 Gerben, 

 Had problems mailing you direct - so I'll send the reply through the

  I should think it'll be easy. The NMI routine should be the same, and
  all you need to change is the addresses it uses to access to 1770 chip.
  My program has two set of address in it - the first BBC B+ compatable,
  the second Master compatable.
  The ADFS internals are un-important.

  I'll did it out when I go back home.
