|System||Capcom Play System 1.5|
Before releasing the CPS2, Capcom released an enhanced version of their CPS system, which had some features that would later be used in the CPS2, such as the Q-Sound chips. The CPS 1.5 boards have four inter-locking PCBs and are contained in gray plastic boxes. They have two batteries on the boards that kill the board when they die. Unlike the CPS2, CPS 1.5 sound ROMs were encrypted using "Kabuki" Z80s.
The CPS1.5 was released in december 1992.
