Unidentified Model
- 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 (Schneider)
- With Schneider logo and grey text on tape drive.
- Grey control keys (unlike multi-colored ones found in other countries).
- German CPC 464 (Amstrad) (should exist?)
- Produced after the Amstrad-Schneider partnership ended in 1988. Now having an Amstrad logo on keyboard, unknown if/how such late german CPCs differed from english CPCs - they might have grey control keys, or german text on tape drive...?
- German CPC 664 (Schneider)
- With Schneider logo and german text on disc drive.
- Grey control keys (unlike Blue ones found in other countries).
- German CPC 6128 (Schneider)
- With Schneider logo and german text on disc drive.
- There's also a version with slightly different text/design (see here)
- German CPC 6128 (Amstrad)
- Produced after the Amstrad-Schneider partnership ended in 1988. Now having an Amstrad logo on keyboard, but still having a german colour table on the disk drive.
Spanish
Amstrad Ordenador Personal en Color
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...?
- Spanish CPC 464/664/6128 without Ñ key Pre-472, did such models exist?
- Spanish CPC 472 without Ñ key (more info)
- Early version, still with english keys
- Spanish CPC 472 with Ñ key (more info)
- Later version, with spanish keys
- Spanish CPC 464 with Ñ key
- Spanish CPC 464 with rebadged Ñ key (Schneider)
- Actually a German Schneider model with gray keys.

Danish
Amstrad Colour Personal Computer
Older danish 464s had english keys, newer ones (with flat keys) had danish keys...
- Danish CPC 464 (should exist)
- Danish CPC 6128
- BIOS ROM in Danish 464
- BIOS ROM in Danish 6128
Other
- 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.
- KC Compact (more info)
- East german CPC clone - lacks some function keys.
- Aleste 520EX (more info)
- Russian CPC clone with russian keyboard - with additional MSX-style function keys.
- GX4000
- Has only one || Pause button (mapped as "P" key in keyboard matrix)
Mechanics
- First 464 Keyboard Circuit (PCB)
- Printed-circuit-board with wire-cables.
- Second 464 Keyboard Circuit (CPC664-style single-foil)
- Single "membrane" foil (with 19pin connector)
- Third 464 Keyboard Circuit (CPC6128-style dual-foil)
- Two membrane foils (with 2x10pin connector)
- CPC 664 Keyboard Membrane
- Single "membrane" foil (with 19pin connector) (Seems to work more like the old PCB keyboard)
- Connections are closed when the key touches the contacts on the foil.
- CPC 6128 Keyboard Membrane
- Two membrane foils (with 2x10pin connector)
- Connections are closed when the key presses the two foils against each other.
- CPC Plus Keyboard Membrane
- Two membrane foils (with 2x10pin connector)
- Same as in CPC 6128, but with connection cable at rear side.

- Aleste 520EX - ???x???x?? mm
Character Set ROMs
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).
English
English BIOSes
- 40009 English 464
- 40022 English 664
- 40025 English 6128
- 41???-? English Plus (EPROM in System Cartridge)
Default Symbols
The english BIOSes are also used in german models. Until around 1986 (when localized keyboards/BIOSes were invented), the english BIOSes were also used in spanish/french/danish CPCs.
French
French BIOSes
- 40050 French 464
- 40051 French 6128
- 130Z001 41090-1 French Plus (EPROM in System Cartridge)
Special Symbols
- chr(40h) "à" instead "@"
- chr(5Ch) "ç" instead "\"
- chr(5Eh) "^" with different shape
- chr(7Bh) "é" instead "{"
- chr(7Ch) "ù" instead "|"
- chr(7Dh) "è" instead "}"
- chr(82h) "°" instead umlaut symbol
Changed chr(7Ch) means RSX commands become ùCPM instead |CPM.
Spanish
Spanish BIOSes
- 40037 Spanish 464/472
- 40038 Spanish 6128
- 130Z001 41091-1 Spanish Plus (EPROM in System Cartridge)
Special Symbols
- chr(81h) "Ñ" instead "´"
- chr(83h) "Pt" instead "£"
- chr(8Bh) "ñ" instead "±"
The changed pound/peseta currency symbol may result in some confusion, since the actual exchange rate is unlikely to be 1:1.
Danish
Danish BIOSes
- 40??? Danish 464
- 40??? Danish 6128
- 40???-? Danish Plus (probably doesn't exist?)
Special Symbols
- chr(30h) non-slashed zero, to avoid confusion with letter "Ø"
- chr(5Bh) "Æ" instead "["
- chr(5Ch) "Ø" instead "\"
- chr(5Dh) "Å" instead "]"
- chr(7Bh) "æ" instead "{"
- chr(7Ch) "ø" instead "|"
- chr(7Dh) "å" instead "}"
Similar as in french, RSX commands like "|CPM" become "øCPM".
Notes
- 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 "|".
