Hi Try looking in almost any issue of Everyday Practical Electronics. They use ISP in all their pic projects (18c84 but it should be pretty standard). The software is available from their ftp site at ftp://ftp.epemag.wimborne.co.uk/pub/pics/ I can look out the circuit details if you want. Hope it helps.
