    1972 Sega Sonar EM submarine game.

    So, pretty rare game, only a few of these even exist.

    Of course it doesn't work (yet) but its pretty clean overall and it seems complete.

    Video of game play.

    Cabinet is in really great original shape. Has a bit of splitting near the top but will get glued and clamped back into position.

    Pretty clean on the inside. That little hot pink, green and yellow submarine will need to be fixed.

    Backless is flaking pretty bad but that's ok. Have a NOS glass for it. Will probably have to remake the instruction decals though. We'll see.

    This will be the most difficult thing to find. The left handle grip was replaced at some point. Any help finding one of these would be VERY appreciated.

    I'm uploading a couple videos to show you how it works.

    Quoted from Langless28:

    Just watched the video and I realized I have no concept of how these worked. Any good writeups on how these types of games functioned to show what they show?

    #14 6 years ago

    Yep, its either a bike or motorcycle from the the early 70's.

    Quoted from TractorDoc:

    Looking forward to what you can/will do with this one.
    I am impressed that you can find these games to begin with, much less a NOS Glass for one. The handle bar covers (both the original and replacement) look like something that would have come off a bicycle of the period. The replacement one with the raised fins perhaps from a motorcycle?
    Keep up the good work!

    #15 6 years ago

    Need a new motor for the bubble mechanism. And a new belt. The old belt literally crumbles to the touch.

    30,000 plays.

    New microswitch. Not sure why there's a leaf switch for turning right but a microswitch for turning left.

    Luckily this .25 plate still had plastic on it. Like new underneath.

    #22 6 years ago

    Check this out. It's mostly working now. Credits up, starts a game, controls and buttons work. No sound yet, replacing some bad caps.

    One of the submarines is still a little sticky.

    #23 6 years ago

    Much better, just needed a good cleaning.

    I've never played a Bally Sub-Pack but it looks pretty similar. Love the glass artwork with sharks all over the place.

    Quoted from LarryB:

    Pacman, isn't this the same as Bally Sub Pack? Or what are the differences?

    #28 6 years ago

    No 8 track, sounds all come from this thingamajig.

    Quoted from seshpilot:

    Killer sounds! Is that based off a chip or 8-track style?

    Cool! But be warned, these things can be a nightmare to get working

    Quoted from Langless28:

    These type of games are actually very cool and interesting. So analog and mechanical. Might keep an eye out for this type/ me gun game.

    #32 6 years ago

    Ready for sand blast then powder coating.

    Replacing this and the other tubes with LEDs so it will stay cool behind the glass.

    Thanks!

    Quoted from PM_Jeremy:

    Excellent write-up as usual @packman

    #39 6 years ago

    A little further along. Speaker grill cleaned right up. Removed the rust and gunk without losing any of the finish.

    Plastic coin reject shoot cleaned up. Got all the rust out of the inside as well.

    LOL, me neither. I discovered it when i bought my Sega Sea Devil.

    Quoted from 30FathomDave:

    Holy shit! I’d never even heard of this game. Looks freakin’ awesome.

    #50 6 years ago

    I could do that but it would take considerably more time I've done it on a few in the past, i'll think about doing it again. Might be easier to just shoot video of the actual work.

    Quoted from RobertWinter:

    I love reading all your restoration threads. Amazing work.
    I have a request. In addition to the before and after pictures, I'd also like to see *what* you do to get the end result of each step. Like what process/cleaners/polishers/tools/etc did you use to clean the buttons and coin chute. Stuff like that.
    More details! And keep these threads coming!

    #51 6 years ago

    LOL!! So true!

    Quoted from rufessor:

    The Oompa Loopas don’t like their pictures taken!!

    #56 6 years ago

    Its actually FORMICA. The art is screen printed directly to the cabinet.

    Quoted from RCA1:

    Is the cabinet painted, or is that some sort of laminate?
    (Awesome work as always!)

    #57 6 years ago

    Used an ultra fine wire wheel/brush. With a fast drill, not a cordless.

    Quoted from PM_Jeremy:

    What process did you use to clean the speaker grill?

    IMG_9970 (resized).jpgIMG_9970 (resized).jpg

    #58 6 years ago

    And to clean the other metal pieces like bolts and plates use this stuff called FLITZ - It ROCKS! Wet sand starting low (600 or so) and ending high (2000).

    IMG_9969 (resized).jpgIMG_9969 (resized).jpg

    #59 6 years ago

    Yeah, its pretty time consuming but i'll try to throw in some more tips and tricks.

    Quoted from RobertWinter:

    I'm not saying you should detail *everything*. I imagine documenting these threads already takes a lot of time and effort. Just a few tidbits/pointers on certain things here and there would be great. It's always nice to learn wherever possible.

    #60 6 years ago

    Bottom of the front cabinet had a large bite out of it. Used the same trick as i did on the JUMBO. Cut a piece of formica from behind one of the plates and re-used it.

    IMG_9977 (resized).jpgIMG_9977 (resized).jpg

    #61 6 years ago

    Also got rid of the ridiculous wheels and put on vinyl adjustable leg levelers. Slides around nicely now.

    #62 6 years ago

    Right side looks way better after a bath. Still going to touch up a few holes near the bottom were an operator stuck a piece of plastic to protect the bottom edge.

    Mailman had a surprise for me today.

    IMG_9965 (resized).jpgIMG_9965 (resized).jpg

    #64 6 years ago

    Mounting the black light LED assemblies in place of the old black light tubes.

    IMG_9974 (resized).jpgIMG_9974 (resized).jpg

    #65 6 years ago

    Ocean floor as clean as its going to get. Just used water, don't want to risk using any chemicals on these. The colors are a bit faded from the black lights but not much can be done about that. Only option would be to hand paint every section with florescent paints. Check out the orange mushroom underwater city.

    Thanks! I'll keep putting them up, until my back gives out anyway

    Quoted from kuelman:

    Much love here I don't always comment or post all the time, But your restorations are some of the best post on this forum.
    I love seeing the restoration and repair threads here.

    #69 6 years ago

    Replaced the spinning bubbler motor. Was 7.5/9.1 RPMs before. I had a 10RPM motor from China on hand - close enough!

    This spins a canister that has random holes poked in it. Inside the canister is a bright light that projects "bubbles" onto the scene below.

    Getting really close, the "NOS" glass turned out to be lightly used unfortunately so its going to need a few touch ups and then sealed.

    #86 5 years ago

    I’m quickly getting to the point where I just want it to work. These EMs are really draining my will to live.

    I’ll get some numbers off of them and hope for the best but I’m open to suggestion on modernizing a bit.

    #88 5 years ago

    Ok. Replaced the Caps but still no sound!! Suggestions?

    Quoted from PM_Jeremy:

    Depending on their value and size of the modern replacement part you may be able to tuck new ones inside the chassis. "Usually" caps like that don't totally fail. They will slowly loose their capacitance but will still work in a circuit with reduced efficiency. If you have totally lost sound the issue may be elsewhere.

    #89 5 years ago

    Only getting a hum.

    #90 5 years ago

    New smaller caps hidden underneath

    Replaced ALL these smaller caps as well.
