John you are a big tease - but well done for putting at least a tick in the
big wish-list - do we get a youtube demo?

I still maintain there are commercial applications beyond the BBC B etc

Fingers crossed

John T.

Okay.

So I solved all the asynchronous crap. Perfect digitisation of the RGB
output (in the absence of the pixel clock). Re-rendering it with a simple
CRTC, loosely synced to the digitiser, so as to keep those /incredibly/
picky contemporary monitors satisfied.
DVI output (well, HDMI really). VGA too, but that's boring now.

And it's friggin' epicly gorgeous ! Every pixel in its clear, un-washed-out,
un-flickering, consistently coloured splendour.
Source synchronous (no tearing). And with only minimal delay (one, two
lines).

So it can be done ... !

Don't hold your breath for a product though. Some things left to solve, many
more to make more flexible. No teletext (that will be a while new story,
with its very own 6 instead of 16 MHz pixel clock, and need for actual frame
buffer sized interlacing).

More later. Hopefully. Throughout the year.
