- I'm forwarding this information on Mopac. Mopac 6 is the current
- commonly available version of Mopac, while this announcement provides
- information about Mopac 7. Mopac does semiempirical calculations on
- a wide range of molecular structures (including those of interest
- in nanotechnology). It's major limitation is the number of atoms
- that can be handled, which is "typically" around 20 to 40 (though
- it's often used with more, you just have to be patient or have a Cray).

- Fortran source for Mopac is available by anonymous FTP from some sites.

- Details of the Release of MOPAC-7
-
-
- Until now, MOPAC has been public-domain software.
-
- After I left the Seiler Research Laboratory, and became a private
- consultant, it became inevitable that MOPAC would become a commercial
- product. Under an agreement with Fujitsu, MOPAC-7 has been developed.
- Initially, our plan was to sell MOPAC-7, and get a reasonable return on
- our investment. However, some researchers made the point that, as
- MOPAC had become widely available, it now no longer `belonged' to any
- one person or organization. In recognition of this, Fujitsu decided to
- distribute MOPAC-7 through QCPE to end-users, both academic and industrial.
-
- We finally decided on the following arrangements:
-
- 1. MOPAC-7 will come in two forms: MOPAC-7 (public domain),
- and MOPAC-7.
-
- 2. MOPAC-7 (public domain) will consist of MOPAC 6 plus all
- donated code plus essential bug fixes. We hope this satisfies
- the ethical imperative that we do not take commercial advantage
- of freely donated code or ideas.
-
- 3. MOPAC-7 will consist of MOPAC-7 (public domain) plus work
- commissioned by Fujitsu. MOPAC-7 will be protected by copyright.
-
- 4. Both MOPAC-7 and MOPAC-7 (public domain) will be distributed
- through the Quantum Chemistry Program Exchange. The cost of
- both programs from QCPE will be the normal QCPE cost.
-
- 5. In order to receive MOPAC-7, users will be required to sign a
- non-distribution licence.
-
- 6. MOPAC-7 will consist of source code, command files, test-data,
- and hard-copy manual.
-
- 7. Users can modify the source code, port the source code to new
- platforms, and in general make whatever changes they want,
- provided the copyright notices are not altered.
-
- 8. All donated code will be acknowledged. Some donors will be
- referred to as `authors' in the current version.
-
- 9. Organizations who want to modify MOPAC-7, and distribute the
- resulting modified code, will need to obtain a special license,
- in which case they should contact:
-
- Kumiko Iguchi
- Manager, New Business Development
- Applications Software Planning
- Information Systems Division
- Fujitsu America, Inc
- 3041 Orchard Parkway, San Jose
- CA 95134-2022
-
- Tel 408 988 8012 x 226
- FAX 408 492 1982
-
- 10. The anticipated date of release of MOPAC-7 in January 1993.
-
- We now recognise that MOPAC is truly a cooperative development. Authors
- in MOPAC-7 include researchers in Ireland, Japan, the Ukraine, and Israel,
- as well as from the United States. In recognition of the changing
- status of MOPAC, many of the older, very informal, arrangements have had
- to be changed. For example, donors must formally agree to allow their
- contributions to be placed into the public domain, and ported copies of
- MOPAC must satisfy tests before they can be distributed. To a large
- degree, one effect of these changes is to allow us to increase quality control
- over the program. Because users are not allowed to distribute their
- improvements without a special license (see 9 above), a mechanism is
- being developed to allow their improvements to be included in the next
- public domain release of MOPAC.
