Technology Square
From Computer History Wiki
Building at MIT housing Project MAC, which later split into the AI Lab and the Laboratory for Computer Science (including the Dynamic Modeling, Mathlab, and Macsyma Consortium groups).
Layout
Later on, around the outer walls where CTSS/Multics machines used to be were turned into enclosed offices; the remainder of the space was use to hold the MIT-MC KL10 ITS machine. The MIT-XX DECSYSTEM-20 TOPS-20 machine was installed where the 1401 used to be. The MIT-DM KA10 ITS machine was between the DM PDP-6 and the MIT-ML KA10 ITS machine, and also along the outer wall behind the PDP-6.
As the other end, the offices 919-922 were done away with, and that all became open raised floor.
