Group of three circa 1960s personal analog computers in brown carrying cases, manufactured by Pastoriza Electronics in Boston, with each case containing a "Control Unit" plus other modules, marked "Integrate" (5), "Multiply" (5), and "Add" (1). In overall very good condition, with adhesive residue inside the cases. Accompanied by four unrelated vintage computer boards and a catalog for The Computer Museum Store. The Pastoriza Personal Analog computer was originally designed in 1962-63 to be used by students at the Case Institute of Technology. The modular units allowed students to configure the computer to their own preference. Pastoriza Research was bought out by Analog Devices, Inc. in 1969.
