743 VME board

I was looking through my hardware to find other PA stuff that probably works,
and I remembered that I got one of the 743 VME boards a while back.
then I remembered why I had never tried it before:  it has a funky serial
connector that I've never seen before.  it looks vaguely like a DB9,
but half the size.  does anyone know where I can find cable for this?
or even what it's called?  I could google but I don't know what to
search for.
