it is amazing really how these old machines still keep going, the one i have dodgied up enough to put back in to service as a little money maker in my shop, it has made me wonder how much cash this thing has turned over since new in 1986, when i got my one for the shop, you can see it spent a long time in service in arcades, and was shut down and stuck in storage for along time collecting dust, till the guy i bought it off firede it up and sold it to me. I guess maintence now will be more regular to keep it going, i look at under the playfield and see how many times things have been fixed on the fly to keep it in service. im hoping to do the same in my cafe lol. wonders how many times the ball has been fired up the shoot, and how much coin it has made. i doubt they thought in 2011 this thing would be out making coin again, lol, id say most of reason for it lasting so long is arcades trying to dodgy things up good enough to keep it going a little longer and milk as much work out of it as possible. i doubt a modern day computer will last this long.
