Quoted from SteveFury:
So this circuit isn't really to prevent the machine from not knowing when the game is over, but to prevent a false vend when powered up.
Thanks for explaining this Steve as Steve Young did not bother going into the details of this like you.
I actually have a Space Odyssey 2 Player, but wanted this machine because of how much fun I had at the arcades back in the 70's with Space Mission. This was my first machine to launch me in the hobby over a year ago. More artwork to see on "SO" and less to fix was my reasons for wanting this title compared to "SM".
As far as a comparison to "SO76" they are completely different feels and style for playing. My wife loves "SO" and I as well so it is a keeper. "SO" is a great feeling when you can nail the flag at 1000 points which is hard and getting the horseshoe for that advance bonus. She likes "SO76" but I really like it as that center Kickout hole makes me want to be a better player so I can score what I want, when I want, but denies me that quite a lot, so I try again, etc and is also a keeper.
You can check my profile for other machines I have if you like. 3 are currently working, all 100%, "SO, SO76", and 4 Square. All the others are major projects with a 1973 Williams Gulfstream being currently restored and will be finished sometime late fall or early Winter. I am a big Williams fan for fun and dependability, but rate Gottlieb as having the best overall games in general.
Quoted from SteveFury:
I also noticed you have a Stardust. This is really a coincidence.... I had almost picked one of those up a couple months back as another project machine.
Just picked this one up at a local auction, Stardust was one I was thinking of doing a quick fix and selling but after Chris Hibbler said how fun it is and that he wanted one I may just have to do a major restore on it and see if I want to keep it. I love the colors and like the layout of the Playfield is in good condition. Great Backglass art although mine is shot condition wise (3). Cabinet wood/paint in good condition, coin door is shot.
A lot of the machines I pick up are 1 step away from the dumpster, so I save them. They gave me a lot of fun as a kid so I want to give back and keep them from the parts bin.
I love fixing these things more than playing them, but only by a little.
