Article Abstract:
Word processors and memory typewriters along with microcomputers are leading the charge of microprocessors in office automation. Law, accounting, banking, and investment offices are using word processing systems for lower costs, time saving, and improved text quality. To consolidate peripherals and processors, shared-resource and shared-logic systems are used. One of the most popular schemes today is the cluster system, which combines shared-resource and and shared-logic systems. These systems crash less thanks to error- checking software and redundant hardware. Personal computers have made computers available to people who otherwise would not have used one. Local area network (LANS) or micronets have linked these computers. Other technologies appearing in offices include professional workstations, virtual memory, and multiterminal business systems. Block diagrams illustrate a microprocessor-based office system and a multiterminal system. Also illustrated are a list of business microcomputers and screen displays from typical workstation software.

Math chips: how they work
Article Abstract:
Math coprocessors speed up mathematical computations and give system designers performance, cost, and integration options. The Intel 80387 works in tandem with the company's 80386 chip, but other coprocessors are accessory boards rather than chips. The need for such aids is evident by the increasingly complex mathematical applications that are being developed for microcomputers as well as for workstations. Graphics processing requires huge chunks of mathematical computations to represent, store, and draw images to a screen, for instance, and graphics are now in high demand. Coprocessors are the most convenient and least expensive way to increase math performance for small computers. Data is provided for most math coprocessors and the microprocessors they work with.

'Dumb' Phones Use Smart Chips
Article Abstract:
A new AT&T phone system uses a Western Electric 8-bit microprocessor to route calls from office telephones, to the central telephone office, to the larger telephone network. The telephones have integrated circuits to send digital signals, but only the central station has a microprocessor. Cartridges containing read-only memory can be plugged into the central station for system expansion. A diagram of the new AT&T phone system is included.
