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.
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.
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.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exis
System devices and components (e.g. line couplers, backbone couplers). Classifying devices as either "sensor" or "actuator" is outdated and simplistic. Many actuators include controller functionality, but also sensor functionality (for instance measuring operating hours, number of switch cycles, current, electrical power consumption, and more).
IN and OUT tokens contain a seven-bit device number and four-bit function number (for multifunction devices) and command the device to transmit DATAx packets, or receive the following DATAx packets, respectively. IN token expects a response from a device. The response may be a NAK or STALL response or a DATAx frame. In the latter case, the host ...
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 ...
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 ...
