I don't think this can be true.  A standard Atari-equipped TT could have up to
10 MB of ST-RAM and 16 MB of TT-RAM.  I think one of my TTs is setup that way
(in's in a box at the moment, so I can't check quickly).

I don't think this observation is valid either.  Falcons can have up to 14 MB
of ST-RAM and TTs (as noted above) up to 10MB.
