Yeah, I'm pretty sure. On Aga with double scan modes it's 16, I think.

I might be wrong, but it's pretty easy to verify. Just open a screen, and write $dff180 with alternating values in a loop. On a 68000 just unroll the loop. Shouldn't matter if you do it using an OS screen or a 'hit the hardware' screen.

I thought that too, but it may indeed be incorrect.
