QCMP113.MOPAC:Version 6.0 for the IBM-PC

by RainerKoch and Bernd Wiedel, Institute for Organic Chemistry,University ofErlangen-Nürnberg,W-8520 Erlangen, Germany

This isa completeversion ofthe MOPACversion 6.0 system whichhas heretoforeonly beenavailablefor selected workstationsand mainframes. Itis a fully certified version.

As onemight expect,this systemrequiresafairly well-configured PC.Thefollowing hardware requirements should be adhered to rather carefully.If you donot now have these capabilities or will not be obtaining such capabilities, do not order this system:

  • PC based on CPU 80386/80486
  • Numeric coprocessor 80387/487 or Weitek
  • Minimum of 8 Mb RAM
  • Extensive freedisk space on hard disk of 10Mb or more
  • DOS version 3.3 or higher
  • DOS-Extender (For Recompilations Only)

QCPE willbe deliveringthis systemin acompressed form on two 750 Kb 3 1/2 inch diskettes.We have never before deliveredanything ina compressedform,but expectnodifficulties.Theexecutablefilefor decompressing everythingwill accompanythe shipment. Instructions forthis process will be contained in the documentation.

One ofthe filesyou willreceive isanexecutable which is preset for dealing with structures of up to 25 heavy atomsand 25lightatoms.Ifyoufindit necessary torecompile from the source files, you will need to be in possession of the following:

PHAR LAP memory extender NDP FORTRANCompiler (Version 2.1 or 3.1 but not 4.0)

The documentationlists sourcesof a DOS-Extender and the FORTRAN Compiler just mentioned.

Lines of Code:30,000 FORTRAN 77 (NDP FORTRAN)
