While the book was writed in the 1960s, many of the facts remain true. Computer Organization deals primarily with the nuts and bolts of the hardware and how circuitry works. Difficulties arose when the author talks about long since past data storage punch cards and the old IBM machines. FORTRAN is used as the 'familiar' language for many examples, which becomes slightly confusing to new generation OOP programmers. There's more than likely a better book about Computer Organization utilizing newer concepts, terminology and programming, but this makes for a good read into the history of computers.
