I am looking for some information on the three pin power cords that were
used, among others, by HP.

On one end is the standard 3-pin 15A 120v line plug; on the other end is
an
oval body with three round sockets inside it. It looks like the old TV
cheater cords, but has a third, ground pin.

Does anyone know the name of this connector?

Does anyone know where I could obtain a few? Mouser doesn't have them.

Thanks in advance and 73,

I don't know of a name for them, but you can purchase them at your local
Singer sewing machine company. They use the same plug.
