Williams Bubbles Boardset

Compatible Games: Stargate, Robotron, Joust and Splat!

The Bubbles boardset is unique as it has additional CMOS RAM on the CPU board and a different pinout between the CPU and ROM boards, therefore these boards cannot be mixed with other games. The earlier games of Stargate, Robotron, Joust and Splat! will run on this board as they will ignore the extra CMOS RAM.

Note that Splat! uses Special Chip 2 on the ROM board.
