True.

The PAK68 was designed to be swapped against any 68000 proc. It's not ST
specific and does not fit in the ST enviroment nicely.
A ST specific board can do pretty much more.

The main problem with the 020 cache is self modifying code.
The external, write trough cache of the 16 MHz 68000 boards works well,
the 020 and 030 internal chaches won't.
As Alan said, some programs will loose on the TT; the reason is the
cache.

For me, the "if" is true.
I'll believe in this machine, if I could buy one at my dealer's.

Mr Hartman said, it would ship Sep to Okt 1989 (march, CeBIT).
This statement was corrected at the Atari fair in Duesseldorf to Nov 89.

Now it's "early 1990".  Too bad.  Now, Nov, is the time, everybody
discovers, he has something left in the budget.  He thinks about what to
spend it on. 

He will not spend it on a non-existing machine...
