C1 Z80 Proto Board

Schematic

     The Z80 Proto Board has a 40 pin 0.1" pitch dual row female connector on its lower edge that plugs into the 1731 Z80 Backplane to allow communication with the 1730 Z80 CPU. All of the Z80 signals are labeled and brought up to a row of pads and the rest of the card is simply a grid of plated through holes on a 0.1 inch grid: 30 holes horizontally by 20 holes vertically with two smaller 5x3 grids to the left and right of the backplane connector.
