Has anyone had success getting a PIC16F887 to work with this
bootloader? From what I read the PIC16F887 is the replacement part for
the PIC16F1877. It has an internal oscilator.

As far as I can tell the program memory seems to line up. Are there any
reasons it shouldn't work?

Using the 16f887 bootloader code I changed the part number and fuses,
compiled and burnt it but it doesnt seem to do anything with the
windows bootloader software.

Thanks,

Mark
