In This Issue

Innovations in microprocessor and support chips are closing the gap between the speed and power of minicomputers and that of micros. As Robert Tinney's cover illustrates, the scales are tipped in favor of the l6-bit chips. "The National Semiconductor NS16000 Microprocessor Family" by Glenn Leedy introduces you to the NS16032 processor and its related chips. "Design Philosophy Behind Motorola's MC68000" by Thomas W. Starnes begins a multi-part study of the heart of machines such as the Lisa and the Radio Shack Model 16. In "Intel's 80186." Tony Zingale describes this new chip that combines the functions of the 8086 and several support chips in one device. "The CRT 9007 Video Processor and Controller" by Brian Cayton and Mort Herman discusses a sophisticated chip that greatly simplifies the design of smart terminals. Steve Levine looks at "Super Graphics Hardware from NEC." "The Intel 8087 Numerics Processor Extension" by R. B. Simington describes the theory and use of this coprocessor chip to speed up numeric computations on 8086/8088-based computers. In the first BYTE West Coast report, Phil Lemmons brings us news of the way in which software houses are responding to the new advances in hardware. Steve Ciarcia tells you how to "Build an RS-232C Breakout Box." Plus our regular features.
