I have a 1976 bally freedom machine that I inherited from my grandfather in the early 90s. it was right on the cusp of digital pinball and from what I understand there are versions of this machine out there that are solid state. unfortunately it broke a long time ago when I rolled the scoreboard over into 6 digits and I haven't been able to play it since. it's now sitting in my garage waiting to be restored, collecting dust for decades. I have a long term plan to bring it back to life and luckily there is a prominent pinball youtuber that walks through the restoration of the exact same machine I have. I hope my plans come to fruition some day and im sure its gonna cost me more than the ~$1500 it is worth fully restored. looking inside at the guts, it is an absolute wonder of mechanical engineering.
