monly covered in a junior- or senior-level instrumentation course. The program should not be considered a tutorial on HPLC or chromatography in general. Instead, it simulates very accurately the behavior that would occur if a student made the same choices and performed the same manipulations on a real instrument. As such it provides a wealth of first-hand experience about the characteristics of liquid chromatographic separations.

Videodiscs provide quick, random access to a large number of short video c l i ~ and s images. but the amount of mat e r ~ a ava~lable l can make it difhu'lt to find the particular video r l i or ~ imaee that is needed. Com~utercontrolof the videodisc playe;can help by providing more convenient search capabilities and controlling video playback with the click of a n on-screen button. V~deodiscBrowser 2.0 takes wmputerized videodisc control one step further by providing many descriptions and points of view of a videodisc, each designed for a different way you can use video. It can be used with any videodisc for which descriptive data are available and can be customized to meet individual needs. AMacintosh version has already been published by JCE: Software (6).
About This Issue John W. Moore, Editor Jon L. Holmes and Nancy S. Gettys, Technical Editors University of Wisconsin-Madison Madison, WI 53706-1396 How to Use These Programs WinDNMR can be used either a s a lecture tool or for individual study and experimentation by students. I t is easy to learn to use the program, and so students can quickly develop t h e facility needed for individual study. WinDNMR does not simulate operation of a n NMR spectrometer, but rather deals with the changes that occur in spectra when chemical shifts andlor coupling constants are varied. Some of these NMR concepts are suitable for the sophomore organic course; many are more sophisticated and would be useful only in an advanced undergraduate spectroscopy course or in a graduate-level NMR course. As a flight simulator introduces pilots to the situations they may encounter, so a n instrument simulator provides a very realistic introduction to the operation of a scientific instrument. Students can easily and quickly practice making the decisions that will need to he made when they operate a real instrument, and a much broader range of chromatographic separations becomes available to them than would be possible with a real instrument. The pedagogic advantages of using the simulator both before and after students operate the real instrument are enormous. Videodisc Browser 2.0 provides simple and convenient way to show to a class video clips from three JCE: Software videodiscs: The Periodic Table, ChemDemos, and Titration Techniques (7,8, 9).I t can also be used in advance of a class or other presentation to prepare a script linkingvideo clips from different parts of the same side of a videodisc; these can be easily played hack in whatever sequence a teacher has chosen ahead of time.
Hardware and Software Requirements Programs in Series D of JCE: Software require Microsoft Windows version 3.1 or later and associated hardware as defined by Microsoft. We recommend a n IBM-PC or compatible computer with a 80386 or higher processor, a minimum of 4 MB of memory, a hard disk, one floppy disk drive to install the software, a mouse, and a Windows-compatible graphics card, such a s a n IBM VGA or Super VGA adapter with a compatible color monitor. DOS 5.0 or later is highly recommended. Supplied on 3.5-in. disks. There are additional requirements as noted below. For Videodisc Browser 2.0 a n 80486 or greater processor, a t least 6 MB of RAM, and a 13-in. or larger monitor are strongly recommended. A Windows MCI driver appropriate for your videodisc player must be installed. Drivers for Pioneer (except the LD-V6000 series) and Sony players are included with the Videodisc Browser 2.0 software. Consult your videodisc player dealer about obtaining Windows MCI drivers for other players. A Level 3, CAV videodisc must be connected to vour comnuter throueh a se.laver " rial port with an appropriate cable. Supp(~rt(dplayers include Pioneer 1.1)-VP200. LD-V4200. LD-\'4400. and 1.1)V8000; Sony LDP-1200, LDP-1450, LDP-1500, LDP-1550, LDP-2000, and LDP-3600. Avideo monitor, such as a television set, is needed to view the video.
