OK, here's today's "gem".
Why were the early hard-drives called "Winchesters"? Well, the preferred version is that the first device IBM produced using this technology had two platters, each with a capacity of 30 MB. The product was called the "3030", and by a kind stroke of fate this was also the name of an early lever-action rifle manufactured by Oliver Winchester (subsequently famous for the Model 73 that helped win the Wild West).
Less romantic chroniclers will point out that IBM happened to have a factory in the New Hampshire town of Winchester.
