Running This Program on the Desktop
-----------------------------------

This program was designed to take advantage of the HP palmtop's graphics
hardware.  You can, however, run it on a desktop computer with a CGA or
better display, using the INT5F driver which is included with this
package.  The INT5F driver emulates the HP's graphics mode, allowing you
to run this program (and many others, especially those produced in
recent years with the PAL library) on a desktop PC.

INT5F has two modes: VGA and CGA.  In CGA mode, it uses the CGA's 640x200
monochrome mode to emulate the HP's LCD.  In VGA mode, it uses a higher
resolution VGA mode, which provides a better match to the shape of the
HP's LCD (since it's much longer than it is wide).  As a bonus, in VGA
mode some recent PAL applications will use the whole desktop screen,
even though no HP palmtop has such a large area to work with.  (This program
isn't one of those, however.)

To load INT5F in CGA mode, type:   INT5F /C
To load INT5F in VGA mode, type:   INT5F /V
To unload INT5F, type:             INT5F /U
To load INT5F reversing the colors: INT5F /R (for VGA) or INT5F /I (for CGA)

INT5F was written by Harry Konstas, and is freeware.

You might also wish to try the CGAGRAPH driver, which is included in
the PAL library distribution.  CGAGRAPH is faster than INT5F, but is
larger, requires an EGA or better, and doesn't do full-screen mode.
Most PAL programs will try to auto-load CGAGRAPH if they need it, and
unload it afterward.  The PAL distribution is available from:
