Patches and discussion for Ensoniq VFX family

I found a compatible (CR2032) lithium at RadioShack, but I can't tell 
(or get the board out to tell) which of the two connectors is which on 
the board (+ and -).  I tried downloading the .tif schematics from 
the "files" section on here, but all of them seem to be "damaged" 
according to my computer.  The battery connection on the board looks 
like this when looking at it from above:

  *  (     )  *

the space in the middle is for the battery, obviously, but which of 
the two slots are which?  I unfortunately had to ruin the connector 
desoldering the batter, and I was going to try and re-solder a new one 
in with wires just to get it up and running again.

Any help?
