Hi! Has anymone of you ever coded a GPIB (or HP-IB, or IEEE-488) interface using any of the PICs. I am not sure if its hard, I didn't have a look at the bus specifications yet (since I don't have them...) It would be great if anyone could help out, with bus specs, failure or success reports, or, even CODE (Well, I guess thats too much to ask for) Bye, happy PIC'n Aki
