The Sphere I was a personal computer completed in 1975 by Michael Donald Wise of Sphere Corporation, of Bountiful, Utah. The Sphere I featured a Motorola 6800 CPU, onboard ROM, Monitor, 4 KB of RAM, and a keyboard with a numeric keypad. Sphere I. The Sphere I was among the earliest microcomputers. Michael touted it as the first "true PC" because it had a keyboard, a number pad, a monitor, external storage, and did not run on a punch tape. When Byte Magazine did its annual history of the computer, it always included Sphere 1, showing that prior microcomputers lacked the user i/o interface built into the Sphere I.
The Sphere 1 also included a keyboard operated reset feature consisting of two keys wired in series that sent a reset signal to the CPU triggering a Hard reboot. Wise considered this to be the first keyboard activated reset - a predecessor to the now-common Control-Alt-Delete combination.
Famous quotes containing the word sphere:
“Men are rewarded for learning the practice of violence in virtually any sphere of activity by money, admiration, recognition, respect, and the genuflection of others honoring their sacred and proven masculinity. In male culture, police are heroic and so are outlaws; males who enforce standards are heroic and so are those who violate them.”
—Andrea Dworkin (b. 1946)
