New screens from IBM
IBM has announced two new models in its 3270 series of display stations: a compact, low-cost model, and one that uses a state-of-the-art, gas-panel display. The low-cost display station, the IBM 3178, is a compact, light-weight terminal that incorporates the most popular functions of the IBM 3278 Model 2 at lower prices. Its 30.5 cm screen can be tilted and swivelled, and the slope of the keyboard adjusted for operator comfort. It can easily fit on an office desk. The IBM 3290 gas-panel display station is designed primarily for program development, report retrieval, and data base-data communications applications.
It can display up to 9920 alphanumeric characters and a wide range of graphics, such as line drawings, charts and sketches. The large (27cm by 34cm) flat screen can be divided into quadrants to provide an operator with access to as many as four applications or data bases in one or more computers. The screen is a sealed sandwich of two glass plates less than 0.35 mm apart. The space between the plates is filled with neon/argon gas which glows as electrical charges are selectively applied on to 737,280 intersections of a wire grid to create high-resolution orange-on-black images. With the two new terminals IBM has announced:
• The IBM 3270 personal computer attachment, which allows users to integrate IBM Personal Computers into their 3270 communications network as intelligent workstations. • An enhanced IBM 3274 control unit, offered in four models to direct data transmission within a communications network. • The IBM 3299 terminal multiplexer, which can con-
nect up to eight terminals to the 3274 control unit through a single main cable, instead of eight separate ones, resulting in lower installation costs. 9 The IBM 3725 communication controller, with performance typically double that of the IBM 3705II controller and which can significantly improve the performance of data processing networks.
