6	Reader I/O Letters to the Editor
8 Harv Weiner	New Product News
12 Don Newquist	A/D Conversion with Zilog's Z8 Microcontroller Often applications using A/D conversion compromise accuracy, speed, or cost. Don offers four ADC configurations. He shows you how to use specific techniques to your advantage. His goal: little compromise! Download: Z8ADC.ZIP
22 David Gaddis	Battery Load/Charge Analyzer Here's the circuitry and software of a universal, portable test instrument to evaluate battery charge/discharge. It transforms tedious time-based measurements into simple, automated operations. Download: BCDA.EXE
30 David Prutchi	Sniffing EMI in the Near Field Noncompliance with FCC and EMC regulations affects everyone! So, David shows designers how to construct probes that identify and isolate sources of EMI that inevitably make it into a circuit.
42 Ingo Cyliax	Easy-to-Use Serial EEPROMs There seem to be as many flavors of serial EEPROMs as there are manufacturers. Interfaces using 2, 3, and 4 wires abound. Now, Atmel has introduced a family of EEPROMs that does it all. Download: EEPRG.ZIP
52 Ed Nisley	Firmware Furnace 80x86 Performance: I/O Bound The next time you're starting the design of an embedded PC product, don't put a lot of weight on processor speed until you look at what it will spend its time doing. Ed explains why. Download: FF71.ZIP
60 Jeff Bachiochi	From the Bench Printer Sharing: Automatic Parallel Printer Switch Stow your assembler, compiler, and programmer. This month's project doesn't need a micro. Jeff creates a smart printer switch that shares your favorite printing device between two computers.
Embedded PC 64 Harv Weiner	Nouveau PC
Embedded PC 70 Scott Baisch Kevin Smith	WinLight Part 1: The Nonfat Operating System For many embedded developers, Windows has brought more problems than solutions. WinLight, however, targets the embedded market. It provides a leaner, meaner, fully GUI, protected-mode, Windows-like operating system.
Embedded PC 74 Brad Reed	Rolling Your Own Intel '386EX-based Embedded PC Brad introduces the R300EX and R380EX memory and bus controllers created by RadiSys to support Intel's '386EX. A highly-practical sidebar gives design advice for integrating the R300EX and R380EX with PC/104.
Embedded PC 82 David Chanoux	Embedded PCs Embedded Systems for Weight and Force Measurement Applications Until recently, there has been no tool to integrate weighing sensors with embedded PCs. David lets us in on some recent improvements in the link between the PC/104 standard and load-cell technology.
Embedded PC 89 Fred Eady	Driving Multiaxis Stepper Motors Fred ushers us up to motion-control heaven without generating a single line of code. He's quick to show how easy it is to design and implement even the most demanding motion-control application with off-the-shelf stepper equipment.
98 Tom Cantrell	Silicon Update The Little LAN That Could Is Tom's secret decoder ring a sign he's moving into the spy business? Not likely once he's let the cat out of the bag (or the time out of the can) about Dallas Semiconductor's line of touch products.

106 Ken Davidson	ConnecTime -- Excerpts from the Circuit Cellar BBS
120 Steve Ciarcia	Priority Interrupt 'Bots Got No Respect
