Here is some trivia about Vector from my days in the Bally Lab,
Designed by my good friend Greg Kmiec, Vector was so packed with targets and features I coined the phrase, 'Vector Syndrome' to describe games with so many objects on the playfield there was physically no room for the ball to roll. Bally wanted to clear out the parts warehouse so the designers were given freedom to throw anything and everything they could think of on the playfield.
Enjoy!
