14 Ron Stence	Speed up Your M68040 with an Interleaved Bursting EPROM Interface Looking to improve the performance of your latest MC68040 or MC68060 design without locking yourself into a sole source of specialized memory devices? Explore one alternative that uses standard EPROMs.
26 Del Hatch	Designing with FPGAs Part 1: An Overview It started with the transistor, then led to SSI, MSI, LSI, VLSI, PALs, and now Field-programmable Gate Arrays. There is a whole range of FPGAs available on the market. How do you pick which one to use?
36 Brad Hunting	Loader31: A Pseudo EPROM Emulator Tired of having to spend $$ to develop embedded firmware by means of EPROM burning or emulation? Look no further because Loader31 provides the same solution, only at a lower cost. Download: LOADER31.ZIP LDR31TST.ZIP
42 Ed Nisley	Firmware Furnace Booting C: Writing a Micro-C BIOS Extension for the '386SX Project After much cajoling on the BBS, Ed has finally relented and agreed to show how to write a BIOS extension using Micro C. It isn't as hard and doesn't use as much memory as you might think. Download: FF40.ZIP
56 Jeff Bachiochi	From the Bench Talk on the Phone Without a Word We've all heard of people who can't walk and talk at the same time. Jeff shows you how to let your fingers do the talking while letting them do the walking. It works even if you are tone deaf... Download: FTB40.ZIP
62 Tom Cantrell	Silicon Update The Swiss Army Sends in the Special Forces Moving on to bigger and better chips, Tom takes a look at WSI's heavyweights in the PLD arena. The PSD4xx and PSD5xx pack a lot of punch for the money.
68 John Dybowski	Embedded Techniques Decoding Magnetics With the growing proliferation of credit cards with magnetic stripes, it only makes sense that you might want to use one with your next project. It turns out most stripes are encoded in much the same way, and reading them isn't hard.
78 Russ Reiss	Patent Talk
81	Advertiser's Index
84 Ken Davidson	ConnecTime -- Excerpts from the Circuit Cellar BBS
96 Steve Ciarcia	Steve's Own INK Lest We Forget that Chips Can ... and Will
