Appendix B Suggested PC configurations

CAL courseware may be used on rather small and cheap PCs, but if one wishes to take advantage of the existing off-the-shelf titles and of multimedia in general, one needs to acquire a minimum configuration.

In 1990, a certain number of companies agreed on a common standard configuration known as MPC (for Multimedia PC). IBM did not join, estimating that the suggested configuration was not powerful enough.

This standard has already been upgraded twice since, following the market trends and the applications offered. Today it includes:

· 486 microprocessor
· 4 Mb of memory 160 Mb of hard disk
· a 16-bit sound adapter a CD-ROM XA drive (300 Kb/s)
· VGA display (64,000 colours)
· WINDOWS and its multimedia extensions.

Although this configuration represents a considerable enhancement of MPC, since it can run applications bought off-the-shelf, it may not be powerful enough to develop one's own multimedia applications.

A reasonable development work station should comprise:

· a 486DX2 microprocessor
· a 8 to 12 Mb memory
· a 200 Mb hard disk
· a SVGA display
· a CD-ROM XA drive (300 Kb/s)
· a 16-bit sound adapter

to which one may connect, depending on the technologies one wishes to use:

· a videodisk player
· a video compression/decompression hardware and/or software
· a still frame (image) capture adapter
· a scanner

and the appropriate software:

· presentation and/or authoring system
· graphics systems
· image handling
· sound processing
· video processing
· animation production and processing.

Existing PCs can be transformed at a reasonable price into a multimedia station in order to take advantage of offered titles without having to invest too much:

· adding a CD-ROM drive is probably the first step to consider; it may be important to make sure to have a CD-ROM drive from the last generation (called "multisession")

· a sound adapter can then be added (or at the same time as the CD-ROM with which it is frequently offered as a package); the highest quality is currently obtained with 16-bit adapters.

With this equipment one can use most of the existing titles, noting however that:

· if compressed images and/or video files have to be used, a decompression adapter and/or software has to be added;

· if the learning material is offered on a videodisk, a videodisk player and an overlay adapter will be necessary;

· if one wishes to digitize images and/or video, a digitizing adapter and/or a compression/decompression adapter will be necessary.

Warning: remember that adapters are different according to the PC bus used.
