Look for a RANDOM function for the opening phase of play. My Novag 'Ruby' has a nice function that allows you to set three different levels of random play in the opening stages. This allows for a surprisingly large variation of opening play from the computer, or at least the Ruby does. Computers seem to look at the number of times a given opening was played based on it's database of opening moves. So it tends to play the most popular moves because of a numeric value associated with that particular move. The higher the value the more often that move is played. This is what the software BookUp does. It allows you to import .PGN games into it's database for example, and then displays each candidate move with an associated numeric value based on the number of times that move was played. As you add more games the numeric values change and some opening may become more popular as a result. For chess computers, the only way to modify it's opening behavior is with a RANDOM function. As stated, these databases generally reside in a ROM chip which cannot be modified.
