The Sphere I was a personal computer completed in 1975 by Michael Donald Wise and Monroe Tyler of Sphere Corporation, of Bountiful, Utah. The Sphere I featured a Motorola 6800 CPU, onboard ROM, a big 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.

Outside the Brooks Hall site of the show was parked a small van containing Mike Wise and his unique computer from the Sphere Company located in Bountiful, Utah. The one thing we remember about the Sphere was that its BASIC was s-1-o-w. Real s-1-o-w! The Sphere computer was never seen again: it was advertised and a couple were even delivered to computer stores, but very soon Sphere vanished from the face of the earth-a fate shared by many other pioneering computer models.

- The first decade of personal computing. By David H. Ahl, CREATIVE COMPUTING VOL. 10, NO. 11 / NOVEMBER 1984 / PAGE 30,You may think that the Apple II (1977) was the first integrated computer. Not so; the Sphere computer (1975) designed by Mike Wise contained the processor, keyboard, and display all in a case that looked very much like a Hazeltine terminal or TRS-80 Model III.
