Congrats on getting and saving the Apollo.
I found even back in the day that Williams games were always fun for a kid......and adult. Played them quite a bit of in the '70's.
Never played Apollo but would like to some day. Great art all the way around and very interesting Ruleset.
Space theme is cool as I have a Williams Space Odyssey and love the artwork as well.
For me fixing the old machines is over half the fun, but I still love to play as well, especially after I save a machine from the dumpster such as yourself.
Have fun fixing and playing as you have a keeper.
