I have two machines from 1971 - Drop A Card and 2001.
Not only do they have the occasional part that needs replacing but the company who made them is not even in business any longer! I reached out to a Gottlieb family member and he said the games must have been purchased 48 years ago. I told him I just bought them within the last 3 years! What gives?
I am no longer stocking up on pinball machines for future enjoyment as you simply cannot count on the manufacturer to keep them up and running now or later.
I should have learned my lesson when Polaroid would not give me a refund on the instant film I had been hoarding from the 70's when the recent pictures I took with it came out completely white.
You all have been warned, things are not the same as they apparently never were.
Have a great day and don't take this life so seriously, no one makes it out alive.
