where to find info

[Jemison Richard]

Geoff,

Don't suppose you'd have one of those maps in electronic format (or if you
could scan one) and pop it off.  Might be easier if I explained what the
sucker was trying to say.  I can't think of a book on PROMs specifically
right now.  I'm no expert, but I might be able to read your map.  FWIW.
