IBM Series/1
The IBM Series/1 is a 16-bit minicomputer, introduced in 1976, that in many respects competed with other minicomputers of the time, such as the PDP-11 from Digital Equipment Corporation and similar offerings from Data General and HP. The Series/1 was typically used to control and operate external electro-mechanical components while also allowing for primitive data storage and handling. Although the Series/1 uses EBCDIC character encoding internally and locally attached EBCDIC terminals, ASCII-based remote terminals and devices could be attached via an I/O card with a RS-232 interface to be more compatible with competing minicomputers.
