    Royce,

        The PIC-SERVO SC didn't exist when I wrote this article, but the
        schematic you refer to is correct for that part.

        The one in the article is from section 6.2 on page 23 of:
        http://jrkerr.com/psdata.pdf which is a more complicated circuit
        since the PIC-SERVO and PIC-ENC were separate processors in the 
        olden-days.

        You are much better off with the new PIC-SERVO SC since it's a
        single chip, and it's cheaper than the old ones.

        I think $29 for a single-chip PID control system with all the
        features this one has is an incredibly good deal.

        Yes, you could invent it your self and just pay $5 a pop for the
        processors, but I don't have the time to write and debug all
        that software, so I just buy mine.

                                -Alan
