Installing the System
WHPA

The WHPA model is designed to run on any standard, IBM or compatible XT, AT, or 386 microcomputer (PC) operating under MS DOS version 2.1 or later. The machine must have a minimum of 640K RAM (Random Access Memory), a hard disk, and CGA EGA VGA or Hercules graphics capability (EGA or VGA is highly recommended). The model will automatically detect and use the math coprocessor if one is present but one is not required.

A hard copy of capture zone plots observed on the monitor may be obtained using EPSON, OKIDATA NEC PinWriter and IBM Proprinter dot matrix printers and compatibles, Hewlett-Packard (HP) Laserjet laser printers and compatibles, and Hewlett-Packard and Houston Instruments pen plotters and compatibles. A summary of the available graphics devices supported by WHPA is provided in Table 2.1. If you do not have access to any of the supported hard copy output devices, you may save plot files in standard HPGL format (see section 5.2.3.2) and subsequently use any number of software packages, such as WordPerfect (see Appendix D), PrintAPlot, or just about any CAD package, to output the plot on other output devices.

To install the WHPA model on your computer, perform the following steps:

1. Establish a sub-directory on the hard disk
MKDIR.WHPA

2. Change directory
CD\WHPA

3. Place diskette in drive A
