The IBM 2741 is a printing computer terminal that was introduced in 1965. [1] Compared to the teletypewriter machines that were commonly used as printing terminals at the time, the 2741 offers 50% higher speed, much higher quality printing, quieter operation, interchangeable type fonts, and both upper and lower case letters.

2021年3月31日 · The IBM 2741 was a Selectric typewriter embedded in a small-desk-size cabinet crammed with electronics and wire bundles, communicating at 134.5 bits per second, half duplex. When it was the computer's turn to transmit, it physically locked the keyboard.

Both the 2740 and 2741 feature a Selectric-based IBM 72 I/O Typewriter using then-end Solid Logic Technology (SLT) circuitry and the ability to be used as a standard typewriter as needed [4] [4]

Type fonts on the IBM 2741 were interchangeable with a type ball: a golf ball shaped device that strikes an ink ribbon on a typewriter to create text. One of these models, donated by the University of Waterloo Institute for Computer Research, is on display in the museum office (DC 1316).

IBM 2741 Communication Terminal This publication describes the application areas, principles of operation, line-control signals, and special features of the IBM 2741 Communication Terminal. The communications facilities and data sets that can …

The IBM 2741 is a printing computer terminal that was introduced in 1965. Compared to the teletypewriter machines that were commonly used as printing terminals at the time, the 2741 offers slightly higher speed, much higher quality printing, quieter operation, interchangeable type fonts, and both upper and lower case letters.

The IBM 2741 was a printing computer terminal introduced in 1965. It combined a ruggedized Selectric typewriter mechanism with IBM SLT electronics and an RS-232-C serial interface. It operated at about 14.1 characters per second with a data rate of 134.5 bits/second (one start bit, six data bits, an odd parity bit, and one and a half stop bits).

The IBM 2741 is a printing computer terminal that was introduced in 1965. Compared to the teletypewriter machines that were commonly used as printing terminals at the time, the 2741 offers 50% higher speed, much higher quality printing, quieter operation, interchangeable type fonts, and both upper and lower case letters.

The IBM 2741 Communications Terminal is a re­ mote input/output terminal providing direct access to a computer such as an IBM System/360 through a multiplexor such as an IBM 2701 Data Adapter Unit, 2702 or 2703 Transmission Control Unit, or an IBM 2712 Remote Multiplexor connected to a 2702 or 2703. Hereafter these units will be referred to

The IBM 2740 and 2741 are IBM's versions of a printer-keyboard designed primarily for point to point communication. The 2740 is the more glorious one with numerous options. The. 2741 is as simple as possible with just one major option. Neither of these units approaches the complexity or number of options available on a 1050 system. | OSTI.GOV
