The ADDS Viewpoint was a low-cost asynchronous CRT display terminal introduced in June 1981. The terminal was introduced at a list price of $650 and was offered in two models, designated A and B. [1] [2][3]

The Model B differed from the Model A primarily through the addition of a glare filter intended to reduce reflections on the display screen in brightly lit office environments.[2]

The ADDS Viewpoint was marketed as an economical business terminal suitable for data entry, interactive computing, and general-purpose time-sharing applications. It was introduced during a period when demand for inexpensive raster display terminals was increasing rapidly due to the spread of minicomputers and multiuser microcomputer systems. [1]

Design and features

The ADDS Viewpoint was a raster-scan CRT terminal with an integrated keyboard and a self-contained desktop enclosure. Terminals of this class typically combined the display electronics, power supply, and monitor in a single unit intended for office use.

Asynchronous serial communication was standard for terminals of this type, allowing connection to host computers through RS-232 or 20 mA current loop interfaces. Such terminals were commonly used with minicomputer systems and time-sharing services where a video display terminal replaced earlier printing teletypes.

Advertising for the ADDS Viewpoint emphasized affordability and compatibility with existing computer systems, positioning the terminal as a practical replacement for earlier and more expensive display terminals.[2]

Market context

During the early 1980s the market for video display terminals became highly competitive as semiconductor integration reduced the cost of display controllers and terminal logic. Manufacturers introduced numerous low-cost models intended for office automation, data entry, and distributed computing environments.

The relatively low introductory price of the ADDS Viewpoint reflected this industry trend toward inexpensive desktop terminals. Advertisements for the product continued to appear several years after its introduction, indicating that the model remained available into the mid-1980s. [4]
