The PASOPIA 7 is a computer manufacture by [[Toshiba]] and sold in 1983, most probably only in Japan.
== Facts ==
* This is the successor of the Pasopia 5. It has improved sound and graphics.
* It shares a few similarities with Amstrad CPC, mostly its CPU and Colour Palette.
* The video modes in 8 displayble inks is somewhat typical from Japanese machines, as for the NEC PC8000 series, also hogh resolution (sort of) in order to display Kanjis and asian characters more easily.

But according to videos the palette seems to be the result of the 8 colours RGB + hi-resolution ditherings, hence being a Software palette.

* From the demo we can see that the Pasopia 7 is able to produce the 27 colours via vertical lines in 640x200 video of the basic RGB 8 colours.
While this is visible on modern emulation and modern monitors, this would actually produce real solid extra colours on a CRT monitor.
To dither finely the 8 RGB colours cannot produce more than 27 colours because of redundancy in the result colour from diferent combinaison.
*Opposite colours from the 2x2x2 (1bit) RGB cube would produce grey
Ex : Black + White = grey, Yellow + Blue = Grey.
*some other mix would produce already existing basic colours
Ex : Red + Blue = Magenta, Red + Green = Yellow.
* would only remain :
= 6 intermediary colours : Lime, sky blue, Purple, Sea Green, Orange, Lavender.
= Darker Basic colours when mixed with Black : Dark blue, Dark Red, Dark Cyan...and so on.
= Lighter basic colours when mixed with White : Light red, Light Cyan... equivalent to Amstrad CPC's Pastel colours.
This leads to the 3-level RGB cube generated from the 1-bit RGB cube in high horizontal resolution and CRT monitor effect.
* The same trick may be somewhat possible on the Sinclair QL (256x256x8 may work, 512x256x4 would produce some part of the CPC palette) or NEC PC-8801 (640x200x8) or any machine with basic 1bit (2 levels) RGB palette and 640x200 resolution, using CRT monitor.
