I had no idea what was lurking below the shielding
Yikes.. That's a surprise
Hadn't expected that
What is worse is there is a battery
also in the A501 RAM expansion
Lets hope I can clean this mess up
First I need to remove the battery
Don't try this yourself but all I do
is very very gently rock the battery
back and forth till it snaps off
I have seen much much worse
OK Vinegar and Baking Soda
First to clean and second to neautralise
The picture I came to originally take
First pass at cleaning
Second pass at cleaning
Looks fine
Fingers crossed. Will leave over night
Dreadful little things
Need to give the whole board a clean
The A501 looks a lot worse
Revision 8A
Pass 3 on the cleaning and time to
leave the board and clean the rest tomorrow
