I didn't actually work there; I knew a lot of the folks from the perspective of an IT industry analyst both during and after a lot of the work there. I certainly saw some level of integration with things like Dtrace (how couldn't you) but when you were a systems company, it's probably the case that software folks couldn't really just divorce themselves from hardware.
The low-level software work at Data General where I was prior to the analyst biz was certainly integrated to a certain degree--read Soul of a New Machine if you haven't. The software folks for the minis were also mostly in the same same location. As things migrated to Unix, most of that team was in RTP and it's probably fair to say that there was less integration though probably wasn't something I thought about a lot of the time. Hardware stayed in Massachusetts.
