Working on I/O Board update
How about 24bit video output with DAC chip? Also with audio DAC.
Chinese New Year holiday is slowing development, but i hope i couple weeks i will finish it.

Thank you this will be a great upgrade. Will be fun to see a comparison
It sounds amazing, thanks for your work!!
Awesome work Alexey!
Would this be a superior option than a hdmi to vga adapter for a high end PC CRT?
Need to assemble the board and test first.
I wonder if IO6/3V jumper is required or direct connection to IO6 will be sufficient? Is there an adapter requiring 3V on USER port?
Very exciting. Are you going to use a different resistor on the sync?
which resistor you are talking about?
Awesome! Looking forward to trying it out! It might be a bit of an ask to add in an optional spot for a THS7374 and a place for a cap / inductor combo for a luma trap for YC. But there is also always the external option.
As long as that doesn't affect RGB or YPbPr, sounds like an awesome idea!
Very cool! I'd love to help test - I can double check voltages and black levels for you. Also, any chance of a power button as well?
The is no much space for power connector, so currently no power button yet. I will keep in mind such option. DAC chip handles black/white levels automatically, so probably it will be correct already. The only question currently is how it will handle YPbPr/YC modes. This is something i have to try when i will get all parts.
Like the HDMI direct video?
Well, Analog output is originally a "direct video" from the core. 24bit RGB can give a better video from cores providing such colors. Originally I/O board was providing 18bit RGB which is enough for 90% or cores.
