Among these was the use of liquid nitrogen for cooling the CMOS-based CPUs. The ETA10 successfully met the company's initial goals (10 GFLOPS), with some models achieving a cycle time of about 7 ns (143 MHz) - considered rapid by mid-1980s standards. They delivered seven liquid nitrogen-cooled versions and 27 smaller, air-cooled versions.
Physicists led by Rainer Blatt join forces with scientists at the Massachusetts Institute of Technology (MIT), led by Isaac Chuang, to efficiently implement Shor's algorithm in an ion-trap-based quantum computer. [219] IBM releases the Quantum Experience, an online interface to their superconducting systems.
The main reason for the ETA-10's speed was the use of liquid nitrogen (LN 2) cooling in some models to cool the CPUs. Even though it was based on then-current CMOS technologies, the low temperature allowed the CPUs to operate with a ~7 ns cycle time, so a fully loaded ETA-10 was capable of about 9.1 GFLOPS. The design goal had been 10 GFLOPS ...
Apple II computer introduced based on an 8-bit MOS Technology 6502 microprocessor running at 1 MHz with 4 KB of RAM. It had an open architecture, used color graphics, and an audio cassette interface for loading programs and storing data. Later, in July 1978, a floppy disk drive was made available with an elegantly designed interface.
Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire. To prevent corrosion, nitrogen generators are used in place of or in conjunction with a compressed air system to provide supervisory nitrogen gas in place of air for dry pipe and pre-action fire sprinkler systems.
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
The trackball was invented as part of a radar plotting system named Comprehensive Display System (CDS) by Ralph Benjamin when working for the British Royal Navy Scientific Service. [ 69 ] [ 70 ] Benjamin's project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user ...
Invention of the Micral N, the earliest commercial, non-kit personal computer based on a microprocessor. 1967 Thompson, Ken: Created the Unix operating system, the B programming language, Plan 9 operating system, the first machine to achieve a Master rating in chess, and the UTF-8 encoding at Bell Labs and the Go programming language at Google ...
