I see there is an article in Radio Electronics magazine in the classified section selling information to 'construct and program smart cards w/pic 16C84'. I've always been intigued by this and would like information, and not for the dubious nature, but for the intellectual challenge. I built a ROM copier for the ATARI(dating myself), and for the SNES, never used them, just wanted to see how it was done. Also if anyone has any information on MP2/3 decoding with the PIC, would you please pass it my way. I'd like to build some portable thingy to play em. Perhaps just small snippets of audio, played from static or dynamic ram. Put it in your grandma's pillow sort of thing....... Thanks, Craig craiglee@telusplanet.net
