Legacy

ACS never made it out of the laboratory; I suppose it was too big and expensive, but for me it was probably the most exciting project I have ever been involved in. In reflecting on this, I believe that what made it particularly exciting was that we were a small team, mostly hand-picked by Jack Bertram, and we pioneered every aspect of the project....

My only regret about ACS is that unlike compiler ideas, we did not take the time to publish our ideas on hardware so others could build on them.

Further work was done at IBM in the 1970s on superscalar S/370s, but few, if any, public documents exist.
