Since I've fallen _way_ behind in reading my email (I'm reading July 2015's messages now), I've just recently read a thread where removing the batteries from VAX 4000-xxx systems was discussed and recommended. Since I didn't get _any_ documentation when I rescued my VAX 4000-200 system, which module(s) contain batteries that I should remove for safety? Or can you recommend the appropriate manual(s) at sites like Bitsavers that I download & study to locate to the batteries to remove before they leak and cause corrosion issues? Hopefully I don't already have a big mess to clean up! Thanks, Bob
