IBM 3101

The IBM 3101 ASCII Display Station, and IBM's subsequent products, the 3151/315X and 3161/316X, were display terminals with asynchronous serial communication (start-stop signaling) that were used with a variety of IBM and non-IBM computers during the 1980s–90s, especially the data processing terminals on non-IBM minicomputers, IBM Series/1 and IBM AIX computers.

The IBM 3101 ASCII Display Station appeared in 1979. It featured:

Unusually for IBM's practices at the time, it also:

The IBM 3101 was used with a variety of IBM and non-IBM computers. As an asynchronous communication display, it competed with products from Digital Equipment Corporation (e.g. VT100), Wyse Technology (e.g. 50/60/70), Applied Digital Data Systems (e.g. ADDS Viewpoint) and others. It was often used as a data processing terminal on non-IBM minicomputers and the IBM Series/1.

The IBM 3102 dot-matrix printer used thermal-paper print technology, and could be attached to the IBM 3101's auxiliary port. It supported 80 5x7 dot-matrix characters per line, 6 lines per inch, and output 40 characters per second.

The IBM 3161/3163 ASCII Display Stations became available in 1985 and featured:

The IBM 3164 Color ASCII Display Station, available in 1986, featured a 14-inch green, amber or white monochrome CRT display.

The IBM 3151 ASCII Display Station became available in 1987, and included:

In 1988, the 3151 garnered IBM's Japan subsidiary a Good Design Product Award from the Japan Institute of Design Promotion.

The IBM 3152 Color ASCII Display Station became available in 1992 in European, Middle Eastern and African countries. It included:

The IBM 3153 InfoWindow II Color ASCII Display Station became available in 1993. Similarly to the NCR (Boundless Technologies) 2900 series of terminals, it could be used with cash registers and kitchen monitor systems.
