The Sphere 1 was among the earliest complete all-in-one microcomputers that could be plugged in, turned on, and was fully functional.[10] 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. In this respect, it is pre-dated by the 1973 MCM/70, among others, but the Sphere included a full-sized display that these generally lacked. 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 1.
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.[11][12]
It is not clear how many systems were sold; production models were sent to computer stores, but the company disappeared shortly thereafter.

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-l-o-w. Real s-l-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.

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.
