== Introduction == The Amstrad CPC (Colour Personal Computer) series was a series of 8-bit home computers that was manufactured by the british company [[Amstrad]] between 1984 and 1993 (?). The CPC, like most of its contemporary home micros, had an integrated computer-in-a-keyboard design. Also incorporated to the keyboard was the tape recorder of disk drive. In general what Amstrad aimed for was to offer a completely integrated solution at a low price. Just as Amstrad's stereo towers before, A.M.Sugar wanted to provide a solution with as few separate components as possible, with as few cables as possible and as low a price as possible - so as to make the product attractive to the layman who could theoretically buy it off the back of a track (TM of Amstrad's early practices). As a result, he chose ready off-the-shelf components and used low-cost production methods in an effort to bring manufacturing costs down. He also included a monitor to connect the computer to - a move which, while raising the price, was designed to free the home TV from little brats hogging it for a dose of Ikari Warriors while Eastenders was on. This is intented proved to be a short history success, and Amstrad went on to sell millions of CPCs. The combination of low cost, integrated design, good manufacturing quality and some impressive features like CP/M and an 80-column display mode (which was lacking in the competition) proved to be a success both with home users and small businesses, and Amstrad went on to sell millions of CPCs. In all, there were three basic models, the CPC [[464]], [[664]] and [[6128]], plus two more [[Plus|advanced]] models, the CPC464+ and the 6128+. A final iteration was the [[GX4000]] games machine based on the CPC+ computers.   == The 464 ==[[Image:464.png|right|thumb|200px|Amstrad CPC [[464]] with colour monitor]]First came the CPC464, during the summer of 1984 (with production ceasing in 1990). This model used an integrated tape recorder and used 64KB or RAM. It sold around 2 million units in Europe and, technologically-wise, was quite higher than the ZX Spectrum and on a similar level with the Commodore c64 (with the notable exception of the sound chip; while the c64 employed the splendid SID chip, Amstrad opted for a generic sound chip - AY-3-8912 - with unremarkable features). At its core one would find a [[Z80]] clocked at 4MHz while the display was managed by the 6845 CRTC along with a gate-array chip. The CPC464sported a palette of 27 colours and three distinct resolutions: 160x200x16 colours (mode 0), 320x200x4 colours (mode 1) and 640x200x2 colours (mode 2, 80-column mode). Because of its use of the Z80, which was also used in the Sinclair models, many of the games found on the CPC were direct ports of the Spectrum version. As a result, they failed to take advantage of the CPC's extra capabilities, leaving users and reviewers with a bad taste in their mouth, a fact that was going to last for the entire life of the machines. The CPC's operating system was called [[AmsDOS]] (Amstrad's Disk Operating System) and was included on a ROM chip of 48KB. Also in ROM there was the Locomotive BASIC interpreter which made the CPC very fast in BASIC operations, compared to other contemporary machines. == The 664 ==[[Image:cpc664.jpg|left|thumb|200px|Amstrad CPC [[664]] with colour monitor in 80-column display mode]] A few months later Amstrad took the initial design and, building upon the same idea, removed the tape recorder and replaced it with the interface and mechanism of the external Floppy Disk Drive it was selling up to then. The result: the CPC664. Sporting a less colourful and easier-to-type-on keyboard, the CPC664 appealed as a more serious machine and set off to become a success, especially due to its quite fast 3", 180KB/side drive.                == The 6128 ==[[Image:Cpc6128.jpg|right|thumb|200px|Amstrad CPC [[6128]] with colour monitor]] Success never came, however, since a few months after its launch Amstrad presented the CPC6128 which was a 664 with redesigned keyboard (yet again) and double the amount of memory - a great 128KB. This effectively killed off the 664, to its users' frustration, since it offered more at the same price. The 6128 came bundled with CP/M 2.2, DR Logo and CP/M+ (with the GSX extension) and it was quite an appealing solution at a low price. Though the 128KB of memory could not be accessed all at once (due to [[Z80]]'s limitation), the upper 64KB could still be used as a RAM disk and brought into view through memory banking. Even without this amount, however, Amstrad's efficient designed allowed for a TPA (Transient Program Area) of 42KB, more than enough to run all CP/M software.       == The Plus series ==[[Image:cpc464plus.jpg|left|thumb|200px|Amstrad [[Plus|CPC464+]] with colour monitor]] The last models in the CPC range were the CPC464+ and CPC6128+, launched together in 1990. Described as a solution of 'too little, too late', this was Amstrad's effort to prolong the life of its 8-bit computer series in the face of fierce competition from new 16-bit machines (notably, the Atari ST and the Commodore Amiga). The CPC+ were mostly (but not quite 100%) compatible with the original CPC computers, and incorporated a list of new features, like a cartridge port for instant program loading, a better sound chip, DMA, hardware scrolling, 64 (?) hardware sprites of 32 colours each, and a palette of 4096 colours all in a new, sleek case which reminded the higher-end machines. While the CPC+ computers were arguably the best 8-bit computers ever built for the mass market, they died a natural death as the 16-bit era had trully and well set in.                 == Outtro ==All in all, the CPC series met with great success. Although they would never achieve the status of the c64 or even the humble Spectrum series, the CPCs managed to sell very well and attain leader status in several countries. The CPCs were very popular in the UK, Spain, France, Greece and Australia, to name a few countries.
