Attached are photos, sorry they are all sideways (damn you, iPhone). If some kind soul on this forum could take pity on a full-blown newbie and give me some suggestions on where I might source a key and any other info, I would be most appreciative. After a minute or two the volume of the sound decreases but just keeps repeating until unplugged. When I plug the machine in, it lights up and starts playing a loud, repeating musical sound. The key slot looks like it wants a circular key. I searched your forum and downloaded the 'Pachislo Slot Machine Operating Manual' but of course can't do much without this phantom key. Some kind of projected display over the wheels? A digital display on the left shows 'E-4', an error code? Gaming and some amenities are open 24 hours a day, five six-sided dice. Funny thing is, when I plug it in the three wheels are covered by what must be indicators that there is an error but they don't show up in the photos. They will look for it as they unpack at their new house, but in the meantime I'd like to try to find one and get this beast working again. She told me that it needs to be 'reset' but they can't find the key. Found your forum while searching for info on a slot machine I bought for $50 from a neighbor who is moving.
