“640K ought to be enough for anybody,” Bill Gates famously once said, referring to RAM in PCs. Or at least he’s rumored to have said—the man himself strenuously denies the attribution and a number of sources who have worked to trace the provenance of the comment have come up short. That said, as this slideshow demonstrates, 640 KB was a stupendous amount of memory for the time. Take a look back at some of the early technologies used for digital data storage—and realize that it would probably take dozens of them to deliver the same capacity as in your average car key.
