NOTES:

1.  Make sure the cocktail pin P20-15 is jumpered over to ground
    for uprights on the Centipede side connector.
2.  Install a jumper from P19-L to ground on the Millipede connector
    This is the ground for the Millipede coin mechs.  The ground on 
    P19-N is the ground for the Millipede service panel.
3.  The P10 connector for the -5 and +12 volts is on the Aud/RegII
    card.  You'll need to buy 2 .093 male molex pins to snap in
    the molex housing.
4.  To access the Centipede color grid, a momentary switch will
    need to be installed as the tilt switch.  The 2 Millipedes I've
    seen do not have tilt switches.
5.  Millipede cabinet uses composite sync whereas the Centipede
    cabinet uses horizontal and vertical syncs.
6.  The Centipede pinout on wiretap shows 'coin door ground' on
    pin P20-X and Start 2 LED on P20-R.  These are not correct.
    P20-X is +22 VDC and Start 2 LED is on P20-8.  I verified 
    this on schematics and on the Centipede harness.  P20-R is
    the TILT switch.
