TMS99X8A palette.
Source: TMS9918/28/29 Data Book, page 2-17.
Conversion to RGB was done for MESS by R. Nabet.

First 3 columns from TI datasheet (in volts).
Next 3 columns based on formula :
	Y = .299*R + .587*G + .114*B (NTSC)
(the coefficients are likely to be slightly different with PAL, but who cares ?)
I assumed the "zero" for R-Y and B-Y was 0.47V.
Last 3 coeffs are the 8-bit values.
