Compaq Armada 1500C AC Adapter
 

I was given a Compaq Armada 1500c notebook. Unfortunately there is no
AC adapter with it. The adapter socket is kind of stange looking, it
has four pins sticking out of it instead of the usual round AC adapter
socket. I wonder if anyone can provide a pinout of this so that I can
cobble together a replacement. I do know that the machine uses 14
volts dc. Any help on this would be appreciated.

TIA
