Harry writes "In 1986, Apple unveiled one of the most popular Macintoshes ever, the Mac Plus. The company gave the first one (serial number #F4200NUM0001) to Star Trek's creator, Gene Roddenberry. And now this very Mac Plus will go up for auction at a Hollywood collectibles event on October 8th and 9th, complete with a letter of authenticity from Roddenberry's son. The estimated value is only $800-$1200, which seems reasonable enough, given its double historical significance." Any bets on how high the bidding will go?
