IBM 1620 data processing machine with IBM 1627 plotter, on display at the 1962 Seattle World's Fair. The IBM 1620 was a model of scientific minicomputer produced by IBM.It was announced on October 21, 1959, [1] and was then marketed as an inexpensive scientific computer. [2]
But on the Model I indirect addressing was an option, most Model I systems didn't have it. -- RTC 19:57, 17 September 2006 (UTC) [ reply ] Indirect addressing was an optional, extra cost, special feature on the 1620.
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
NGC 1620 is an intermediate spiral galaxy in the constellation of Eridanus. Its velocity with respect to the cosmic microwave background is 3,455 ± 4 km/s, which corresponds to a Hubble distance of 51.0 ± 3.6 Mpc Mpc (∼166 million light-years). [1] It was discovered by German-British astronomer William Herschel on 1 January 1786.
TRADIC. 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.
Hart's first inversor, also known as Hart's W-frame, is based on an antiparallelogram.The addition of fixed points and a driving arm make it a 6-bar linkage. It can be used to convert rotary motion to a perfect straight line by fixing a point on one short link and driving a point on another link in a circular arc.
However, in its original form, the Steinhart–Hart equation is not sufficiently accurate for modern scientific measurements. For interpolation using a small number of measurements, the series expansion with n = 4 {\displaystyle n=4} has been found to be accurate within 1 mK over the calibrated range.
Hart InterCivic Inc. is a privately held United States company that provides election technologies and services to government jurisdictions. Headquartered in Austin, Texas, Hart products are used by hundreds of jurisdictions nationwide, including counties in Texas, the entire states of Hawaii and Oklahoma, half of Washington and Colorado, and certain counties in Michigan [1], Ohio, California ...
