Yet another iteration of the PCB

  • Signal tracks are now 20 thou
  • Changed 1mm power track on bottom to 80 thou track on top
  • Changed 1mm ground track on top to ground plane on bottom
  • Changed VGA,PS2, LED, Switch and spare I/O headers to 10pin (instead of 12)
  • Added power led pin for front panel from 3.3V via 390Ohn resistor
