1 Meg Fat Agnus.  It supports 1 Meg of Chip RAM, programmable display rates
to support new video modes and PAL/NTSC in the same chip, and a few more 
details, but that's the basic idea.

No such critter.

Ditto.

>4) ECS Denis. what's it do?

That's Denise.  She's the display chip, and is now capable of more display
modes.  As well as all the old modes, ECS Denise does a number of modes that
use 35ns pixels rather than the 70ns (hires) or 140ns (lores) the old
chips did.  Examples of these modes are 1280x400 or 640x960 interlaced and
640x480 noninterlaced.  All 35ns pixel modes support 2 bitplanes maximum,
with a palette of 64 colors.
