[sdiy] DX7 battery replacement help

[Jason Proctor]

thanks for the help everyone.

i thought i'd just jump in anyway and see how it goes. right now i'm 
disconnecting all the cable runs to the main board, and what a pain 
it is. the actual soldering should be the easy part!

the thing is built like a tank for sure. had it since new in 1986, 
it's been 100% solid.
