Black Hole up-kicker rarely needs the driver board conversion
Weak up-kicks are much less of a problem on Black Hole than on Haunted House. If the playfield-mounted 2N5879 transistors on Black Hole already have the 4.7k pull-up resistors, the pop bumper driver board conversion for the up-kicker is not needed.
