Yeah, that's how I controlled the disk drive; I can't remember why I needed
to do that - seek specific sectors; but I read the IBM manual and figured
it out. That was 1968. The University had just bought an IBM 360/40. Since
I was the only one on campus who knew how to work the thing, I got to be
the Systems Manager. My first paid job in computing.

The year after I wrote my first commercial product using the school's
resources of course. Delivered to customers on a deck of punched cards.
Good times...
