And you believe anything in Wikipedia? If so, I have a bridge to sell you! :-)
But, in this case, it's correct. According to "IBM's 360 and Early 370
Computers" (Pugh, Johnson and Palmer - a very good book, BTW), pg. 507, the
first Winchester was the 3340. The confusion comes from the fact that it had
two spindles, each of 30MB capacity, making it a so-called "30-30" system -
that being the name of Winchester's rifle.
