Major Havoc -> Tempest Adapter Schematic

Could someone scan in the schematic for the adapter board
to put a Major Havoc into a Tempest? I've noticed there are
subtle tweeks to the multiplier values for the different
game implementations, and was wondering if this circuit was
identical to that on a Tempest.

Also, does anyone have any opinions why the Quantum PCB
HAS the XY correction circuit, when it shipped with an
Ampliphone monitor?

I was wondering, Zonn, which games you have tried your
modified WG monitor that drives the deflection amps from
the unregulated supply? On games with the correction
circuit, is the display "overcorrected" now?
