The 68020 version was very expensive as I recall. I guess ChessGenius on the Palm at 16 mhz is comparable in speed to the Roma 12 mhz 68000, and the overclocked Palm (2.5 times faster) is about 47% faster than the Roma 68020 (6.75MIPS vs. 4.25 MIPS). Of course, the original Roma program had the permanent brain feature, and that should be worth at least 30 points. Len
