Datapoint Corporation, originally known as Computer Terminal Corporation (CTC), was a computer company based in San Antonio, Texas, United States.Founded in July 1968 by Phil Ray and Gus Roche, its first products were, as the company's initial name suggests, computer terminals intended to replace Teletype machines connected to time sharing systems.
The communication system offers a reduced instruction set to read and write datapoint values. Datapoints have to conform to standardised datapoint types, themselves grouped into functional blocks. These functional blocks and datapoint types are related to applications fields, but some of them are of general use (such as date and time).
An E-8 crew member entering data using an AN/PYQ-10 before a flight. The AN/PYQ-10 Simple Key Loader (SKL) is a ruggedized, portable, hand-held fill device, for securely receiving, storing, and transferring data between compatible cryptographic and communications equipment.
The token-passing bus protocol of that I/O device-sharing network was subsequently applied to allowing processing nodes to communicate with each other for file-serving and computing scalability purposes. An application could be developed in DATABUS, Datapoint's proprietary COBOL-like language, and deployed on a single computer with dumb ...
A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. As well as the stream of bits from a file stored as a single unit in a file system, some may also send relevant metadata such as the filename, file size and timestamp – and even file-system permissions and file attributes. Some examples:
The DataPoint 3300 was the first computer terminal manufactured by Computer Terminal Corporation, later renamed Datapoint, announced in 1967 [1] and shipping in 1969. [2] Since this terminal was intended to replace a teleprinter such as those made by Teletype Corporation it was one of the first glass TTYs (glass for the screen, TTY as the abbreviation for "Teletype") ever produced.
Inforex Inc. corporation manufactured and sold key-to-disk data entry systems in the 1970s and mid-1980s. The company was founded by ex-IBM engineers to develop direct data entry systems that allowed information to be entered on terminals and stored directly on disk drives, replacing keypunch machines using punched cards or paper tape, which had been the dominant tools for data entry since the ...
Data Disc was founded in February 1962 in Palo Alto, California by Armin Miller and Daniel Teichroew. [1] [2] Miller had previously worked for the Ampex Corporation, where he developed the basis for modified frequency modulation (MFM), a line code for magnetic data recording that doubled the density and transfer rate of data of the earlier FM encoding scheme.
