You can get 20Mhz (Palm V) or 33MHz (Handspring) Palm OS machines, but they are much more expensive. Chess Genius uses the 680X0 assembly code (the Palm DragonBall chip uses the 680X0 instruction set) Mephisto Roma chess engine (The 1987 World Champion), which is rated by the SSDF on two platforms: at 1870+/-18 on a 12 MHz 68000 (see #141 on the list: http://home.swipnet.se/~w-36794/ssdf/rlwww004.txt ) and at 1930 +/-27 on a 14 MHz 68020 (see #127 on the same list). On an entry level Palm ($149), the processor runs at a higher clock rate (16 MHz), which will add strength, all other things being equal. I don't know whether Palm's DragonBall processor runs 680X0 code with efficiency closer to the 68000 or the 68020. An earlier post, based on data on the DragonBall chip, thought it was more like the 68020, which would be 1930 +/- 27. Palm Genius does not think on its opponent's time, which should weaken things by about 30 rating points, but the faster clock should add back 12 points, so say 1912 +/-27 SSDF. -Richard
