Hey guys...I have one opto error on my Capcom Airborne. Decided to dive into it today, went to replace the opto receiver and it looks to be the wrong size. This is a Williams opto receiver, which I read is what to use as a replacement. Here is a pic of the old and new opto board side by side, and I did a quick install just to show how it didn't line up with the hole in the scoop.

any idea's? not too sure if I want to put a drill on that board.

ok....looks like its going to be the drill...added another picture of the other side of the board. That baby is nasty.

real quick...based on the picture above, should the negative go to the side marked "A" of the new board? C on the old to K on the new?

Thanks for the replies
