IBM 3767 Communication Terminal is a serial printer terminal that employed dot matrix print-head technology and, for the first time, the Synchronous Data Link Control (SDLC) communications protocol set under IBM's Systems Network Architecture (SNA). It was introduced in 1974 and was used widely during the late 1970s to 1990s, for attachment to IBM

Needs for more efficient computer terminals

During the late 1960 and 1970s, the computing environment expanded beyond the large computer rooms based on card input/output and started to allow data input and output terminals from remote locations. For such purposes, printer terminals such as the IBM 2741, using the traditional asynchronous serial communication (start-stop signaling), and display terminals such as IBM 2260 and

IBM 3270 The IBM 3270 is a family of block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text ...
