I have a Gottlieb Freddy Nightmare on Elm Street pinny and a Waterworld machine. The layout of the boards n playfield and everything the way it is under a Gottlieb on these two titles is engineered extremely well. The easy layout on the base of the playfield with fuse layout is a very smart idea i havent seen on any other manufacturers etc. Gottlieb put alot of thought into those designs. If u look under a Freddy pinny, you will see all the smart design features I mentioned etc.
Obviously these are later DMD machines but I was exceptionally happy n surprised at how easy they are to work on and have been absolute hassle free. Perhaps its the earlier Gottliebs that are a pain ?
Also, the Waterworld machine will be getting Leds soon so I will report back on the end results with Leds etc.
