There are more that VGA64 or SCART512 adaptors in the I/O BOARD ATLAS for CYC1000 and MAX1000. Here we indicate the solution with a real COMPOSITE VIDEO for I/O BOARD ATLAS, the same way as we did in the VGA222.
COLOR_PAL Color Video Composite PAL modulator using Verilog Outputs: 7bits modulated output. Use a DAC to get about 1V peak to peak with the 75 Ohm TV load. Tested on a Philips TV from 90s.
512 Colors Inputs: RGB (3:3:3), syncs and a 35.46 ~ 36.00 clock. Includes a logical YUV matrix and QAM Encoder
64 Colors Inputs: RGB (2:2:2), syncs and a 35.46 ~ 36.00 clock. Uses a precalculated waveform
