MV8-OP1 Clone Installation Instructions
Place the unit face down on a table, and remove all screws from the bottom of the unit. Remove the bottom panel so the unit looks as above.
Remove the screws from the MV8-OP1 card blank panel, and push the panel out from the inside.
Plug the provided ribbon cable into the MV-8800 mainboard, so that one end hangs out of the MV8-OP1 card slot. The ribbon cable is notched, so it should only fit easily in one direction.
Take the MV8-OP1 clone board, and insert the ribbon cable into the board - again, it should only fit in one way. The card then has to be twisted upside down so that the cable folds over itself (that is why the previous cable has a bend). It can be helpful to hold the cable into place as you push the card back all the way into the unit.
After fully inserting the card, it should look like so in the MV-8800. Insert the screws loosely so that it holds into place.
Align the panel for best fit (it has a small amount of wiggle room - but will completely cover the cutout on the MV-8800). It should be as low as possible (in the direction of the red arrow) on the unit. Once you're happy with the positioning, tighten the screws.
Put the bottom panel back onto the unit, and screw it back in! Then start making music!
