Vintage Simmons Drums (UK) Users Group

Isn´t there any switch for selecting which eprom to read from ?

Alternatively, maybe the analog section is bypassed and its programming features are used to change eprom.

  Subject: [Simmons Drums] Questions on four-prommed SDS7 cards


  Hi,

  Does anybody know what the four-prommed SDS7 cards are used for? Are 
  the sounds selectable like on a Simmons SDS1000, or are they parts of 
  sounds on separate chips like on rival machines such as the LinnDrum, 
  Oberheim DMX, or Sequential Circuits Drumtraks. I found a Simmons SDS7 
  tom card on eBay today and just wondered that. I know that it has 
  the "Townhouse Tom", "Gated Tom", "Conga 1", and "Conga 2" EPROMS 
  installed on an expansion card that is mounted where the single EPROM 
  goes on a digital-analog SDS7 card. The expansion board is not 
  something made or installed by a third-party user because it 
  said "Simmons Group Centre" on the expander board. I have not seen this 
  before. I have only seen the digital-analog card that holds one EPROM 
  and the digital card that holds two EPROMs. Can anyone tell me what the 
  four-prom cards are for?

  Thanks for your help

  Dean Rumsey
