So I'll just say that swapping game makes an S+ machine much more entertaining depending on the mood. I love my Double Diamond Deluxe but sometimes I just want to play something else.
As previously indicated I managed to fix another MPU board and I installed a 5 line Red White and Blue 95% chip on it. I also obtained a set of reels that already had the needed strips so I just had to swap the board and the reels and I was all set. To make up for the payline glass I simply used a wet erase marker on the outside to draw the additional paylines.
I love how modular these systems are. Makes for a lot more fun without buying a bunch of individual slot machines.
PS: The tray knob for my second MPU board is loose...as if its been slightly unscrewed. Any ideas how to tighten it down?
