So i picked up this pin,
its a Gottlieb Duotron 2 player EM
its in good shape over all and the first game ive ever gotten with 3 full wiring diagrams, and all the original documentation including the registration cards.  
it was quite the pain in the butt tho.
when i called the lady said its easy to move and in the garage, she didnt mention that it was still fully assembled and they "lost the keys"
if i knew that I would of brought my drill. i managed to get the back cover off with a screwdriver and disassemble it. but it took a while and ive been hearing about it from my wife ever since.
The pin would only power up when i was there but since it was locked i couldnt even add a credit. so im hopping its just a fuse since they have had it for 15 years and before that it was in a fire hall.
theres only one mark of wear on the play field, otherwise its nice, just needs some maintenance.
havent plugged it in yet since im already in the dog house.

I've always loved the art in this game... congrats!

Great robotic theme on the backglass. Played it when it was new! (Im old).

Turns out the player one credit wire was cut. Fixed it and now it works.  Just needs a bit of cleaning

Hi, great catch !! I remark that you're only 25 ! Happy to see new young members
