University of Pittsburgh LEARNING RESEARCH AND DEVELOPMENT CENTER August 9, 1977 Dr. Elliott Levinthal AIM User Liaison SUMEX-AIM Computer Project c/o Dept. of Genetics, S047 Stanford University Medical Center Stanford, CA 94305 Dear Dr. Levinthal: Enclosed are two copies of a proposal from James Greeno and me to gain access to SUMEX. As you will note in reading it, we are already able to use a small amount of disk space via Anderson's ACT project. However, we need more disk space than the 50 pages John can spare us, So we are making a separate application as a separate project. If the SUMEX-AIM management is willing to allocate the resources we need through the ACT project without cutting back Anderson's work, this is agreeable to Greeno and me. If you would like to conduct an independent review, then please consider the enclosed as submitted for informal comment, which we will appreciate greatly. Sincerely, Alan M. Lesgold Research Associate Assistant Professor of Psychology AML: pag Enclosures LRDC BLOG.. 3939 O'HARA ST., PITTSBURGH, PA. 152ยข2
