Are you absolutely sure that it isn't a 16F628A ??? > C:\Program Files\XWisp\xwisp.py COM1 target=16f628 verbose go tut2_1 I think it's "target 16f628", no "=". Finely, XWisp2w from www.robh.nl is easier to install, lower "footprint" when run and faster. Also supports more PIC types if used with the "patched" firmware delivered together with the latest XWisp2 distrubution (but also works OK with the "standard" firmware...).
