Well, I went digging a bit deeper on the Parallax website, and I found the SX Tech Tool Kit (http://www.parallax.com/detail.asp?product_id=45180). At $229.99 it's a bit more than I wanted to spend. It comes with the SXKey, a dev board, some chips, the "Programming the SX Microcontroller" book, and some other stuff. Not too bad I guess. Anyone have any opinions on the SXKey versus the SXDev? I pretty much plan on programming in assembler, so I don't really care about not being able to use another compiler. How difficult was it to switch from PIC to SX programmingwise? Thanks, Josh -- A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools. -Douglas Adams Robert Ussery wrote: > > Well, I've had good luck with the SXKey.
