging of two companies in 1939.
One, Tanaka Seizosho (Tanaka Engineering Works), was Japan's first manufacturer of telegraph equipment and was established by Hisashige Tanaka in 1875. In 1904, its name was changed to Shibaura Seisakusho (Shibaura Engineering Works). Through the first part of the 20th century, Shibaura Engineering Works became a major manufacturer of heavy electrical machinery as Japan, modernized during the Meiji Era, and became a world industrial power.
The second company, Hakunetsusha, was established in 1890 and was Japan's first producer of incandescent electric lamps. It diversified into the manufacture of other consumer products and in 1899 was renamed Tokyo Denki (Tokyo Electric).
The merger in 1939 of Shibaura Seisakusho and Tokyo Denki created a new company called Tokyo Shibaura Denki. It was soon nicknamed Toshiba, but it wasn't until 1984 that the company was officially renamed Toshiba Corporation.
The group expanded strongly, both by internal growth and by acquisitions, buying heavy engineering and primary industry firms in the 1940s and 1950s and then spinning off subsidiaries in the 1970s and beyond. Groups created include Toshiba EMI (1960), Toshiba Electrical Equipment (1974), Toshiba Chemical (1974), Toshiba Lighting and Technology (1989), Toshiba America Information Systems (1989) and Toshiba Carrier Corporation (1999).
HISTORY OF COMPUTERS - continued (PREV) (PAGE 1)
By 1951 the LEO I computer was operational and ran the world's first regular routine office computer job.
Manchester University's machine became the prototype for the Ferranti Mark I. The first Ferranti Mark I machine was delivered to the University in February, 1951 and at least nine others were sold between 1951 and 1957.
UNIVAC I, the first commercial electronic computer in the United States (third in the world), achieved 1900 operations per second in a smaller and more efficient package than ENIAC.
In June 1951, the UNIVAC I (Universal Automatic Computer) was delivered to the U.S. Census Bureau. Although manufactured by Remington Rand, the machine often was mistakenly referred to as the "IBM UNIVAC". Remington Rand eventually sold 46 machines at more than $1 million each.
UNIVAC was the first 'mass produced' computer; all predecessors had been 'one-off' units. It used 5,200 vacuum tubes and consumed 125 kW of power. It used a mercury delay line capable of storing 1,000 words of 11 decimal digits plus sign (72-bit words) for memory.
Unlike IBM machines it was not equipped with a punch card reader but 1930s style metal magnetic tape input, making it incompatible with some existing commercial data stores. High speed punched paper tape and modern-style magnetic tapes were used for input/output by other computers of the era.
