    Question Mv1fzs missing chip?

    So I currently own two boards both with issues but the board in question seems to have crashing issues on a few banana cart games example being kof98, not going to go to deep into that issue as im waiting on a real kof98 to come in to determine if its a banana cart issue not a board problem.

    I decided in the mean time to take a look at the board and see if anything was amiss and well it looks like u14 the ls259 motorola chip is unpopulated. Ill be honest these things are a touch over my head so I do not have the slightest clue what it is supposed to do. So my question for all of you is

    A: what is this missing chip for
    B: Is it normal for this to be unpopulated

    All the pictures ive seen of this board have the slot filled so I assume that it's supposed to be there, if so I maybe the cause of my problems? I know its a super cheap part but I'd rather not add something that isnt supposed to be on this board.

    Here is a picture of what Im talking about

    I don't know specifically what that chip does for the MVS but it's an 8 bit addressable latch. Most likely it does serial to parallel conversions.
