In 1986-7, the Museum acquired 27 computers, including a CDC 1604, MIT AI Lab CADR, MIT Lincoln Lab LINC, Prime Computer Model 300, Research Machines 380Z, and a Xerox Alto II. As part of the development of the Smart Machines gallery, robot collecting was especially active, with robots such as Carnegie Mellon University Robotics Institute's Direct Drive Arm I and Pluto Rover, GM Consight-I Project materials, Johns Hopkins University Adaptive Machines Group's Beast, Naval Systems International Sea Rover, and Rehabilitation Institute of Pittsburgh Page Turning Robot. The collections of Subassemblies and Components, Memories, Calculating Devices and Transducers continued to expand as well.
