Where would you date C994xxx? I am getting conflicting opinions...one says late '78/early '79, and another says 1980.
What about E489xxx? Mid-80s?
Finally, a bit off-topic but important, any update on David's book pub schedule? I placed my pre-order on Amazon the minute I heard about it being available for pre-order. (Ordered one for home, one for the office!)
