An arcade system based on the PlayStation, mostly known for being used by almost all of Konami's rhythm games prior to 2005. At least three different variants of the BIOS are known to exist, along with four board variations (Plain, Analog, Digital, and Satellite Terminal).

The name "System 573" comes from goroawase, a form of Japanese wordplay in which numbers are used to stand in for their phonetic reading. "573" can be read "ko - na - mi".
