Make Ys available on the RGB connector

[sdsnatcher]

Please add the Ys signal to the RGB connector. The pin-5 of the DIN-8 MSX RGB connector was meant to be the Ys signal from the VDP.

To save some pennies on a transistor, many MSX models came with just a resistor divider connected to that pin.

But for those on the SCART world, it's very useful to have a funcional Ys pin, since the TV can superimpose the MSX image over other sources.

I attached here a screenshot of how it was implemented on the Philips NMS-8245.

There are a lot of free inverters on the current Omega schematic, and any of them could also be used to implement the Ys signal too:

Thanks for the suggestion! I'll add it to the next revision.

Since Ys is terminated with 75 Omh resistance this is probably too much for 74HCT04. Increasing series to 150 Omh results in 18.7 mA current - pretty high, but acceptable for 74HCT.
74ACT04 can source up to 24 mA, but is it suitable for a clock generator?
