If you are at all worried about this issue go for the A2000.  Nobody
is giving any guarantees that a Fat Agnus-like chip *can* be used in
the A1000.  I still think I have enough tricks to solve the timing issues.
George "Mr. A500" Robbins, expressed doubt as to the feasibility.  Mr.  Robbins
has more electronics experience than I, and much more knowledge of the Amiga
chipset.  This still does not mean I won't try.  There is no task I like
more than the "impossible" task.  (Want to see raster-line interrupts on
a Vic-20?  Sprites in the border on a Commodore-64?  Non-Soviets on Mars? :-)

In no case would the upgrade be exceptionally cheap.  The chip alone would
be hard to get and costly.  Several hundred total by the time the board is
populated with 512K.  And, it is not even at the 'vapor' stage yet (Amiga
Live! anyone?).  Talk to me a few months after Commodore starts shipping N
Meg. Agnuses.  Don't hold your breath until then.

Yes sir, passenger service to the moon starts November 1, 1969.  Cash
in advance, please!
