RE: [CAD_CAM_EDM_DRO] Gecko power requirements

What Doug is suggesting certainly makes for a very clean installation and I
would definitely recommend his p-Break cards to do it. If you already have a
junction board of some sort or you are just in a hurry to get it done I have
resorted to hooking wire to the 5V supply line from the PC drive connectors,
running it out the back of the computer and zip tying it to the parallel
cable to help keep it neat. Some how it seems once I resort to this it just
stays this way and works fine.
