I'm not sure if the date might be significant to anybody, but the first
publication on this topic was an LLNL report:
J. E. Donnelley, "DCAS" - A Distributed Capability Access System, Lawrence
Livermore Laboratory Report UCID-16903, August 1975.
that was substantively identical to the later DCCS publication:
J. E. Donnelley, A Distributed Capability Computing System, Proceedings of
the Third International Conference on Computer Communication, August 1976,
Since that first LLL report was my first publication I'm sure it took me
some months to get it published. When did you leave LLNL to go work for
Timeshare Charlie? Wasn't it in about that time frame (1975)? I know you
and I certainly discussed the DCCS (e.g. with regard to the problems
passing some RATS capabilities, like file capabilities, that couldn't be
emulated with Slave capabilities). Was that discussion after you left
LLNL? I'm a little surprised you weren't a co-author on the DCCS paper.
