 OK, I've got an HP X-Y display with
 the older power cord connector,
 where the three pins are round instead of two being blades
 and the
 only the ground pin being round.? The entire plug
 socket is also
 rounded instead of angled.
 I've tried to find a relevant picture on the interwebs, but
 you try
 googling "power coord connector" sometime and see if you can
 find the
 older oddball you're looking for...
 Hopefully my description alone is enough to aid someone in
 identifying
 the exact standard/specification for this kind of
 connector.
 I'm looking for cords that fit the connector.? I will
 try to remember
 to take a picture with my phone on Wednesday when I am down
 at the
 museum, if we can't figure it out by then.

If you search ebay for 'oval power cord' you will find many for sale.
Never cheap though.
