The Madonna
has a good bit of space inside which I liked. The board on the left
is held in place by a set of metal runners that will take a board
19.5" x 14.75" x .375" I made up the platform to have
a place to rest other PCBs
The marquee
light and speakers have their own door that you can access by taking
out 3 allen screws.
The Coin door
opens, and the other two panels on the front come off, so you can
get to pretty much everything with ease. The coin box (also metal)
goes in the lower right.
