Changes

The last models in the Amstrad 8bits range were the Amstrad 464+ and Amstrad 6128+, launched together in 1990. It couln't be called "CPC" because Amstrad were sued by another firm still using it. 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 plus series 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, DMA for the AY soundchip (managed with another Z80), hardware scrolling, programmable interruptions, 16 hardware zoomable sprites (not vectorized) with 15 other colours than the bitmap palette, and a palette of 4096 colours all in a new, sleek case which reminded the higher-end machines. While the "Amstrad Plus" computers were arguably one of 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.
