Any chance you could document (for history) what the aspect was, and why he did it the way he did? Actually, there is this thing called the 'IEEE Annals of the History of Computing' journal, and they have a special category called 'Anecdotes', where people tell the history of things they were involved in. They don't go through the whole peer review process, so there's a lot less hassle to writing something for that. I just did one on token rings at MIT. It's a good way to capture all this stuff that is of historical interest, but not otherwise documented. Maybe he could be convinved to do one on 'The Design of the KL-10'? Noel
