    EZTOPS

    I got a quote to make the dome exact size for $1400 plus shipping. Being a custom size they would have to make a mold.

    So, i took a closer look and figured out that it would still work if i made the dome slightly shorter (about 3/4 of an inch).
    That way i could use a pre-formed size of 29" which only cost $300 shipped.

    Really glad to see this resto active again! Good luck, and thanks for documenting it!

    #103 4 years ago

    Crazy that someone thought up all of this....than put it all together to produce to the masses. Ingenuity!

    #104 4 years ago

    Would love to try playing this game! Wanna earn that win bell!

    #105 4 years ago

    Everything is pretty much disassembled now.

    Found some major rust underneath.

    The rest is in great shape luckily. Just needs a good cleaning.

    The indentations on the front bevel out a little on the back.

    Crusty switch.

    IMG_2705 (resized).jpg

    #115 4 years ago

    More switches, look familiar?

    IMG_2703 (resized).jpg

    #116 4 years ago

    Screen printed plexiglass, a little warped from the lamps underneath so i'll try to flatten them out before putting them back in.

    One of the cables that controls the elephants trunk. Basically a bike brake cable.

    OK, so after pulling this thing apart i've discovered a few things.

    The game never had a timer on it. This thing was rigged together and installed by an operator at some point.

    #119 4 years ago

    And i'm pretty sure i know why.

    After JUMBO lets the ball go it eventually rolls to the bottom of the bowl landing on a switch.

    The switch at the bottom of the game is triggered and and tells the game to turn off the vacuum and the tape player.

    The Styrofoam ball is VERY light so that it can fly through the air.

    The ball is so light that its NOT pushing the switch down to tell the game to end.

    So......

    The operator built this home made timing unit and bypassed the switch all together.

    Following the wires back through the harness they go to the Relay that has a piece of paper jammed inside it.
    The wires also go back to the power supply which was cut.

    The operator went to all the trouble of building this timer thingamajig INSTEAD of cleaning or replacing ONE SWITCH.

    Glad to see progress is being made!

    #121 4 years ago

    These old Sega machines really are amazing, unique, and cool. This particular one is probably in my mind one of the most incredible things ever!

    #122 4 years ago

    I don't understand. Was the reason the ball wouldn't trigger the switch at the bottom of the bowl because the switch was faulty?

    Quoted from dmbjunky:

    The switch works fine if you gently tap it with your finger but the ball is too light to push it down far enough. I need to either clean the switch so it doesn't stick as much or replace it with something much more sensitive.

    #124 4 years ago

    Flags are drawn. Look how faded the originals were.

    Just need to flip them to make folding decals.

    Fun fact: Japanese flag took 4.7 seconds to draw. British flag took 10 minutes

    It's great to see you have some schematics

    Quoted from PACMAN:

    Could you add some weight to the switch arm to make it trip easier?
    I'm thinking of a small fishing weight- kinda cheesy, but might work.
    (Clean it first of course)

    I agree! Its fun to pull it all apart to see how all the intricate parts work together to create the magic.

    Yeah, its nice. Not so lucky on having them for Killer Shark. Had to blow up low rez files for that one and use a magnifying glass.

    Hmmm. Its worth a shot, as long as its not too heavy to come back up and reset. The idea i was kicking around was to install a really long switch with the end just barely sticking up so it wouldn't need to travel so far down.

    #132 4 years ago

    Parts are cleaning up nicely.

    The vacuum pieces just needed a bit of cleaning.
    Also hit them with a light layer of auto clear to prevent them from oxidizing down the road.

    Nice and fresh, ready to reinstall.

    #134 4 years ago

    Wooden board sanded and lighted clear coated.
    Power supply repainted with heat resistant satin black.
    Wire harness cleaned up.
    Plastic covers looks new.
    Relays cleaned.
    Switches cleaned.

    Going to swap the test switch button with one that's not as nice as i want to use the nice one for the outside.

    Have to check a few wires and put some metal back on still.

    And lastly, i need to replace a fuse - ran out so i need to get some more.

    This is the BUZZER that goes off when you win. I'm going to open it up and take a pic of the inside.

    Coin chutes sandblasted, ready for hammered grey paint job. Which is kind of weird as there are no other parts with this finish.

    I tried to clean the beach ball with a few different things but that turned out to be disastrous.

    Its pretty much trashed.

    But that's OK. I found a replacement.

    A polystyrene styrofoam ball.

    The 1 1/2 inch radius is a bit smaller but it would work. I found a 40MM version from China too that should be pretty spot on.
