My goodness, it’s been a while!

Some new additions, some new repairs

Having recently dealt with both the Quadra 950 and the Amiga 2000, I felt eminently qualified. Here is my answer This is my method. There are many like it but this is mine.Continue reading “Expanding on removing corrosion caused by batteries.”
