==Palette==
Here is a comparison between Amstrad CPC palette (theric colours) and PC-6001mk2 supposed palette.
[[File:NEC PC6001 palette.png]]
*The palette has 15 colours and one transparency channel ink enabling to overly the computer's video over another TV video (as done with MSX1 or Thomson MO5/TO7 computers)
*This palette is actually available on Amstrad CPC computers as it features black+grey+white, the 6 basic RGB cube colors : Red, Green, Blue, Cyan, Magenta and yellow, and cross colours : Orange, Lime, Seagreen, Mauve, Purple, Sky blue (those are CPC palette names)
*It is quite an exotic and colorful palette, and it doesn't enable proper gradiants like most other comparable 16 ink palettes.
=CPC related?=
Those are basically Amstrad CPCs with extra sound capability and less video modes and palette.
