Regarding the Winchester code name, I've argued
about this with Clem
before. Clem claims that the code name refers to various advances in
disk technology first released in the 3330's disk packs. Wikipedia and
my own memory agree with you that Winchester referred to the 3340.
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.
