    • Norwegian Wood: Neo Geo Cabinet Refresh

      So I posted this up in the 'Recent Purchases' thread recently and plan to share my progress here.



      The cab is 'complete' to the best of my knowledge - the seller apparently received numerous offers to part out the NeoGeo 2-slot and/or the monitor but fortunately turned them down.
      It did come with an OG Xbox installed which was a nice addition.

      These cabs were built up in Trondheim, Norway by a company called Lars Berg AS, hence the LB on the speaker grill. Their same design is used in generic Jamma cabs as well as branded Neo Geo cabs.
      As things are already 80% there, I am planning to complete the Neo Geo theme to look like this:



      I am not planning on preforming any miracles - there is some minor cosmetic damage here and there, but it falls more into 'patina' than 'eyesore' territory.
      I'll be happy if I can get things fully functional and consider anything else as bonus.

      Here are the pics from the ad:



      First task is to get the Neo Geo MV-2F back up and running. The previous owner only made use of the Xbox it seems.
      Then its time to take a closer look at the monitor and see what sort of maintenance is required. Never touched an arcade CRT before, so that is my biggest concern.
    • So here are two pics of the Jamma harness:



      Couple things going on here... but first I'll mention again that this cab was wired for MVS Jamma.

      The Xbox that was installed used an Xbox to Jamma PCB - that could well explain the scorch marks on the resistor attached to pins 10/L.
      As this cab is mono only, Speaker Left and Speaker Right are tied together with a resistor on each output. No idea what was like on the Xbox unit, but clearly wasn't healthy.

      Probably also explains the cut ground wires on pins 27/28, Ae/Af. Guess those caused issues, were cut and bundled up front.
      Of course that means that the giant solder mass on Gnd, +5v etc is probably factory. Kind of odd as the rest of the cab is neatly organised.

      Finally Game Select Up on pin 26 was cut and relocated to pin 11 for some reason. Its just twisted on and secured with the masking tape you see there...

      Anyway... I have reattached the Game Select Up to pin 26. Pretty rough looking, but should be functional.
    • Up next: Cleaning the 2-slot Neo Geo unit. With the latches undone, the whole control panel slides out on rails. The MV-2F is mounted beneath.



      Pulled the PCB and turns out to be in amazing condition - this pic is before I even got as far as dusting.



      Some minor improvements. Leaking battery neutralised with white vinegar, and swapped out for a coin cell. Cart slots were already very clean. Added in Unibios v4.0



      And we're in business. I've managed to adjust the vertical distortion via pots mounted under the screen, but I guess i need to access the width coil for horizontal.

      Looks like you didn't disable the charging circuit. Alternatively, you could swap the coin cell for a rechargeable one.

      Anyway, nice cab! I always regret not picking up a Finnish Neo cab. They were manufactured in Japan, but rebranded here in Finland.
    • Got to work on the control panel this week. Really happy with how it turned out!



      Progress shots:


      New CPO from Arcadeoverlays, and new hardware from ArcadeWorldUK.
      Arcadeoverlays really came through in helping to fit their Neo Geo artwork to my rather non-standard panel.

      For hardware I went with IL Eurosticks and Suzo Happ Classic buttons with Cherry switches.
      Luckily the IL sticks fit the 80x50mm joystick holes on the panel. Just not super easy to centre them.
      I also had to re-crimp the spade connectors on the harness. Previous buttons had half sized spades that these Cherry switches do not.
      End result is a bit of a mixed bag... but that is well with in keeping with the overall style of the build :P

      Nice job but little bit odd button setup methinks.
      I'm still not sure if this is a 3 to 4 button conversion, or if the panel was cut with the button placement template applied back to front...
      If you look at the control panel of the 'stock' Big Red, it looks to have the same layout... B2,3&4 are not in a straight line:



      Maybe I got the offcut panel X/

      Neato looking cabinet indeed.


      :D
    • Still work in progress:



      Monitor is out for service. Burn in is quite apparent with the contrast screen removed. Looks like Fatal Fury - you can make out the life bars and round winner circles pretty clearly. The coin door had taken a beating - the whole panel was bent inwards slightly. Once I straightened things back out I found that also fixed the entire drawer Everything slides in and out smoothly now :thumbup:

      Not too much left to do I hope! Has anyone replaced their contrast screens before? Wondering what sort of tempered glass would work...

      Beautiful work.
      You're going to have the nicest cabinet in Norway.
      If I ever get up there, I'd love to play on this thing, it's beyond rad.
      I hear you guys got Salmon vodka out there.
