40 years ago: Bomb blast damages KU computer center, injures students

From the Lawrence Daily Journal-World for Dec. 12, 1970:

After nearly a week of turmoil on campus, a bomb blast at Kansas University’s Summerfield Hall had injured three students and severely damaged the “computation center” of the university. The three students had suffered cuts, bruises, and eardrum injuries from the blast, but doctors said that it could be weeks before it was known whether their hearing damage was permanent. The blast had occurred about three and a half minutes after a warning call had been phoned in to the dispatch switchboard. The force of the explosion had destroyed an interior concrete block wall, bent the interior metal doorways, and buckled the walls of a staircase. Sheets of computer printouts were flung into tree branches outside, and shrapnel-like fragments had flown across a walkway and smashed into two annex buildings. The $3.5 million GE-635 computer apparently had not been seriously damaged in the blast.
