Hi Steven, > The interface for my programmer is pretty simple, the controller > pic talks to the Sun at 9600 baud half duplex ... Congratulations on getting your PIC programmer going. I guess if you look carefully at your software there is really very little that is Sun dependent. You have gone a long way in implementing "phase 2" of the machine independent universal PIC programmer project. But, and this goes to the heart of the problem I was trying to address, how did you program the PIC in your PIC programmer? David -- david.tait@man.ac.uk P.S. I would be very interested in receiving more information on your project.
