166,725 *NB: For Robotron 2084, my version of MAME (and probably all others) had the default difficulty level set to "3" ("liberal"), not "5"("recommended"), which is the proper setting for this round of the competition. These Williams machines didn't have dip switches, so the only way to change the difficulty is to "advance" through the diagnostic pages (F2 on most versions of MAME) until you reach the settings page where the difficult level can be manually adjusted.
