FOM: Cellular Automata: Computation vrs simulation

[Martin Davis]

John T. Baldwin has properly emphasized the importance of I/O conventions 
in discussions of universality.

In this connection, I'd like to mention two old papers of mine:

``A Note on Universal Turing Machines,'' in Automata Studies, C.E. Shannon 
and J. McCarthy, editors, Annals of Mathematics Studies, Princeton 
University Press, 1956.

``The Definition of Universal Turing Machine,''  Proceedings of the
American Mathematical Society, vol.8(1957), pp. 1125-1126.
