I beleive its the first edition. Copyright 1991 MIT,
ISBN 0-262-16123-0.

I read it again today, and might have been slightly mistaken as to the
"3030" definition, although there was a "3330". Here's what the book says:

- Page 495, chapter 9.2, "New Challenges in Storage":

"The IBM 3330 Disk Storage (Figure 9.3) christened Merlin during its
development, was announced in June 1970.."

- page 507, chapter "New Challenges in Storage", second paragraph:

"Specifications were negotiated with engineers responsible for small
systems in the company's Boca Raton laborator. By August it was agreed
that the storage unit should contain two spindles, each with a disk
capacity of 30 megabytes. The engineers called it a "30-30". Recognizing
this as the common name of a popular rifle manufactured by the Winchester
Company, Haughton said, "If it's a 30-30, then it must be a Winchester."
In this manner, the first Winchester file and its many descendants were
christened." (footnote 32)

- Page 508, second paragraph:

"The Winchester disk file, announced in March 1973 and first shipped
that November as the IBM 3340 Disk Storage Unit..."

- Footnote 32:

32. K.E. Haughton, 18 September 1969: to file, "History of Winchester File",
undated: "Education and Employment Information." The three engineers who
joined Haughton and Harker in "dreaming up" disk storage configurations
were Dwight Brede, George Santana, and James Sweet. The new manager for
Storage Products was Marty Kelly

All in all, its a DAMN good book, and one of my favorite reads. I
found the earlier book to be not as "interesting", but at least I got
a copy of it ("IBM's Early Computers") off eBay after 3 years of looking..
