To those of you who are interested in more information about HyperChem:
as a member of the HyperChem development team, I would be able and happy
to answer any questions you may have.  I don't want to make commercial
postings to the net, so I will only give a couple of quick answers to
the above questions here.  If you want any further info, please e-mail
me at:
           michael at bobino.bri.nrc.ca or moller at hyper.com

or send e-mail to Tom Slee, our Product Support Manager, at:
           slee at hyper.com

Quick answers:
1) HyperChem does link to other Windows applications via DDE and the clipboard.
   So, you can run HyperChem from Excel macros, or from Visual Basic programs,
   for example.  You can also transfer drawings of molecules from HyperChem
   to a word processor or drawing program.
2) Yes, you will need a big PC to simulate proteins.  Here at BRI, I use a
   25MHz 386 to display papain (212 residues, 3300 atoms), but this machine
   is too slow to do many energy calculations on such a large molecule.  You
   will need a 486 for that.  However, HyperChem will run perfectly well on
   a 386SX (I use one at home), for small molecules (about <300 atoms).  For
   those with BIG molecules, we are planning to release a version of
   HyperChem for SGI workstations.
3) Yes, HyperChem does do energy minimizations, and will also do molecular
   dynamics, while continuously updating the display.  HyperChem can do
   both molecular mechanics and semi-empirical quantum calculations.
4) HyperChem can display in side-by-side stereo, so you will need a pair
   of stereo glasses to see it.  One can also export a stereo
   picture to a word processor, and print it out for viewing.

HyperChem has a number of other features, which I will be glad to describe
via e-mail.
