These are the machines that I have sold or traded. They include 3 pinball machines plus a shuffle alley (bowling).
My first machine was a Gottlieb Atlas machine. I was lucky enough to obtain that machine through marriage - it was given to my wife by her father when she was a child.
My second machine was a Eight Ball, obtained that through the Perkiomenville Auction. The third machine was the United Shuffle Alley, circa 1949. I replaced the playfield with a new hardwood deck. The service manual for this machine is hand typed! I sold this machine in November, 2003.
In 2002, I then traded a Gottlieb Atlas (electrical mechanical) machine for a Williams (solid state) Lucky 7, which required extensive circuit board rebuilding (sold November, 2003).
Black Hole was a restoration that I enjoyed playing for quite a while. I sold it in October, 2004. I sold a second Black Hole a year later.
When we relocated from Pennsylvania to Oregon in the summer of 2006, I had to reduce the machines in my collection. I sold my Johnny Mnemonic, White Water, two Flash machines, Eight Ball, and a High Speed. It broke my heart, but it is expensive to move them across the country and we did not have enough room in our temporary housing.
