Changes

 '''CPC Plus''' can use cartridges released for the '''GX4000''''''''', but specific software can be created using the extra features without the need of hardware (contrary as it was claimed by Amstrad in 1991). The extra features are not locked by an a hardware mechanism but only by a special 17 bytes-lenght sequence send to the CRTC. So, it's possible for everyone to create his /her own software on the cpc plus, using the extra features available through a 16kb ASIC I/O page.(See [[Programming ASIC]]Excepted [[Programming ASIC|Programming ASIC]].) Except the extra-features, the Cpc 464 & 6218 Plus is machines are almost full fully compatible with the old CPC generation. We can notice some Some minor  differences are noticable in emulated components ([[PPI]], [[CRTC]], [[Gate Array]][[Gate Array|Gate Array]]) and in the interruption interrupt mechanism in vectorised mode.
