Arcade 1up - Dig Dug Countercade
=======================================
Did a breakdown, and some testing with the Arcade 1up Dig dug machine.
Its a very minimal build, with 1 new component that is not in the
normal machines.
Retroralph did a breakdown on the pac-man one on youtube, so if you
want to see that as a video reference, it might help.
----------------------------
Parts:
------------------------
1 joystick
2 player buttons for action / pump [1 on left of joystick, 1 on right]
2 player start/credit buttons
1 volume adjustment switch
1 on off switch
cabinet
-----------
1 control panel
1 control panel plexiglass overlay - 2 large screws
1 panel under control panel in front
---------------------------------------------------
1 plain back panel - attached with 4 screws
1 top panel overhanging - to hold in marquee
1 marquee panel
1 front bezel
2 left and right panels
video
------
1 8 inch lcd screen
1 lcd controller cable converter
1 cable for lcd
1 cable for power to lcd
box covering the video board - 2 small screws
game
--------
1 ribbon cable to control panel
1 cable with ground from PCB to video board
1 game pcb
1 power cable
1 multi wire cable to video board
box covering PCB - 2 screws
ALWAYS MAKE SURE POWER IS OFF BEFORE STARTING
===================================================
None of the screws were tightened much
Also, although most of the cables are one way, make a
not of the reversible one, with the red wires, and also
which sides are plugged in. Take pictures if necessary.
Tools need - Philips Screwdriver
- possible smaller sized philips screwdriver
- something to hold the screws
I flipped the machine onto the front for this part
-----------------------
1 - detach power cable from small connector to mini plug on back
2 - Detach 4 screws on back panel
3 - Carefully unplug the mini power cord from the PCB
4 - Remove the 2 side screws from the box over the PCB,
you now have access to it.
============================================================
I stood the machine up for this
5 - Remove the front 2 large screws from the control panel
DO NOT LIFT OUT YET
6 - carefully pull up, and REMOVE the 2 pin cable attached to the
speaker. If you yanked the control panel off, it will probably rip
out the cable.
7 - Detach the large ribbon cable from the control panel,
this will free up the PCB.
8 - Remove the ground screw and then you can detach the larger
ribbon cable (the one with the red wires)
9 - You can also remove the smaller cable with 3 wires on it.
This removes the PCB from the board
======================================================
10 - Remove the 2 small screws from the side of the box on the
back of the LCD
11 - Remove the 2 cables from the back of the lcd converter board.
This gives you access to the video board, if you want to attach
another one for Modding, or a different LVDS adapter.
=========================================================
* To reassamble - just reverse the steps
=========================================================
At this point, theoretically, you could swap in another
control panel, other countercade PCB's, etc.
Or just experiment.
I did the reverse, and tried plugging the Dig Dug PCB, into a full
sized Arcade 1UP, but of course, the video output is not compatible
and just gave a blank screen.
If the settings in the software can be modified to address it, it most
likely would work, but of course, the control panel would have to be
altered with that board too.
