Step 2: Cd-Rom Prerequisites
Check to make sure that your Cd-rom will open and close with a battery pack and make sure that the Cd-Rom will not close on it's own after being open. I have noticed that some Cd-Trays will close automatically after being open for several seconds I'm not sure if this is a Firmware or Software thing so best to check it out.
You can skip this whole step if you'll be using a wal-wart type power supply to power the Cd-Rom Drive I've found that using a wal-wart works best.
Molex Power Connector
2AA batteries and a 9V battery
Start by removing the unused wires from the Molex Connector
you will only need the red and the black wires.
set up the batteries like the diagram and tape or adhere them together.
this gives you ~12V .
Enough to eject the Cd-Rom Drive
Connect and Test the eject button
you may have to reset the cd-rom by disconnecting and reconnecting the molex a couple of times I'm not sure why I had too but once it opens once it will open and close fine until the power is disconnected.
