Vintage Synth Repair

I've got a Jupiter 6 (not mine) on my bench for a battery replacement (the 
battery was dead, so the volatile memory held nothing).  The owner thinks 
that the factory patches need to be played back into the Jupiter via 
cassette afterwards (a la Prophet 5).  Is this true?  If so, where can this 
tape be found or downloaded?

The Jupiter 6 uses a CR-1/3N battery with tabs.  These seem to be a bit 
difficult to find, but I found someone who has the $20K machine to weld 
tabs onto regular CR-1/3 batteries, which are quite common.  It 
is:  Electronic Supply, 425.774.5534, speak with Don.  His pricing is fair.

The "Batteries Plus" chain seems to have that equipment as well.  Though if it 
were me doing the repair,  I'd be inclined to solder in a holder and not have 
the tabs welded on to the battery.  That's usually what I did with stuff that 
used the more common coin cells...

First, thanks for all the answers re the tapes.  The primary question was 
whether there were such things for the Jupiter.  Now knowing there were, I 
did find them as wav files quickly via Google.  Here's the 
link:  http://www.sid6581.net/synths/

Re the battery, I did look into installing a socket and coin 
battery.  Given the form factor, what would fit would be a socket (Keystone 
3000) which holds a CR1216 or CR1220 battery.  These are rated at 25-35 
mAh, vs the 165 mAh that the original CR-1/3N is rated at.  I was concerned 
that the result would be short battery life.  Changing a coin cell battery 
wouldn't be difficult in the Jupiter, but reloading the presets is a hassle 
for owners.

www.digikey.com or any electronics place can sell you a 3.6v lithium
battery which I think is what's in the JP-6.   Have a look at it.  Replace
with care, but the physical format doesn't have to be exact (just the
voltage and type).
