IBM 1400 The IBM 1400 series were second-generation (transistor) mid-range business decimal computers that IBM marketed in the early 1960s. The computers were offered to replace tabulating machines like the IBM 407. The 1400-series machines stored infor ...

IBM 7000 The IBM 700/7000 series is a series of large-scale ( mainframe) computer systems that were made by IBM through the 1950s and early 1960s. The series includes several different, incompatible processor architectures. The 700s use vacuum-tube lo ...

System/360 The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applica ...

series. It first became available in 1963 and was used widely during the 1960s. The 1052 Printer-Keyboard was also the basis for the 1052-7 console Printer-Keyboard used on small and medium S/360 processors.

. The 1050 system could include the following devices: * IBM 1051 Central Control Unit * IBM 1052 Printer-Keyboard *

IBM 1053 Console Printer * IBM 1054 Paper Tape Reader * IBM 1055 Paper Tape Punch * IBM 1056 Card Reader * IBM 1057 Card punch * IBM 1058 Printing Card punch * IBM 1092/1093 Programmed Keyboards Communication was done serially, half-duplex, at 75 or 150 bits per second. A modem, such as IBM Line Adapter, was needed for connection to a communication line. The IBM 1050 featured multipoint asynchronous communication (Start Stop protocol), and improved error checking (LRC and VRC), with speed up to 14.8 characters per second (134 baud), compared to the teleprinter's 10 cps. One IBM 1051 and another device were required per subsystem. A set of IBM 1050 Data Communications System is exhibited at the
