This Day in Computer History
Thomas Edison was granted a patent on his two-element vacuum tube.
Intel released the first single-chip CPU in history, as well as the first commercially available microprocessor, the Intel 4004. The chip, designed by Federico Faggin and Marcian “Ted" Hoff, and Masatoshi Shima, was initially developed for Japanese calculator manufacturer Busicom. It ran at a clockspeed of 108 KHz and featured a 4-bit bus. In conjunction with Intel's RAM chips, Intel's 4004 chip will revolutionize the computer industry by beginning the miniaturization of consumer electronics. Price: $200
At the University of Michigan in Ann Arbor, Michigan, a graduate assistant Nicklaus Suino was injured when a mail bomb addressed to a professor and sent from the Unabomber detonates. In all, the domestic terrorist known as the Unabomber sent sixteen bombs, injuring twenty-three people in protest of “the erosion of human freedom necessitated by modern technologies requiring large-scale organization."
At Lehigh University in Pennsylvania, the first virus that caused directly damaged infected computers' data was first discovered. The virus, later dubbed "The Lehigh Virus" affected the COMMAND.COM file of disks formatted for MS-DOS by overwriting the end of the file's stack space. Each time the disk accessed the COMMAND.COM file, usually upon booting, the virus would add another iteration of itself to the file. When the file contained four copies, the virus would overwrite the disk's boot and FAT sectors with data transferred from the affected computer's BIOS. The virus was contained, largely due to its ineffective design. With each infected disk creating only a maximum of four duplicated, it simply failed to "survive" long enough to be unwittingly passed off-campus. In addition, the virus was easily prevented by setting COMMAND.COM as a read-only file.
Hayes Microcomputer Products, one of the nation's largest manufacturer of computer modems, filed in court for Chapter 11 Bankruptcy protection from which it won't emerge until April 1996. During the course of its reorganization, it would struggle against acquisition by both Diamond Multimedia and US Robotics.
Christopher Pile became the first person in history to be sentenced to prison for writing and distributing a computer virus. He was sentenced to eighteen months in jail. Online he was known by the handle “Black Baron".
