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
