== Colour-ROM ==
The KC compact has a colour-rom. Each byte in the ROM defines the R,G and B of an output colour.
{|{{Prettytable|width: 700px; font-size: 2em;}}
|''Bit''||''Function''
|-
|7||not used''
|-
|6||not used''
|-
|5||Green''
|-
|4||Green''
|-
|3||Red''
|-
|2||Red''
|-
|1||Blue''
|-
|0||Blue''
|-

The hardware colour index (defined by the I/O write: A15="0", A14="1", D7="0", D6="1" D3-D0 define hardware colour index), is used as a look-up into the ROM.
Each colour-element (R, G or B) is defined using 2 bits and has the potential to define a total palette of 64 colours. The colour-rom only uses 3 of the 4 possible settings for each colour-element, and it is unknown if two of the settings give the same result intensity.
{|{{Prettytable|width: 700px; font-size: 2em;}}
|''Element Bit 1''||''Element Bit 0''||Intensity''
|-
|0||0||Zero''
|-
|0||1||Half? (this setting is equivalent to CPC half intensity)''
|-
|1||0||Half?''
|-
|1||1||Full''
|-
|}
The colour ROM can be downloaded from the KC-Klub homepage.
