Anyone who has had or worked on a Macintosh Classic knows that it's not IF it will fail, but WHEN and HOW BAD. Watch as I unbox this New Old Stock Compact Macintosh from 1990. Will the analog board be too far gone? Has the battery exploded and eaten through half of the logic board? Find out if this mac is dead, or if it miraculously was spared from it's fate.
