Step 1
The Java applet version of PacMan we will use can be downloaded from the developer:
It comes as a single zip file named: pacman.zip (naturally!)
If this web site is no longer available, then use your favorite web search engine (mine is Google)
and search for: pacman java applet
I would suggest creating a new, temporary directory on your hard drive
(I called my temporary drive "games"), and download the file to this directory.
Since it is a zip file, you will also need an appropriate utility to extract or expand the file.
Once you have your Zip utility installed, and have downloaded the pacman.zip file to your PC,
use the Zip utility to "extract" the contents of pacman.zip to your temporary directory.
