Why do people fixate like this on THE ONE SOLUTION, when they have competent people advising them that their solution is unworkable? I've seen this before when someone, usually from marketing, comes in and tells us "we need this". It's usually some way off the wall requirement, and they WILL NOT let go of it despite small objections like that it might defy the laws of physics, or some other niggling little engineering thing. "We need 16 bit technology!" The product was moving packets of a couple hundred bytes over a 212A modem.. The host was 7E1 and that wouldn't ever change. "We need 1M of SRAM in this <$100 product". At the time, 1M of SRAM cost about $400 just in chips on the table. It also was VASTLY more than was ever needed by the end users. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
