The System 573 is a series of arcade system boards by Konami based on the original PlayStation. The hardware was used primarily for Konami's Bemani series of music video game arcades, most commonly the Dance Dance Revolution series introduced in 1998. The System 573 is available in two variants with analog and digital I/O boards, dubbed the Bemani System 573 Analog and Bemani System 573 Digital respectively, along with a third variant called the System 573 Satellite Terminal which allows for up to 8 cabinets to be networked to a central one.

The name of the board is rooted in Japanese wordplay; each number in Japanese can be read with a number of different names, with Konami's name being one of many possible readings for "five-seven-three."[1]

Technical specifications

Main article: PlayStation technical specifications

The System 573 uses the same system design as the original Sony PlayStation but with a few upgrades. Notably the 573 uses double the work RAM and video RAM and is missing the CD controller from the PlayStation. Also added was an IDE port, RTC with battery backed SRAM, dedicated JAMMA and JVS interfaces, a security cart which could be used to easily add expansion I/O hardware and dual PCMCIA slots although these are only wired up as memory devices and cannot be used for I/O cards.
