        I asked this question a few months ago a got some useful replys, I
however am still stuck,

        The plan for the cartridge port is this:
                I wish to read data from a video digister in to the computer
through the port, (The printer port is in use for something else) I understand
that the port should not be loaded with any data unless the rom select line is
pulled low, The question is this,
        How do I do it?    My C is not very good but I can understand it, any
help would be gratefully received, example even better,

Dave Johnson.
