- A quick gopher search tells me that you might be interested in Macmimic -
- Demo versions are available from (among other places)

-
- This is a demo of MacMimic version 2.0 as a BinHexed self-extracting archive.
- MacMimic is a molecular modeling application for displaying, building and
- comparing molecular structures. An authentic implementation of the state
- of the art molecular mechanics program MM2(91) is included.
- MacMimic runs on Macintosh II and Macintosh Quadra computers and is de
- signed
- for a 256 color monitor. An FPU and 32-bit Quickdraw is required.
- MacMimic is System 7 friendly and has extensive Balloon Help. Balloon Help
- is only available with System Software version 7.
-
- The MacMimic demo is the same as the full version with the following
- exceptions:
- The demo does not include MM2(91) and it can only Save, Copy and Print
- structures with a total of ten atoms.
-
- You may find the demo useful for exploring molecular surfaces as dot surfaces,
- or for visualizing PDB files (Brookhaven Protein Database).
-
- The author of MacMimic is Anders Sundin.

- Molecular modeling with MacMimic.
- MacMimic is an application for the display, construction and
- comparison of molecular models in full 3-D. It runs on the Macintosh
- II family of computers with a 256 colour monitor and 2 MBytes of
- memory.
-
- The Macintosh interface.
- The Macintosh interface is fully implemented. Undo works on every
- command that changes the structure of a model. Copy and paste can be
- used to move models between display windows or to the Scrapbook.
- Printing in b&w or in colour can be done directly from MacMimic, or a
- picture of a model can be copied from a display window to be included
- in a word processing document.
-
- The display of models.
- MacMimic can display and handle structures with up to 32000 atoms. A
- large number of models can be displayed simultaneously in each of the
- windows of MacMimic. Models are displayed as stick or ball-and-stick
- models, each with toggable attr.
- ibutes such as atom labels, atom index
- and stereo. Colour is used to indicate atom type, but individual atoms
- or whole structures can be painted in other colours. The 3-D
- impression of models is improved by a configurable depth cueing.
-
- The input of structures.
- In addition to documents created by MacMimic, structures can be input
- from the MolLib library of structures, or obtained from a database as
- a PDB file (Brookhaven Protein Database file) or as an XR file
- (Cambridge Crystallographic Database file).
-
- The construction of models.
- MacMimic has a powerful structure editor which can modify existing
- models or create new ones. Atom type, charge and hybridization can be
- set for any atom. The bond lengths and the number of ligands are
- automatically adjusted. A set of substituents is available from a
- palette to make instant substitutions of any monovalent atom. The new
- dihedral angles and bonds are adjusted to make a (locally) low energy
- conformer. Any two models can be joined (substituted) or fused to
- create spiro compounds or complex ring systems.
-
- The comparison of models.
- Pseudo-atoms can be placed in the geometrical center of a number of
- atoms, or in the extension of a bond. Models can be compared by
- superimposition. Up to eight models can be superimposed (RMS fitted)
- simultaneously.
-
- The energy minimization of models.
- The MacMimic package includes the molecular mechanics program MM2(87).
- All computational options (for instance dihedral drivers, restricted
- motion, etc.) of MM2(87) can be accessed through an interactive input
- interface. MM2(87) can be run as a background task.
