Here's a bit of an unusual find. 1975 Allied Leisure Dyn 'O Mite. At first I thought it was an EM.
However, when you open it up....
Circuit boards everywhere! From what I can tell, each board basically replaces a particular function/section of an EM's innards. It came with a stack of schematics, which look a little daunting (although most everything is just TTL ICs). It needs a few obvious repairs along the primary electrical path. Considering that all the boards look clean and that it also came with a spare set of boards, I'm thinking I might get lucky.
The playfield is pretty nice for its age. The backglass is perfect. I simply couldn't pass up this odd machine since it looked to be in fairly good shape--which is surprising considering that there's 12,570 plays on the meter.
