The Sphere I was among the earliest microcomputers.[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. 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.[11][12] References1. ^Byte Magazine, Volume 1 Issue 5, January 1976 2. ^[https://www.findagrave.com/memorial/65293456 Michael Donald "Mike" Wise (1949 - 2002)], Find A Grave Memorial 3. ^{{cite web |url=http://www.splor.com/about.html |title=Splore - About:Michael D.

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. 8. ^The Sphere 1., by Early Computers Project, The Sphere Corporation put out a newsletter entitled, "Global News" 9. ^[https://archive.org/stream/byte-magazine-1975-09/1975_09_BYTE_00-01_The_Worlds_Greatest_Toy#page/n95/mode/2up Sphere Advertisement (Page 94-95)], Byte Magazine Volume 00 Number 01, Published September 1975, Internet Archive 10. ^The first decade of personal computing.

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. 11. ^{{cite web|title=Vintage Computer Festival - Featured Speaker|url=http://www.vintage.org/vcf99/mw-bio.htm|accessdate=2011-12-13|deadurl=yes|archiveurl=https://web.archive.org/web/20120206025749/http://www.vintage.org/vcf99/mw-bio.htm|archivedate=2012-02-06|df=}} 12. ^Vintage Sphere Computer at the "Bugbook Historical Microcomputer Museum", 2013-03-10 External links
