• Amstrad CPC 464 with new logo and grey keys
• Normally grey keys were found only on german Schneider models, not on Amstrad 464.
• Possibly this is a late german model (made after the Schneider/Amstrad partnership ended)...?
• Though this link says it's "most common" in UK...?
• Btw. better "non-diagonal" picture would be nice.

German

Schneider Colour Personal Computer

German CPCs have normal english keyboards. The keyboards (or case) is only different in so far that it is labeled Schneider instead Amstrad, and the 664/6128 have german colour tables on the disc drive. And, the keys are gray, unlike the more colorful Amstrad ones.

• German CPC 464

• German CPC 664

• German CPC 6128

From around 1988, german CPCs were sold directly by Amstrad, not by Schneider. Unknown if these were normal "english" models, or if they still had Schneider-style keyboards... like 464 with grey keys, and 6128 with german color table on FDD unit.

• German Amstrad CPC 464 (non-Schneider) (should exist?)

• German Amstrad CPC 6128

Spanish

Before spanish laws led to the 72K fake and to the spanish keyboard, normal english CPCs might have been sold in spain - unknown if this has really happened - and if so, if they had the spanish Ordenador Personal en Color text on them...?

• Australian AWA models were shipped with normal english keyboards (with the standard Amstrad logo above the ESC key), the only difference is that LK1 and LK2 are shortened on the mainboard, so the BIOS displays Awa instead of Amstrad in the boot message.

Together with the customized keyboards, the BIOS ROMs character sets were changed accordingly. The new characters are potentially useful for home-use, but may result in compatibility problems when importing/exporting software to/from other countries - or even within the same country (the new character sets were invented around 1986, so older french/spanish/danish CPCs didn't support the new symbols).

Similar as in french, RSX commands like "|CPM" become "øCPM".

• According to soft968 the official language variants are: Spanish, French and Danish. And, presumably, English was official, too.

• Although french/danish charsets don't support "|", even newer user manuals (like french cpc+ manual from 1990) still refer to RSX commands as "|CPM" and describe to press shift+"@" to get the "|".
