You are dead wrong.

From the latest SSDF list:

137 Chess Tiger 14.9 Palm m515 16MB 42MHz   2101   69   -74   100   39%  2180
184 Chess Genius 1.5 Palm m515 16MB 42MHz   1870   69   -78   100   32%  2002
185 Mephisto Roma  68000 12 MHz             1869   18   -18  1519   56%  1827

The last two lines show that a Palm m515 running at 42MHz has approximately the
same processing power as a 68000 running at 12MHz because ChessGenius 1.5 for
Palm has the Mephisto Roma chess engine, source is the Chess Genius web site.

So on the same hardware a modern program (Chess Tiger 14.9a for PalmOS) gets a
rating 230 points above a program from 1987 (ChessGenius for Palm, aka Mephisto
Roma).

So clearly a modern program using the same hardware as 15 years ago is MUCH
STRONGER than a program from 15 years ago.

Today's programs do not need more computing power in order to be much stronger
than those of the '70 and '80.

Where have you been since 1987?

Yeah, sure:
* saving thousands of games in memory. Can you do that with your wooden unit?
* Importing/Exporting PGN games. Can you do that with the wooden board?
* Updating the program when a stronger one is released. Can you do that?
* Customizing the colors. Can you do that? ;-)

I fail to see why the "literature built up over the years" destroy a Palm
program in term of features, sorry...

You are completely wrong, again.

When the speed increases, programs of the late '80 get worse when compared to
today's programs.

This is due to them having a worse branching factor that today's programs.

If you want to check this, I suggest you study the behaviour of Chess Genius for
PC from the slower to the fastest PCs.

If you are not very strong at chess that might be a good choice...

 137 Chess Tiger 14.9 Palm m515 16MB 42MHz   2101   69   -74   100   39%  2180
 162 Mephisto Almeria  68020 12 MHz          1972   42   -40   305   62%  1885

(please note that the hardware of the Mephisto Almeria 32 is several times
faster than the hardware of the Palm quoted above)


Finally I know what you wanted to say. You probably wanted to say that the old
dedicated chess computers still have some kind of magic attached to them, and
that one can feel some affection for them.

And I agree with you.

But please do not pretend that they are technically on par with modern chess
programs running on handheld computers (Palms). They are definitely not. They
are much weaker and Palm programs have simply more features, are simpler to use
and I have no doubt that many people are more attached to their Palms than to
their PCs or their old dedicated chess machines.
