Subject: GSAS has been ported to Macintosh
Reply-To: rietveld_l@ill.fr

I have ported GSAS to the Macintosh computer. This was developed on a PowerPC
Mac with a 604 processor and has been tested machines with the 601e and the G3
processor. Run times are very similar to those on PC's with similar clock
speeds. Older Mac's with 680x0 processors are not currently supported.

It is now available as shareware. 
Since the anticipated user base for this software is small, the price is a bit
high for shareware.
The license fee has been set at US$100 for academic users.
                         And at US$500 for industrial users.
A site license fee has not been defined.

The software package is available by FTP from 'MacGSAS.CNCHOST.COM'.
Unfortunately Concentric, my IP does not allow anonymous FTP access to this
site. So I have set it up with two users, one with full privileges and one with
read only access. 

Please contact me for further details.

I am willing to discuss any and all details of this project.
