Atari TT? Falcon? It is more advanced than an ST. It was a BEAST of machine that Atari did not spread. As the last Amigas...
On parallels universes we could be writing in a forum called TOS1.02 Lives! or Workbench Lives!
The other 680x0 machines died too soon. 
All those machines seem to me more powerful than Macintosh of the same age.
Atari did spread Falcon and even give rights for C-Lab continue make Falcon mkII when Atari move Jaguar gameconsoles.
But it was strange how media promote PCs in that time.
Most sad think that there was Spectre Mac emulator for Atari Stacy (Laptop ST) what was faster than Mac Laptop, but people bought two times expensive Mac.
Some of us even read and write to Atari forum
Actually 68k is not dead it turns Coldfire processors. And Medusa Computer Systems makes Atari TOS compatible computer.
And Workbench lives as MorphOS and look what hardware runs it
