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:
“Prayer is the fair and radiant daughter of all the human virtues, the arch connecting heaven and earth, the sweet companion that is alike the lion and the dove; and prayer will give you the key of heaven. As pure and as bold as innocence, as strong as all things are that are entire and single, this fair and invincible queen rests on the material world; she has taken possession of it; for, like the sun, she casts about it a sphere of light.”
—Honoré De Balzac (1799–1850)
