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the video display which saw an increase in palette Plus was starting to 4096 colours and gained look a capacity little out of date by 1990 and users resented the substantial price hike for hardware spritescartridge games compared to their tape and disc counterparts.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]]

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]], [[Gate ArrayGX4000 cartridge|cartridge]](without BASIC) and in the interruption mechanism in vectorised mode.

== The GX4000 Games Console ==The GX4000 is a was [[Amstrad]]'s attempt to gain some share in the home game console based on a CPC 464+ without a floppy controller or keyboard (although market, then dominated by the likes of Nintendo and Sega. Like others before it is actually possible to modify one, add a floppy controller and a keyboard and use like others after it as a CPC+), it failed abysmally in its goal. It Despite the fact that the hardware was delivered with two game paddles decent (as the ones delivered with after all the CPC+ modelsseries 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 Burning Rubber on [[GX4000 cartridge|cartidge]] (without basic)bad timing meant that Amstrad's adventure in the home market was about to end.

== Specific Software for CPC+/* The pause button on the GX4000 ==is mapped to the P button on the CPC keyboard. Other than this the 2 digital joysticks are connected, all other keys are not connected.
