I knew him well. He was my boss and my neighbor in the early eighties in Mainz, Germany. Like all great men, he had his faults, but he played his role well at CENTCOM and the country was well served by his leadership.
He bought an early PC, an Apple II, and I spent an entire weekend with him helping him getting it set up and then playing with it. I was teacher, he was student - the only time that those roles were reversed. Our wives were not happy as they had other plans for us that weekend.
My heartfelt sympathies on your loss. I only knew OF him and this breaks my heart. For those that were fortunate to know him personally, this is much much harder.
