Can anyone tell me where I can find an FPU emulator for the macintosh, 
preferably as shareware on the internet.

Thanks!

At most of the mac ftp sites (sumex.stanford.edu, etc.) there is the 
control panel "Software FPU" which works quite well.  It's shareware, 
$10 I think, for 68K and a native version is also available from the 
author for, I believe, $20.

Dear Netters,

where could I find a definition of the PDB format? I'd like to have
a description that is as complete as possible. And of course I would
prefer it in electronic form...

The following description is taken from the RasMol manual, written by Roger
Sayle(ros@dcs.ed.ac.uk)

PDB Format:
as Fortran: FORMAT(6A1,I5,1X,A4,A1,A3,1X,A1,I4,A1,3X,3F8.3,2F6.2,1X,I3)

Column:		Content:
1-6		'ATOM' or 'HETATM'
7-11		Atom serial number (may have gaps)
13-16		Atom name in IUPAC standard format
17		Alternate location indicator(chain) A,B,C,etc.
18-20		Residue name in IUPAC standard format
23-26		Residue sequence number (order as below)
27		Code for insertions of residues (ie 66A & 66B)
31-38		X coordinate
39-46		Y coordinate
47-54		Z coordinate
55-60		Occupancy
61-66		Temperature Factor
68-70		Footnote number

Note that this does not include the format of PDB headers which start with a
different set of codes in columns 1-6 are allow unlimited(?) text in columns
7-70.  Header codes include TITLE, SOURCE, REF1, REF2, SEQ, and others.
Download a few PDB files to get a feel for header information.

	The document specifying the file format is available via 
anonymous FTP from www.ccl.net in the directory
/pub/chemistry/documents/PDB/PDB_file_format the postscript file is 
pdbformat.ps and there is also a file called official-pdb-doc.ps, as well 
as TeX source.

	Hope this helps,

		Martin.
