Correction: the MP parallel processor project cancelled by Cray Research (CI No 759) is not the one code-named Y-MP but a follow-on to that machine – Cray says that the team working on the Y-MP expects to install a complete system at Cray’s Mendota Heights base at year-end, a full-scale prototype of the Cray-3 is expected next year, while a follow-on to the Y-MP is now defined.
