Driver Board Gottlieb System 1

New DRIVER BOARD for Gottlieb System 1 pinball
machines.

Replaces A3 driver board PB00-D110 in Gottlieb System 1 games.
This new board has several improvements over the original:

• Higher voltage rated transistors for longer life
  
• Logic level FETs for higher efficiency & lower heat
  generation
  
• Higher current rated ULN2803 replacing obsolete MPS
  transistors
  
• Simplified schematic using only one transistor type
  
• Printed component designators and connector functions
  directly on the board.
  
  
  
  Also, most of the component designators are the same as
  original so that the original schematics can still be used.
