Turing's Cathedral

I just started "Turing's Cathedral", which looks interesting, but nobody appears to have told George Dyson how a computer works:
Since a 10-bit order code, combined with 10 bits specifying a memory address, returned a string of 40 bits, the result was a chain reaction analogous to the two-for-one fission of neutrons within the core of an atomic bomb.

It's not analogous at all. Computers work fine if their instruction size is larger, or smaller, than the data word size. I hope he does not continue to wax rhapsodic in the rest of the book.
