I've got an ODS 836 DB-9 to fiber token ring transciever. I don't know if
it works since I've only got one, no power supply for it, and no fiber.
It takes a 12V DC power supply, 2 female pin sockets side by side in an
~5mm round male insulator all inside a ~8mm round recess, apparently held
in by friction alone (I have never seen this kind of connector elsewhere).
It's in a 5" x 2" x .75" possibly watertight machined steel housing
(there's a rubber gasket between the 2 halves). If anyone wants it, it's
free to a good home. I'm in College Park, MD 20740.
