Digibarn Events: Ken Sumrall's visit and Cray 1 securing project
(Oct 15, 2006)

We would like to thank Ken Sumrall, who works on projects at the Computer History Museum, for coming to the Digibarn in October 2006 and making it possible for three of the transformers at the base of our Cray 1 supercomputer to be bolted to the processor tower as an securing measure in case of earthquakes.
