  1961 Beckman DEXTIR Computer by Bill Degnan - 02/19/2021 23:40
Beckman Instruments, Inc. made a connected industrial research computer system called the DEXTIR, which was designed for to prepare data for computer entry. The model pictured in this photo was installed at the ESSO Research Labs in Baton Rouge, LA in July 1961. Click image for larger view.


Beckman issued a proposal to GM some time after the above photo was taken for an automatic monitoring and control system for the Die Casting Department of the Guide Lamp Division at General Motors. The comptuer that the DEXTIR would feed its data was (I believe) a UNIVAC 1108 computer from the same era. Perhaps also an IBM 704, 709, 7090) Download it here

To my knowledge there is nothing published about this machine. For 1961 it looks pretty sophisticated. Until today I had never heard of the DEXTIR, I wonder what happened to it.
