Subject: Deal 'Em phase 3 Conerted the driver to use an HD6845, as the Hitachi part was on the PCB, while also using it to generate the VBLANK, rather than hardcoding a value. Added the pulldown resistor to the network, and added all the conditional inputs. Please note that on the later Cabinet Types (Ready Steady Go-1 onwards), the 10p slot is locked out (location of the true register for this is unknown), but the input setting is correct - you have to use Coin 2 or higher to get money in.
