Video Description

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. As a reminder, I provide a lot of detail throughout the video in the subtitles, so if you're interested, turn on Closed Captions - let me know who can find the @LGR reference ;) WARNING - SPOILER ALERT in the chapter headings below. 0:00 - Introduction 1:55 - The Unboxing begins 5:16 - Breaking the seal 7:10 - Opening the case & checking for damage 8:40 - First power on test 9:00 - Replacing the PRAM battery & second power on test 9:43 - Disassembly & removing the analog board (630-0525 Rev.
