Ok, another point then:
I know a guy who built his own Atari 8-Bit laptop which contains an Atari 8-Bit machine and a tft display that he bought on eBay.
The enterprise that sold it was ready to make up the controller settings for vintage computer use.
I think it should be possible to make a vintage computer tft display that could actually display any Atari resolution from 8-Bit to 32-Bit machines, without looking too bad.
I don't know though how that special TT medrez signal would be shown on it, and I don't know about ECL.
We already discussed that, but I think we should have a talk on that topic again when he's coming around next time.
