Quoted from Jappie:
That's a pretty cool cocktail collection, congratulations! I've been wondering: is the basic structure of all these cabinets the same? Did the manufacturers copy the design from each other? Or are there more differences than meets the eye?
The cabinets are pretty much structured the same way, the International Concepts and Allied leisure machines have the coin mechs in the door, nice and compact, while the Game Plan pins have the coin mechs in the upper part of the cabinet with long chutes to drop the coins to the bottom. They all have the glass as part of the top panel that is easily removed by opening one or two locks in the front and / or back.
The allied leisure has two openings underneath in front and back where you can flip the brackets open to remove the glass. Intl Concepts/Gottlieb and Game Plan have a lock in the back that must be opened with a key, and the glass is lifted from the back and slid toward the back of the machine to unlatch the front. These are sometimes a little tricky to put back on as they have to be perfectly lined up.
I keep all the locks/brackets open.
All of the boards are arranged on the sides of the bottom part of the cabinet and the power supplies are generally on the bottom.
I like the Roy Clark machine because it has chimes. The Game Plans have annoying beeps, Of course, Night Moves has a killer sound system and music/sound effects. There is a bigger woofer and a smaller general speaker in Night Moves, bass is excellent.
Also, the Allied Leisure (At least the older ones) have a fan at the bottom front right of the cabinet. With age, the fan is very noisy.
The main difference is in the score displays. My allied leisure is an older one, 1976 I think, and has two score displays with RED LEDS lights to indicate number of players and ball in play, right in the top front or Apron Area, as well as a credits display and tilt and game over LEDs. Later Allied's have the 4 Player displays. Game Plan has the score displays in the same area, but there are 4 of them, and numeric displays for ball and number of players. The ball in play/number of players/match display is shared and there are lines and boxes to indicate what is in the display. This kind of detracts from the look. It's not very elegant. Lastly, the Night Moves / Caribbean Cruise machines have the display in the center of the playfield. This is a nice idea so you don't have to take your eyes off of the game to see the display information.
