The PowerBook G3 is a line of laptop Macintosh computers produced by Apple Computer between 1997 and 2001. It was the first laptop to use the PowerPC G3 (PPC740/750) series of microprocessors. It was succeeded by the Titanium PowerBook G4 line in 2001, which used the PowerPC G4 (PPC74xx) series of microprocessors.
The first Macintosh PowerBook G3, code-named "Kanga," was introduced in November 1997. At the time of its introduction, the PowerBook G3 was advertised as the fastest notebook computer available (a title formerly held by its predecessor, the 240 MHz PPC-603ev-based PowerBook 3400c). This model was based on the PowerBook 3400c, and was unofficially known as the PowerBook 3500. It used the same case as the 3400c, and a very similar motherboard. The motherboard was upclocked from 40 MHz to 50 MHz, resulting in some incompatibility with older 3400 RAM modules. Other changes to the motherboard included doubling the on-board RAM from 16 MB to 32 MB, and a faster version of the on-board Chips and Technologies graphics controller. The G3 made the Kanga more than twice as fast as a 3400c, and the improved graphics controller allowed it to refresh the screen 74 percent faster.
Doctor or The Doctor may refer to:
The First Doctor is the initial incarnation of the Doctor, the protagonist of the BBC science fiction television series Doctor Who. He was portrayed by the actor William Hartnell from 1963 to 1966. Hartnell reprised the role once, in the tenth anniversary story The Three Doctors (1973), although due to his failing health the story was written so he would not have to appear very extensively.
Within the series' narrative, the Doctor is a centuries-old alien Time Lord from the planet Gallifrey who travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body; in doing so, his physical appearance and personality change. Hartnell's Doctor is the Doctor's "original" form. The regeneration plot device was introduced when Hartnell needed to leave the series, and consequently has extended the life of the show for many years.
His original companions were his granddaughter Susan (Carole Ann Ford) and her schoolteachers Ian Chesterton (William Russell) and Barbara Wright (Jacqueline Hill). Hartnell's version of the Doctor was also the basis for the character played by the actor Peter Cushing in the 1965 and 1966 Dr. Who films, which do not share a continuity with the television series.
Dr. Who is a character based on the BBC science-fiction television series Doctor Who. Although based on the Doctor appearing in the TV series, the film version of the character is fundamentally different.
The character, portrayed by the actor Peter Cushing, appeared in two films made by AARU Productions: Dr. Who and the Daleks (1965), which was based on the televised serial The Daleks (1963), and Daleks – Invasion Earth: 2150 A.D. (1966), based on The Dalek Invasion of Earth (1964). Plans for a third film, to be based on the serial The Chase (1965), were abandoned following the poor box office reception of the second film.
Cushing made no mention of the films in his autobiography, although he kept a collection of newspaper clippings about them in a scrapbook.
Dr. Who, as portrayed by Cushing, is an eccentric inventor who claims to have created his TARDIS in his back garden. He is a gentle, grandfatherly figure, naturally curious and sometimes absent-minded, but at the same time is not afraid to fight for justice. He is shown to have a keen and somewhat juvenile sense of humour, and a strong sense of adventure with a will of iron and very strong morals.
