This was incorrect.  Permanent brain may be added in a later "pro" version,
according to Richard Lang.

Now that I have received the registration code, I have done some more testing
putting Palm Genius and the Sapphire II on more equal footing.  Results so far
are 3.5 - 4.5:

Genius vs. Sapphire II (no permanent brain)
	2 sec/move each: 1 0 0 1
	5 sec/move each: 1 = 0 0

Games available on request (not PGN, but long algebraic dump from Novag serial
port).

Observations:  After registration, Genius's book doesn't get much deeper.  Two
losses above were due to a poor opening out of book.  Genius won two of the
above games in the endgame!  Maybe the Sapphire's small hash tables aren't such
an advantage after all.
