Ok, so I've plugged in that SDS7 I had since 1986, and it powers on etc but no sound comes 
out.  I pulled all the modules and the card with the battery and it looks like this:

Looks like some corrosion on the battery.  So- Simmons made the battery permanent?
  What is it?

Thanks!

Is there any juice left in the battery? Otherwise changing that would be 
a start at least.
If it's dead, the memory with sounds is gone, but you could always try 
making a new patch from scratch. That ought to work without the 
batteries - right guys? That should give an idea if something else is 
broken. With a basic patch I think you should get sound from the 
analogue part of the SDS-7 anyway since that shouldn't depend on the 
battery.

Not sure if there is juice in the battery or not- I'll have to get an ohmmeter- I'm just 
getting started.

I'm surprised that the thing is soldered right onto the card- I would have thought 
Simmons would have made it easier to change.  Unless they expected the SDS7 to just be 
disposable...

OK, a cheap one works well for those tricks too...

Well, back in the early 80's everyone did this. All synths are designed 
like this and as you say, in a way noone expected them to last more than 
6-8 years maybe which is a normal life expectancy for a battery soldered 
in place.

The battery is a rechargable 3.6V nickel-cadmium cell.

Replace it with a battery of this type :

Good one to have in the archives - thanks!
My SDS-7 toured a lot during the 90's so I guess it's still in a pretty 
good nick as far as the battery goes.
