If you search for "Blaauw 360-67" you'll get several hits similar to the following from Wikipedia:
[Gerritt Blaauw] designed a revolutionary address translation system, the "Blaauw Box", which was removed from the original S/360 design, but was later used in IBM's proposal to Project MAC, and incorporated in the important IBM System/360-67. From some things I'd been told by Mike Alexander and Scott Gerstenberger the very last bit above about the "Blaauw box" being incorporated in the IBM S/360-67 didn't seem quite right. |
