Range specifications and comparisons
(infos taken from wikipedia) http://it.wikipedia.org/wiki/NEC_PC-6001
- 6001 : no built in mass data storages
- 6601 : Floppy disk interface and drive
- CPU : PD 780C-1, seems to be Z80 clone with various clocking, according to video system.

Palette
Here is a comparison between Amstrad CPC palette (theric colours) and PC-6001mk2 supposed palette.
- 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.
Just check the specs from the PC-6001 MK2 and the PC-6601.
Those are basically Amstrad CPCs with extra sound capability and less video modes and palette.
