Vintage Simmons Drums (UK) Users Group

Hi all,
I've just had an SDS9 as gift from my friend.
It has some trobles, so I will repair it in the
next days.
One question: do you know where I can find some
eprom images (binary file) for SDS9?
Obviously I will pay for them... and eventually
share mine, if they works (at this moment the
sampled voices doesn't work).

Kind regards,
Roby
