In 1990 Amstrad introduced the "Plus" series which tweaked the hardware These models did not do very well in many ways and added a cartridge slot the marketplace, failing to all modelsattract any substantial third party support. Most improvements were to The 8-bit technology behind the video display which saw an increase in palette Plus was starting to 4096 colours and gained look a capacity little out of date by 1990 and users resented the substantial price hike for hardware spritescartridge games compared to their tape and disc counterparts. Splitting However, the display into two separate windows and pixel scrolling both became full supported hardware features although both were possible on the non-"Plus" hardware using clever programming machines did sell well in France where Amstrad still had a large following due to the success of the existing Motorola 6845classic CPC range there.

An automatic DMA transfer system The range was officially titled as 'Amstrad 464 Plus', 'Amstrad 6128 Plus' and 'GX4000' and the 'CPC' (standing for feeding Colour Personal Computer) abbreviation used in the sound chip older generation was also added but the sound chip itself remained unchangeddropped. Additionally However, many Amstrad users refer to the BASIC command set for disc access was improvedPlus range as 'CPC Plus' or 'CPC+' due to the inherent similarities of the two ranges.

A cut down CPC+ without Klick to see the keyboard nor support for non-cartridge media was released simultaneously as PCB of the GX4000 video game console.6128 Plus [[Mainboard Versions]]

These models did not do very well in the marketplace, failing to attract any substantial third party support. == The 8-bit technology behind the CPC was starting to look a little out of date by 1990 and users resented the substantial price hike for cartridge games compared to their tape and disc counterparts. It's often forgotten that Europe had a large CPC following well supplied by Amstrad it's said the plus machines sold best in France.GX4000 Games Console ==

== The CPC GX4000 is a game console based on a 6128 Plus =='''CPC Plus''' can use cartridges released for the '''GX4000''', but specific software can be created using the extra features without the need of hardware a floppy controller or keyboard (contrary as although it was claimed by Amstrad in 1991). The extra features are not locked by an hardware mechanism but only by a special 17 bytes-lenght sequence send to the CRTC. So, it's is actually possible for everyone to create his own software on the cpc plusmodify one, using the extra features available through add a floppy controller and a 16kb ASIC I/O pagekeyboard and use it as a Plus).See [[Programming ASIC]]Excepted It was delivered with two game paddles (as the extra-features, ones delivered with the Cpc Plus is almost full compatible with the old generation. We can notice some minor differences in emulated components (models) and Burnin' Rubber on [[PPI]], [[CRTC]], [[FDCGX4000 cartridge|cartridge]](without BASIC) and in the interruption mechanism in vectorised mode.

== * The GX4000 Games Console ==The GX4000 master clock is a game console based on a CPC 39.9Mhz (approx) instead of 40Mhz for the 464+ without a floppy controller or keyboard (although it /6128 Plus. The Arnold V specification indicates this is actually possible to modify one, add give a floppy controller and a keyboard and use it as a CPC+)better picture. It was delivered with two game paddles (as This means the ones delivered with the CPC+ models) and Burning Rubber on [[GX4000 cartridge|cartidge]] (without basic)is 0.25% slower than a 464 or 6128 Plus but should have a better picture.

* The GX400 was [[Amstrad]]'s attempt pause button on the GX4000 is mapped to gain some share in the home game console market, then dominated by P button on the likes of Nintendo and SegaCPC keyboard. Like others before itOther than this the 2 digital joysticks are connected, and like others after it, it failed abysmally in its goal. Despite the fact that the hardware was decent (after all the CPC+ series were some of the very best 8-bit computers ever designed), it was a case of 'too little, too late'. Lack of CPC+ specific software, lack of marketing effort and bad timing meant that Amstrad's adventure in the home market was about to endother keys are not connected.

== Specific Software for CPC+/* The following are not connected on GX4000 ==so the associated inputs are not defined (possibly high):=== CPC+ ===** Printer (data and strobe)==== Game creators ====** Keyboard lines 0,1,2,4,5,7,8To complete** FDC** FDD motor** Cassette read, write, motor** The signals /ROMEN, ROMDIS, /RAMRD, RAMDIS, CRTC CURSOR, EXP, Printer BUSY

* When a system cartridge is inserted (this has been verified with a yellow and a green labelled system cartridge), the copyright message and a Ready prompt is displayed. If the fire buttons or directions are pressed on the first digital joystick you see X,Z and the arrows displayed, the same as if you had pressed these buttons on a 464/6128 Plus or CPC. Pressing Pause displays "P". ==Accessing the Plus hardware improvements == Non '''The Plus''' and GX4000 cartridges access the Plus hardware improvements, but specific software can be created using the extra features without the need of cartridge hardware (contrary as it was claimed by Amstrad in 1991). The extra features are not locked by a hardware mechanism but only by a special 17 bytes-length sequence send to the CRTC. So, it's possible for everyone to create his/her own software on the Plus, using the extra features available through a [[ASIC]] I/O page. Except the extra-features, the 464 and 6128 Plus machines are almost fully compatible with the classic CPC generation. Some minor differences are noticeable in the components ([[8255|PPI]], [[CRTC]], [[Gate Array]]) contained in the ASIC and in the interrupt mechanism in vectorised mode. For details about the Plus/GX4000 hardware features, see [[Arnold V Specs Revised]]. == Software == === System Cartridges === See [[Plus System Cartridge]].  === Pure CPC Plus demos === *[[4096 Preview|4096 Preview]] ([[Kevin Thacker|Kevin Thacker]]) *[[Allergy|Allergy]] by [[Semilanceata|Semilanceata]] *[[ASM Intro 1|ASM Intro 1]] by [[Roudoudou|Roudoudou]] of [[Flower corp|Flower corp]] *[[Basic Demo 3|Basic Demo 3]] by [[Roudoudou|Roudoudou]] of [[Flower corp|Flower corp]] *[[Black Sabbath|Black Sabbath]] by [[BDC-Iron|BDC-Iron]] *[[Blob Demo]] by [[Redbox]]*[[CPC+ Desktop|CPC+ Desktop]] by [[Odiesoft|Odiesoft]] *[[Demo Plus|Demo Plus]] ([[GPA|GPA]]) *[[Diamonds|Diamonds]] ([[ZilogMonkey|ZilogMonkey]]) *[[DMA music demo|DMA music demo]] ([[Cadjo Clan|Cadjo Clan]]) *[[Fantasy|Fantasy]] by [[Semilanceata|Semilanceata]] *[[Hate Beats|Hate Beats]] by [[Ukonx|Ukonx]] *[[It was so nice before the crash of the mir station|It was so nice before the crash of the mir station]] by [[Eliot|Eliot]] *[[Kill Max]] by [[OFE|OFE]]*[[Larsen|Larsen]] by [[OFE|OFE]]*[[Lumiere]] by [[Revival|Revival]] *[[LiquidSnake|LiquidSnake]] by [[Revival|Revival]] *[[Sappy|Sappy]] by [[Semilanceata|Semilanceata]] *[[Schnapps|Schnapps]] by [[Shining|Shining]] *[[Simply The Bests|Simply The Bests]] by [[Eliot|Eliot]] *[[Seminoisin|Seminoisin]] by [[Semilanceata|Semilanceata]] *[[Synergy|Synergy]] by [[Ast]] of&nbsp;[[Impact|Impact]] *[[Tragedy|Tragedy]] by [[Ast]] of&nbsp;[[Impact|Impact]]*[[Walking on a scroll|Walking on a scroll]] by [[BDC-Iron|BDC-Iron]] *[[XMas 2008]] Dentro by [[Ast]] of&nbsp;[[Impact|Impact]] *[[Wulf|Wulf]]/[[Ratz|Ratz]] unreleased part of [[Palatine|Palatine]] *[[Ze Meeting 2000 Demo|Ze Meeting 2000 Demo]] by [[BDC-Iron|BDC-Iron]] === Demos with Plus features === * [[20, 21,22 February 1999 meeting Demo]] by [[Benediction]]* [[A Step Beyond]] by [[Dirty Minds]]* [[Genesis demo]] (unreleased ?
