Phimal is a five-band graphic equalization system designed to run on a PC
containing a Texas Instruments TMS320C54x DSKplus board (DSK). It
samples an audio signal connected to the DSKplus audio IN jack. It features
a graphical user interface displaying a menu of commands, the current
state of the five bands, and a time graph of the equalized signal.

I. Using    Phimal
-------------------
To run Phimal, type "equalzr.bat<Enter>" at the DOS command prompt. This
batch file starts the host and DSKplus parts of the application. The files
main.obj and equalzr.exe must have been built in order for this batch
file to run properly.

The following is a summary of commands:
    PageUp/PageDown         Change the vertical scale of the time graph.

    Up/Down/Right/Left      Adjust the equalization. The highlighted band
                            is the one which can currently be modified.
                            Use Up/Down to equalize the highlighted band.
                            Move to a different band by using Right/Left.

    ESC/Q/q                 Quit the application.

    P/p                     Pause the time graph.    

III. System Requirements
------------------------
Phimal requires an 'C54x DSKplus board connected via the PC parallel port. 

Phimal also requires the file egavga.bgi (part of the Borland Graphics
Interface), and an EGA/VGA display. Make sure this file is in the current
directory where the equalzr.exe file is located.

The following is a list of files in this application:
     hi54x.cpp		DSKplus/PC host communications functions
     eqgrphcs.c         graphics functions
     eqgrphcs.h   
     eqhost.cpp		main() function
