Thanks parametric for your kind words!
And you are quite correct to warn about excessive heat when de-soldering and not only because of the risk of lifting lands.
When I removed the original 2032 battery from my DX7 MKI some years ago, I "fried" the isolation diode in the process. It is very difficult to remove these batteries with minimal heat because they act as a large heat sink. Plus, a lot of solder was used to install them directly to the PC board. BTW, a solder sucker is essential.
I had to replace the diode because it was evident by the 5V battery voltage reading on the DX7 when it was powered on, that the diode had become shorted. Obviously, I replaced the battery with a battery holder to avoid ever having to de-solder a 2032 heat sink (battery) again, LOL.
