This directory contains three files. Only students taught in IA Materials and Mineral Sciences or IA Geology at Cambridge University may copy them: README A plain text file, you are reading it now! Crystal_Folder.sea.hqx The executable Crystallography Courseware for Macs, in BinHex format. Double click on this file to download this file in binary format to your local machine. Then decode with BinHex (if this does not happen automatically) and then double click on Crystal_Folder.sea, which is a self-extracting- archive and will unpack into a folder called Crystal_Folder. Then double click on the file called Crystallography.sea to unpack the program, then run it by clicking on Crystallography. Ask a friend or your local computing officer if you need further help. xtallog.zip The PC version of the same program. Download to your PC by double clicking on this file, then "unzip" using the unzip utility to obtain an executable file with the CourseWare. Any problems, please send an e-mail to me, Simon Redfern (satr@esc.cam.ac.uk). 16th October 1996
