SEGA is famous for its arcade system boards like the LINDBERGH and the NAOMI. These are the computer systems that run arcade games.

If SEGA's latest trademark filings are indication, the company might be ready to roll out new arcade boards.

Three trademarks popped up for use with video game software, arcade game boards, stand alone game machines and arcade game machines with built-in screens. The trademarks appear to be linked and are for "RINGWIDE," "RINGEDGE" and a logo with rings.
