Monte Dalrymple

Updating a Classic: the Z80380 Microprocessor

After reviewing the Z80's popularity, Monte introduces the Z380, a new chip offering a full complement of 16-bit data manipulations and enough 32-bit instructions to handle the new 32-bit addresses.


Richard Newman

Connect the Personal PBX to the Real World

Richard presents a circuit that connects the Personal PBX small switch with the "outside" world -- the telephone company central office. A SLIC interface used in conjunction with the PBX enhances conversation quality.

LPT: Analog!

A 12-bit A/D Converter Printer Port Adapter

Are you having problems getting collected data from instruments into your computer without a fancy interface? If so, LPT: Analog! may help. It interfaces analog-output instruments and most PCs.



Ron Cates

PIC17C44 High-End Microcontroller Architectural Overview

Here's an MCU that provides increased performance and an improved migration path. Discussion focuses on the instruction set, register file, bus structure, and variable word-length instructions.

R. E. Billings

High-Speed Network Technology

Traffic jams used to happen only on the way to and from work. However, with the vast increase in network traffic, data congestion is becoming a problem at work also. Billings offers a fix with new high-speed networking.

Ed Nisley

Unscrewing the Inscrutable

With off-the-shelf components, tweaking becomes the norm for engineers. Here, Ed presents some references and sources he's used while writing decidedly nonstandard 80x86 programs and building oddball hardware.

PC/104 Quarter

Chassis and Enclosures: A PC/104 Packaging Overview

Different problems need different solutions. This is especially true in packaging where real estate, power, temperature, shock, and so on can have a dramatic effect. Dave and Paul give an overview of what is out there in PC/104 design.

Small Displays for Embedded Systems

This month, Russ points out smaller display options available to the embedded system architect. He gets into the nitty-gritty of how designers interface these small, non-PC-compatible units to their embedded PC designs.

Firmware Furnace

Vid-Link Characters: Part 2: Bits to Dots

After last month's discussion of the Vid-Link hardware, Ed sets out to squeeze the necessary firmware into an impossibly small space. Find out what tricks he has to pull to do it.



Jeff Bachiochi

From the Bench

Intel Hex to BASIC Data Statement Translator

Are you an 8052 user trying to mix assembly language and BASIC? If so, Jeff has a solution. He presents a translation file which automatically creates a BASIC data statement file from an Intel hex file.

Silicon Update

Fuzzy Buster

Fuzzy logic is no longer quite so alien. As Tom shows in this article, fuzzy logic has hit hardware. The AL220 fuzzy controller offers simple, small, and cheap solutions for management of analog input and output.
