I've just reanimated my TT and do some tests.
I found out that sync code with video beam (in ST style) works fine on TT. Raster is stable, therefore there is possible to do Spectrum4096 effect.
There is one interesting thing, I turned off data and instruction cache but still see cache effect, "move.w D0,(A4)" have different (but predictable) timing. Maybe that's true funnel can cache one long word...

What's the anti-troll code? That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
