Plain is a private collector in California, with what he describes as the world's largest collection of rareApple prototypes by a private collector.
Plain even turned his collection into profit by selling the items on eBay. In March, Plain listed a rare Lisa 2 prototype on eBay for just under $100,000: however, it caught the attention of Apple's lawyers and has since been removed.
But Plain will continue adding to his collection and hopes some of the devices end up in a museum one day.
