New development: GTIA in CPLD
The new CPLD solution is already working. Features:
Standard RGB output
Sharp, clean image
True 256 colors
16 luminance levels available in all graphics modes.
Two colors in hi-resolution graphics
P/M colissions, trigger inputs and consol keys are supported by the old chip.
