Mr.Do! Finished!

I’ve spent the last day trying to finish my Electrocoin Midi Mr.Do! arcade cabinet.

First up was applying the artwork onto the control panel. Considering that I’ve never done this before I think I made a fairly decent effort of it. Obviously I made a slight error as the bottom left does not quite match the bottom right, but I can live with it 🙂

Control Panel Front

Secondly I rebuilt the control panel, cleaning up the screws, washers, and nuts as I went along. I replaced the leaf buttons as the original ones were damaged. But kept with the same joystick, apart from washing it and applying new microswitches. I did the same with the Player 1 and Player 2 buttons.

Control Panel Back

I then tested out the wiring and made a few minor changes due to simple mistakes, and added a ground onto the control panel for safety.

I had a look at the left coin mech that wasn’t working. It’s missing a credit board, so I’ll leave it as it is. The wiring has been cut all over the place so it was difficult to work out what was going on , so I utilised the 12v that was coming off one of the connectors to get the lights lit up. At least one of the mechs is working ok.

I then cleaned the paint speckles off the left side with a magic eraser and centred the screen on the monitor. I think I’m pretty done with this now. Not perfect, but at a fairly decent standard now. Might have a few games on Mr.Do! this evening 🙂

Well the good news is that after applying a new layer of insulating varnish on the monitor, it appears that it is no longer arcing! I had the monitor powered up for a good 10 minutes or so, and there were no obvious issues.

So I’ve put the monitor back in the cabinet, made a few adjustments, and the picture is looking pretty good!

I’ve also put the smoked glass, and reproduction monitor bezel back on, and it’s starting to take shape:

Mr.Do Nearly Complete

There’s a few things that still need attention:

  • New artwork needs to be applied to the control panel
  • The control panel needs rebuilding – screws need cleaning, buttons need replacing
  • The first coin mech and bulb are not working so that needs attention
  • There are still a few paint marks on the side of the cabinet so they need removing
  • The rubber matting on the bottom of the cab needs replacing
  • MTC9000 arcing

    I’ve been trying to get an MTC9000 monitor working for my Mr.Do cabinet, but have issues with it arcing.

    I’ve removed the monitor and can see that the insulated area around the anode is pretty damaged:

    Anode Damage

    As it’s a pretty sunny day outside I thought I would try and repair this problem using some high voltage insulating varnish. This stuff is pretty nasty, so I wanted to do this in the fresh air with gloves, mask and goggles on.

    Hopefully when this is cured in 24 hrs, my issues with this CRT will be resolved. I hope so, as there is zero screen burn on this monitor.

    Then I just need to get the chassis sorted 🙁

    I’ve been very busy getting the Electrocoin Midi Mr.Do back into shape. The monitor bezel artwork was beyond repair:

    Damaged Bezel

    I had no choice but to remove it all. The glass condition underneath the flaky paint was incredibly good:

    I plan to use a piece of perspex underneath the glass, with some reproduction artwork on, so it will look like the original but will never flake again.

    The coin door and marquee brackets were also stripped down, powder coated, and put back together. They both look really good:

    At the same time the control panel was removed, and powder coated, ready for the reproduction artwork to be applied:
