That post is for a software card that includes those games, it's called a Game Chest and runs in a Bluebird 3 Cabinet.
That Game Chest card will only work in a Bluebird 3 Cabinet with the BB3 CPU.
If you had a BB1.5 Dual Monitor Machine, you could purchase individual games to run on it, but your best bet would be to have a BB2 Machine. It's set up with dual 22" Monitors.
There are tons of game titles available for BB2 machines, as well as a few different versions of the Game Chest software.
Hope that helped.
