Yup, 1024K of fast RAM, and 128K of slow RAM (banks $E0 and $E1).  This does
not include the 64K sound RAM, which is still there.

A Meg is 1024K, if you ask me or any other reasonable person. :-)

There will be a fairly detailed Technical Note on this in September.
Additional toolsets now in ROM: Window Mgr, Menu Mgr, Control Mgr, Line
Edit, Dialog Mgr, Scrap Mgr, Font Mgr, List Mgr.  There are various
changes/improvements to the Control Panel CDA and Monitor.  (That's
not nearly everything--just the highlights.)

You can now set slot 1 or 2 to AppleTalk and have slot 7 free for your own
card.  (Previously AppleTalk was limited to slot 7, but it still messed up
screen holes for slot 1 or slot 2, effectively taking 2 slots.)

Slot 4 no longer needs to be switched in for the Event Manager or the
Miscellaneous Tools to use the mouse.  For P8 applications that make
slot-based mouse calls, you still need slot 4 set to Mouse.  (Not all
P8 applications necessarily do that, but most probably do.)

I'm not sure what the press release was referring to there, but it sounds
like the advantage you get by running tools (especially QuickDraw II)
from ROM rather than RAM.  (Running from ROM, the system doesn't have
to pause for 10% of the time to let the hardware refresh some RAM.)
