plug tip for thinkpad ac adapter

[phr@netcom.com (Paul Rubin)]

I need a 755-style plug tip for the portable AC adapter,
FRU P/N 85G4952.  This is the adapter that hangs from the wall
by a short IEC cord.  It is shipped with a tip for the 701 and
a tip for the 755 and you plug the appropriate one in, normally
permanently (you can pry it out if you try hard, but it's a pain).

Does anyone know where I can get one of these tips?  Is there an
IBM part number for it?  I called tech support about getting another
one last time, and I had to get a whole new power brick.

Do any 701 owners out there have a spare 755 tip they want to sell me?
I'll happily pay say $10 for one, or will cut a custom CD-ROM for
you if you can get me the data somehow, or whatever.

Thanks

Paul
