Salutations,

Here are the EAGLE files for the 3 PCBs that I designed to control Golden Spike.

The REV-B DMD controller board incorporates the wire mods I made to REV-A, but
has not yet been fabricated. REV-A has been demonstrated to work, with the changes
to the clock circuit as shown in page 1 of the REV-B schematic. I have included
REV-B in case anybody doesn't want to cut-and-jumper.

I have also included the final, stable, versions of the Golden Spike programs for
the DMD and main Driver Board to show how to control them. They can be opened with
Visual Studio or the Arduino IDE. You may need to re-select the required libraries
from the folder for the Main_Controller program in order to compile it; the NeoPixels
won't work without it.

I hope these files help you with designing/building your pinball machine!
