I have a 1979 Astro Black Sheep Squadron that I'm looking to sell. Machine is in 100% working condition and has been shopped with new rubbers and lights. MPU originally had battery damage but I fixed that and installed a remote battery holder. Machine is in nice condition and plays great. All 4 chimes work as well. Backglass is really nice with no flaking except for a section in the black in the upper left that was scratched out by the backglass lock bar. Only thing the machine is missing is the knocker assembly as it was removed when I got it. The credit display is a little wonky but works.
Price is $800. I will be bringing the machine to the Pinball At The Zoo show this weekend so you can check it out there. PM me if you are interested. Pics to follow.
