Aaron, If you get any feedback on this I'd appreciate it if you could pass it on to me. I looked at doing this a few years ago, but felt that a uP would not be fast enough to do the bus stuff and all the other things I needed to do. Maybe I was wrong,and someone on the list knows better. Nec do a gpib chip set as do Texas instruments (search their website I don't have the details here) For my project we finally used a GPIB to RS232 converter, as it turned out that only very few customers needed GPIB.
