Anyway it depends on your definition of "any". I did some fooling with GPIB a LONG time ago (remember the Osborne computer?) I have a dim memory of bit banging but also a magic controller chip of some sort. I suspect I got the protocol by reading the sheets on the chip and then implemented the bit-bang. I do have a recollection of chainging the direction of signal lines, and "talkers" and "listeners". It was to make a 9-track tape drive work. It WAS entertaining. So if I see a question I know the answer to, I'll chime in. Worth a shot I guess. Barry -- http://www.piclist.com hint: The PICList is archived three different ways.
