Hi,

I just fetched this via command line FTP (something's wrong with
that URL in Bill's message below - perhaps underscores vs blanks)
and converted it to PDF and posted it.

Verified URLs are:

  ftp://ftp.pwg.org/pub/pwg/mfd/white/MFD_Outline_Nov_08.doc

  ftp://ftp.pwg.org/pub/pwg/mfd/white/MFD_Outline_Nov_08.pdf

Cheers,
- Ira
