== History & Overview ==
== The Arnold == '''Arnold''' was the internal code name of the first Amstrad CPC prototype, which was built around a MOS [[6502]] CPU. As they choosed the Z80 based programming language [[Locomotive BASIC]] as a part of the core system, Amstrad decided to replace the [[6502]] with the Zilog [[Z80]]. One of the "Arnold" prototypes was sold via Ebay in 2005. == The Gray Grey Amstrad' ==

The first cases of the [[CPC]] 464 had a grey colour instead of the later used black colour. Probably these prototypes have been sent to several software houses to enable them to start developing CPC software before the computers' release.
