Reviewer: "tradesman1400" (Akron, Ohio USA)
This book is rather dated now as far as the technical side of it
as well as the 70's outlook on life in general. But, I miss the old outlook, anyway. Aside from all that, it is still a great read.
I believe it to be one of the first science-fiction stories dealing with a computer virus, even an intelligent one. Very tight and doesn't let up. You'll love the dialogue between the AI and the people it deals with. Get this one if you can find it.
