Abstract :
At the Last Fall Joint a year ago I took in the session on Historical Perspectives, and baited panelist Walter Bauer by suggesting that the invention of interrupts was one of the greatest disasters in the history of computer development. (But then he had just piqued me by saying that our present software difficulties are not going to get any better any time soon, and that nothing we computer architects can do will help much.) I´d like to pursue this subject a little further in these pages and try to drag some more of you into the debate (on my side, of course).
