Amstrad CPC: Difference between revisions

The lineup (464 and 6128) remained unchanged until 1990, when Amstrad decided to improve them to a standard closer to the [[Amiga]] and [[Atari ST]]. The new models were the 464plus, the 6128plus, and the [[GX 4000]] game console. They had a new GPU with a 4,096-color palette and hardware sprites; a less processor-intensive sound system; and support for analog joysticks and cartridges up to four megabits. They were also completely backwards compatible. But they were still based on the 8-bit Z80, so they were obsolete in an industry of 16- and 32-bit computers, and failed in the marketplace. The CPC was also more complex than the Spectrum, so it didn't have the second life in eastern Europe that the Spectrum had.
