    This is National Instrument's NI ELVIS Prototyping unit. I'm having trouble finding out what kind of power cord this requires. It seems to have one pin missing, however on opening it up, it seems that there's no physical connection to the board from where the missing pin is anyway so it's just 5 pins.

    I looked it up on their website but it just gives a generic description saying 240V 10 Power cord for $12.

    Hmm, I saw that one too, it seems to be one of their own connectors. Found the same thing on eBay and I don't recognise the connector.

    Would have loved to use this, but I'm not going to pay $100 for a connector when I'm not sure this will even work.

    I'm guessing based on the specifications it must be ±15V, 5V and GND pins.

    Looks like an AMP MTA-156 connector. (or the cheap-o versions like in the above jameco links.. Just need to know pin/pin spacing.. (prob .156" or .100" for the MTA-100 series)

    According to the datasheet on KMOFFETTs link above, inputs are likely ground, +5, +15, -15 and (variable +/-12).

    Oooh, that was heaps useful guys!

    The breadboard comes out easily, however that gives no information on the connection. It's the rear panel that I removed and took a look inside, but that gave nothing either.

    I will try those tips and see what I can get from it.

    My next question though is what kind of adapter/power-supply will provide all 3 outputs? Looking at that eBay link, it looks somewhat like a laptop adapter, but clearly it isn't.

    There are new power supplies available with all three voltages, but they will cost $50 or more. You can do the same thing with three separate wall warts for a lot cheaper. Maybe even free if you in your friends' and families' junk drawers for old chargers.
