Not sure if this guy is still with us, but wanted to read "Confessions of a Hearing-Impaired Engineer", if anyone has a copy. BTW, "Where Wizards Stay up Late" is an entertaining book about the origins of the ARPAnet. It even has some of the first (hand-drawn, natch) network diagrams... Apparently, nuclear holocaust considerations did not really play much of a part in ARPAnet's genesis, despite folklore to the contrary. Withstand a nuclear war was not a design consideration (for most of the key players); any such properties were side effects of the real design considerations and decisions. -- "That is not dead which can eternal lie, and with strange aeons even death may die." - H.P.
