	HIGH-TEMPERATURE ELECTRONIC DESIGN
		Part 2: Reducing the Risk by George Novacek When you think of high-temperature operation, do you think of melted solder and disintegrated insulation? Sometimes operating in a harsh environment is the only choice. An elevated temperature usually elevates risk, but this month George offers some options. High-temperature technology has not been fully explored, but some applications can benefit your cause, and you don't have to be a semiconductor manufacturer to make it work. February 2001
	EMBEDDED MULTITASKING
		The Easy Way by Charles Kosina With memories of the old PS/2, Charles, a hardware guy, takes on the software task of multitasking. He likes to keep things simple and prefers the overall benefits of assembler language. His top-down state machine approach makes for more structured writing and easier debugging. The technique works mainly with Z180 and 8051 class processors, but you can also try it with your own favorite micro. February 2001
	AN S7600A/PIC16F877 JOURNEY
		Part 2: Revving it Up by Fred Eady Continuing on his journey, Fred forges a path all the way through to using the S-7800A/PIC16F877 Internet Engine as a web server. With an everyday PIC, a C compiler, a tiny firmware protocol stack, and some common components, he shows us how to put them on the Internet. As Fred says, "(There's) light at the end of the Internet tunnel!" February 2001
	PIC A COMPACTFLASH CARD
		by Mark Samuels New tech toys are always exciting to any gadget junkie, and Mark's no exception. Talk about a cool little device, the CompactFlash card has countless possibilities. If you're looking to create a digital picture frame or an MP3 player, for example, the CF card can do it. With the wonder of removable memory, you can expect to see this format around for some time. February 2001
	LINUX LESSONS
		by George Martin Practically buying up the store at an outlet hot spot, George only had to shell out $4.99 each for vintage versions of Linux. Averting the $70 price tag for the updated version, he felt more at ease to experiment. Linux, which is virtually free and open-sourced, is only getting better. To utilize the multitasking nature of Linux, take a tip from George and take advantage of the closeouts! February 2001
	SOFT CELL
		by Tom Cantrell It's the promise of tomorrow. Field-programmable System-on-Chip technology holds potential for the future, and one middle-of-the-road soft core CPU is helping to pave the way. Microlor Systems' ProMic comes with a tool suite of the most popular peripherals, a five-stage pipeline to deliver double-digit clock rates, and portability to perform across a variety of FPGAs. Time-consuming negotiations are a thing of the past with ProMic's simple retail pricing model. The silicon penalty is a tradeoff for the greater gain. February 2001
