Reminiscences of Project Y and the ACS Project

Lookup NU author(s): Professor Brian RandellORCiD



These reminiscences relate to the period that I spent during 1964-66 first in IBM Research working in Project Y and then in the Systems Development Division in the resulting ACS Project - then-secret projects whose aim was to build a super-computer that would be one hundred times faster than Stretch. My account is based mainly on memory, but also makes use of the small set of files that I had retained afterwards, mainly relating to patent applications. A scanned copy of one of these files, the paper “Dynamic Instruction Scheduling”, that I co-authored with Lynn Conway, Don Rozenberg and Don Senzig in February 1966, is included as Appendix 1. Text of a section on “Interrupts” which was added to the 1969 IBM San José Technical Report version of this paper is given as Appendix 2.
