Back in the late nineties, I was randomly speaking to a person at a presentation I was attending and mentioned that I liked to refurbish older computers and give them to people who couldn't afford them. He asked for my number and a week or so later called and asked if I wanted a few Macs. A "few" ended up being 3-4 carloads. In those days, I had at least 3, sometimes many more, examples of every Mac made excluding the rare ones. Wish I still had that collection today. They were mostly all in like new condition with no yellowing whatsoever.
