Versions of DCS

• DCS ROM-based mono: The first version of DCS used an Analog Devices ADSP2105 DSP (clocked at 10 MHz) and a DMA-driven DAC, outputting in mono. This was used for the majority of Williams and Midway's pinball games (starting with 1993's Indiana Jones: The Pinball Adventure), as well as Midway's video games, up until the late 1990s.
  • DCS-95: This was a revised version of the original DCS System, used for Williams and Midway's WPC-95 pinball system.
  • The pinball game, The Twilight Zone, was originally supposed to use the DCS System, but because the DCS board was still in development at the time, all of the music and sounds for this game were reprogrammed for the Yamaha YM2151 / Harris CVSD sound board.
• DCS2 ROM-based stereo: This version used the ADSP2104 DSP and two DMA-driven DACs, outputting in stereo. This was used in Midway's Zeus-based hardware, and in the short-lived Pinball 2000 platform.
• DCS2 RAM-based stereo: This version used the ADSP2115 DSP and two DMA-driven DACs, outputting in stereo. This was used in Midway's 3DFX-based hardware (NFL Blitz, etc.). This system would be adopted by Atari Games, following their acquisition by WMS Industries.
• DCS2 RAM-based multi-channel: This version used the ADSP2181 DSP and up to six DMA-driven DACs, outputting in multichannel sound.
