ChemDemos is a 12-in., double-sided, 60-minute, CAV-type video laserdisc in NTSC format (it is incompatible with the PAL standard used in many European countries). It may be operated from any videodisc player using a hand-held remote-control keypad or a barcode reader. (Consult the supplier of your videodisc player to ascertain whether it can be used with a barcode reader.)

To make the video presentation visible to students in a classroom either a large-screen color monitor or a color video projection unit will be needed. The size of the monitor (or the need for a projection unit) depends on the size of the class to which the presentation will be made.

If the disc is to be used under computer control the videodisc player must have a serial (RS-232) interface. Software is supplied with the videodisc for both Macintosh and IBM compatible computers.

The Macintosh version requires an Apple Macintosh with a hard disk drive and HyperCard or HyperCard Player version 2.1 or later. Macintosh computers running under System Software version 6 without MultiFinder must have at least 1 MB of memory, System Software version 6.0.5 or later, and HyperCard 2.0 or later. Macintoshes using System 7 or System 6 with MultiFinder require a minimum of 2 MB of memory.

The Windows/IBM PC version requires Microsoft Windows version 3.0 or later and associated hardware as defined by Microsoft. We recommend an IBM-PC/AT, PS/2, or compatible computer with an 80386 or higher processor, a minimum of 4 MB of memory, a hard disk, one floppy disk drive to install the software, and a Windows-compatible graphics card, such as an IBM VGA or a Super VGA adapter with a compatible color monitor, and a mouse. DOS version 5.0 or later is highly recommended. (Run-time Toolbook is included with this issue; Toolbook software is not required.)
