Power[edit]

  • 5V Power comes from the USB
  • 3.3V regulator on the RETRO-EP4CE15 Card installed
    • H2 pins 2-3 shorted on the RETRO-EP4CE15 card
    • Routes 3.3V from the 3.3V regulator to the J1 I/O connector
  • Power Distribution card
    • Gets 3.3V and GND from I1 on RETRO-EP4CE15 card
      • 2 sets of wires
    • Distributes 3.3V and GND to SD and DB-25 cards

Connectors[edit]

P2 - PS/2 Keyboard[edit]

  • Not every PS/2 keyboard works at 3.3V but many do
