Hiho, DIN-5 plugs (the AT-keyboard style) are not difficult to come by. Is there any indication which pins of the socket are for which voltages? Presumably the three positive voltages are on three of the pins, and one or both of the remaining two are ground.. If you have an actual pinout for that connector, it wouldn't be terribly difficult to either cannibalize an old laptop power brick (back in the days when the laptop bricks put out separate +5 and +12 voltages, if you can come up with one) or simply construct a power supply from scratch (I'm sure I'm not the only trilugger with electrical circuits experience).
The suggestion of parasitic power (aka. not needing the power supply---drawing power from the computer's ports) I know is true for Belkin brand devices, as I have one and have used others.. However, my instinct is to suspect that since it requires the two separate potentials, it's not going to be able to power itself from the computer's ports (only the RS-232 port, that I know of, even sports 12v potentials, and newer forms of that standard operate at only 5 volts). Worth a shot, though. Good luck, and let me know if you would like some help with the scratchbuilt power supply idea.
