Description
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). There were 88 graphic characters and so shift characters were used to allow their encoding in six data bits.
