Hi Jim out of interest (mainly), do you know the H/W differences between the 16B and the 16C PicStart programmers? Microchip do seem to have a confusing range of programming devices. Since the PicStart 16C kit includes an EPROM 16C, I was toying with the idea of working out the cct, blowing a new PIC, and using that. Partly as an exercise, and partly because the PicStart is a nicer bit of H/W than the cheap & cheerful thing I'm knocking up at the moment... cheers jon N
