In the 'Elmer 160" lesson at http://amqrp.org/elmer160/lessons/E160L04.pdf , on page 6 it says "At this point, you may find it useful to find the file for the quick reference card, and print out the page titled '14-Bit Core Instruction Set'." Does anyone know what this is referring to? Thanks! - Mark Bellamy -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
