I also have the picbuster program but I have no docs. If you have a readme or doc file please e-mail it to me. I am using the Microchip PICSTART 16B1 programmer on COM2. When I run the picbust program I get an error that states that it can't find the PIC device. I have tried all of the common switches -? /? /h and so on. Thanks in advanced. JIM
