Homebrew Servo Controller Issues

Hi,

I've been developing my own serial servo controller for the hexapod I'm working on, using a Microchip PIC16F74.  It accepts serial input and controls up to 20 servos. The servos are connected in ports A, B and D.  Power for the PIC is from a 9v battery via a 7805 regulator.  The servos have a separate power supply from a 6v battery pack.
