searching for software

 Hello everybody,
 I would really appreciate some help and information about two kinds
 of software:
 1) X-windows emulators for Mac's (Power Macintosh type) and
 2) Programs to manipulate and visualize nmr spectra that run or in Mac's
 or in X-windows
 I don't mind if they are comercial or free programs, what I have been
 asked for by my Institute are good programs even if they are not cheap.
 Thanks a lot
