In September 1967 I enrolled in MIT and soon connected with the PDP-1 
system where the ideas in Dennis and van Horn's seminal paper [1966] 
were being implemented. I am fortunate to have learned about 
capabilities before my mind was poisoned with more conventional 
systems.

In September 1972 I left MIT and went to the RISOS group at LLNL, as 
you know. While there I met Norm when he gave a lecture about his 
work on KeyKOS (then Gnosis). Yes we discussed the DCCS, but I think 
the main idea of collapsing indirection chains, and all the writing, 
were yours.

Around September 1976 I left LLNL and went to work with Norm at 
Tymshare, where we built KeyKOS.
