- El Sphere 1 fue un ordenador personal diseñado en 1975 por Michael Donald Wise (1949–2002), creador y presidente de la empresa Sphere Corporation, ubicada en la ciudad de Bountiful (cerca de Salt Lake City), en el estado de Utah de los EE. UU. Su producción cesó en 1977. El Sphere 1 está considerado como uno de los primeros ordenadores personales. Operaba usando un procesador Motorola 6800 como CPU, una ROM de 1Kb, una RAM de 4Kb ampliables a 64Kb, todo integrado en una carcasa con monitor y teclado que disponía de teclas numéricas y de cursores separadas. Wise dijo que fue el "primer ordenador personal", ya que disponía de monitor, teclado y disquetera en lugar de cinta de papel. Cuando la revista Byte cumplió 5 años, publicó una historia de los equipos informáticos, donde incluyó al Sphere 1 como el primer personal indicando que los microcomputadores anteriores carecían de la interfaz de usuario integrada del Sphere 1.

- The Sphere 1 was a personal computer completed in 1975 by Michael Donald Wise and Monroe Tyler of Sphere Corporation, of Bountiful, Utah. The Sphere 1 featured a Motorola 6800 CPU, onboard ROM, a full-sized CRT monitor, 4 KB of RAM, and a keyboard with a numeric keypad. The Sphere 1 was among the earliest complete all-in-one microcomputers that could be plugged in, turned on, and was fully functional. 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. It is not clear how many systems were sold; production models were sent to computer stores, but the company disappeared shortly thereafter. (en)
- Lo Sphere 1 fu un personal computer messo in commercio nel 1975 da Sphere Corporation, un'azienda produttrice di computer fondata da Michael Donald Wise (1949–2002) a Bountiful, nello Utah (USA). Lo Sphere 1 era basato sulla CPU Motorola 6800, integrava della ROM sulla scheda madre, 4 kB di memoria RAM espandibili a 64 kB, un monitor e una tastiera con un tastierino numerico. Lo Sphere 1 è riconosciuto dalla rivista Byte come primo personal computer nelle sue pubblicazioni commemorative (ogni 5 anni): quello che differenziava lo Sphere 1 dai precedenti microcomputer era che esso includeva il tastierino numerico ed il monitor in un cabinet. Bisogna ricordare che prima di esso vi sono stati altri computer di tipo "personal" ma dalle caratteristiche meno moderne (in particolare, non erano utilizzati microprocessori). (it)
