SPECIAL OFFER
With every copy of the PC version of the MOPAC6 package (QCMP 137) which is purchased at the regular price we are giving away a free copy of the orbital drawing program PSI/PC92 (QCMP 143). You must specify that you want to receive the orbital drawing program at the time you order the MOPAC6. This version of MOPAC6 comes with three separate executables and memory extenders for calculations from 30 HEAVY and 30 LIGHT atoms up to 70 X 70. To do the smaller calculations you need a 32-bit chip and at least 8 Mb of RAM. For the largest calculations you need 16 Mb of RAM. MOPAC6 is shipped on two HD, DOS-formatted diskettes and has been tested in a WINDOWS environment. Richard W. Counts/QCPE |
