Except that the falcon only allows 3 memory configurations.  1M, 4M, and
14M.  You can't have only 2M of memory.

If this is interlaced, it SHOULD work, it'll have SOME flicker, but TV's use
slow phosphor, so it won't be as noticable on a TV as a monitor.

Again, there is no 2 meg configuration.  Though 640x400 should give too much
display contention to get good frame speed, 640x200 might be usable.

It's probably fast enough to do simple graphic moves, but nothing complex. 
The DSP doesn't really have the "oomph" to pretend to be a blitter.

I've seen posts from people that work for Motorola and know EXACTLY what the
56001 can do.  They tell me the 56001 is not powerful, or precise enough to do
large graphical computations.  The 96001 is supposed to be much better for
this.  In any case, you lose the DSP to do audio things if you attempt to do
graphics with it.

The DSP doesn't give you the sound, the DAC's do, however, i'm sure the DSP
feeds the DAC's so you will probably lose your sound.

Well, it's program and data have to be stored somewhere..

Well, knowing Atari's penchant for being dishonest, and alluding to things
that aren't so, I'd say it's a possibility, but, for those that buy a jaguar
(if it ever sees the light of day) I hope not.  That would be one SLOW game
system.
