Deep-pocketed Star Trek and Apple fanatics will battle it out next month in an auction for the first Macintosh Plus—a computer that happened to be owned by Gene Roddenberry. The Mac Plus was the third Mac model, released 2 years after the original, and the first to offer a whole megabyte of RAM. Apple gave the machine to Roddenberry as a gift, Wired reports. It’s expected to fetch $800 to $1,200, less than its original sticker price of $2,600. (More Gene Roddenberry stories.)
