This program should run on any Macintosh with 1MB ram (though only
System 4.2 and later have been tested). But note that this is the
minimal requirement, which will only allow you to play in black&white,
small size and without the sounds, in a just acceptable speed.
To play in color, a 68020 processor as well as Quickdraw 32bit is required.
To play with the sounds, the Sound Manager should be installed (it is by
default with System 7 and later), preferably version 3.2.1 or later to get
more than one sound at a time and to benefit of doppler-effect.
A 68040 processor or a PowerMac is recommended to play in an acceptable
screen size and speed in color.
