Probably showing my age but RTL and CMOS cookbooks were pretty good for reference. I'd also consider something like "Electronic Workbench" software so you can virtually build almost anything and see what it does before you buy one part or heat up the iron. There was a shareware program out a while ago that let you drag a pic and other parts onto a virtual breadboard then run and load your program and see the results, like mplab but much more basic. They did a "upgrade" and ruined it but I'd think there were others that would get you playing quick. Unless RatShack is your only option, try and find a wholesaler or distributor or retail store that has the parts. It will be a lot cheaper. Or learn how to desolder and go to garage sales ;-] Dave -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
