A final example in this category is ChemDraw (Stewart Rubenstein, Somerville, MA), which probably uses connection tables but does not have substructure searching or interfacing with other software. ChemDraw appears in this book see Chapter 3) because it is probably the most user-friendly package on the market for entering chemical structures and producing high-quality output. Unfortunately, it is available for use only on Apple Macintosh computers. 

Apart from the classically invoked facility of on-line data collection and recording made possible by computer-based experiments, we chose to use HyperCard - running on Apple Macintosh computers - for two of its main characteristics match our research aims closely. 

The software for traversing the Web is called a browser. The earliest of these were Mosaic and Netscape Navigator. Both were free and became widely used. Microsoft s Internet Explorer is a more recent entry. Browsers run on UNIX workstations, personal computers, and Apple Macintosh computers (it has been estimated that because Macs have enjoyed popularity among scientists, these machines have been the most used platform for authoring Web documents).

A rigorous mathematical model was developed for this system using the correlations and data presented in Refs. Al and A2. The model enabled the sizing of the column and the optimization of tray spacing. It was run on the APPLE Macintosh (512K) personal computer. 

The computer program written to describe and implement the mathematical model was run on an APPLE Macintosh personal computer. A listing of the program is not included due to limitations of space. However, sample results obtained from the program for the particular design problem considered in this project are given in Table G4. 

An integrated, modular system for molecular visualization and computation of organic, inorganic, peptide, and polymeric compounds. Stick, ball-and-stick, and space-filling representations. 386 and 486 PCs and Apple Macintosh II. 

Fully Compatible with IBM PS/2, PC. XT, and AT Systems or 100% Compatible Systems Operating in VGA, EGA, CGA or MCGA Modes. Macintosh n and Mac LC Computers, Apple 0 Computers, AT T/ Olivetti Systems, and DEC VT220 Terminals... 

Graphical simulations were performed using the graphing calculator function on an Apple Macintosh PowerPC personal computer. 

As part of their efforts to employ parallel computers for molecular dynamics simulations, Schulten and co-workers generated a series of MD benchmarks based on their own program on a wide range of machines, including an Apple Macintosh II, a Silicon Graphics 320 VGX, a 32K-processor Conneaion Machine CM-200, a 60-node INMOS Transputer system, and a network of Sun workstations (using Linda).2 8 j e benchmarks demonstrated that the program runs very efficiently on many platforms (e.g., at sevenfold Cray 2 processor speed on the CM-200 and at Cray 2 processor speed on the Transputer system). 

When I think of ESD, I always think of the same instance. A few years ago, I was working on an Apple Macintosh. This computer seemed to have a mind of its own. I would troubleshoot it, find the defective component, and replace it. The problem was that as soon as I replaced the component, it failed. I thought maybe the power supply was frying the boards, so I replaced both at the same time, but to no avail. 

Finally, we come to the venerable old man of the graphical operating system world, the Apple Macintosh. Apple was founded by Steve Jobs and Steve Wozniak. Wozniak built the first Apple, and was the technical wizard. Jobs was the sales and marketing guy, and together they built and marketed the Apple II, which Jobs dubbed the computer for the rest of us. The Apple II was an immediate success, as it had color graphics, and useful applications such as Visicalc were available for it. For 1977, it was quite a spiffy machine. 

For users of Macintosh computers the main differences (which are still rather minor) stem from differences in mouse and keyboard. The Macintosh mouse has only one button, so that the equivalent of right-clicking on a Windows machine is achieved by the combination CTRL + click. Many operations performed on a Windows machine with the CTRL button instead use the COMMAND button on the Macintosh keyboard, or sometimes the OPTION or Apple key. The Microsoft Excel User s Guide nicely juxtaposes the corresponding Windows and Macintosh keystrokes where these are different. But, again, these are only superficial, easily learned differences the underlying spreadsheets appear to be identical. 

Another source of information that already has been mentioned is the QCPE.2" Its primary focus traditionally has been on the research community, but some of the materials can be useful to the instructor. For a source of computer software aimed exclusively at the educational community, one can best turn to the Journal of Chemical Education Software.On a subscription basis, one or more diskettes are released each year for both the IBM and Apple Macintosh platforms. (In general, a given software package is not released on...
