First talking Stern game, using the VSU-100 speech board. There are two versions of the ball serve mechanism pictured in this listing. One game with serial number 598 shows the kicking solenoid mounted above the playfield and under the card holder. Another game with serial number 6324 shows the solenoid is mounted under the playfield. We do not yet know when in the production run this change occurred, or why.
