The problem is that there will always be a finite supply of parts available which makes each liberation VERY important. Every machine that goes to the crusher today means fewer repair parts for the future, which is why I never pass up any machine that comes my way. I remember reading in the vintage video game community that certain parts of the Mattel Intellivision system are becoming extremely difficult to find. Eventually we'll all end up with a bunch of dead vintage Macs with not enough repair parts to go around.
