I thought these were pads for "flying leads".  Since they are not, how 
would they connect to the sockets underneath?  Press-fit?

No, if they aren't flying leads, the board has to be as long as the 
distance from CHARROM to BASIC.  But, for a production board, I am not 
sure press-fit operation is ideal.
