Mephisto Dallas, a dedicated chess computer module by Hegener & Glaser released in late 1986 for their Mephisto module systems. Mephisto Dallas was Richard Lang's further development of the Mephisto Amsterdam, the winner of the previuos year's WMCCC, still persistant inside a 64 KiB ROM but using 64 KiB of RAM. Improvements were mentioned in evaluation and search, combining enhanced tactical skills with a strategic grasp of pawn stucture, weak pawns, advanced passed pawns, minority attack and king safety.

=68020 vs 68000= Dallas was Lang's second coup with Mephisto, like its competitors with three incarnations playing at the WMCCC 1986 in Dallas - all three on a 68020 processor at 30 MHz - Mephisto 3 won the title with 6/7, only losing the last round vs. Rebel aka Recom Deventer A. Another 68020 Mephisto also played in the evening at the simultaneous scheduled ACM 1986 only a foot walk far away. Opposed to the Amsterdam, where a 68020 version which actually won the title was not sold, but only a 68000 module with World Champ button, the Dallas 68020 version was released with a 14 MHz 32-bit CPU, beside the cheaper 12 MHz 68000 module with only 16 Kib of RAM, both with the same World Champ 1986 button. However, at Aegon 1987 Mephisto Dallas 68000 became best computer - 3rd with 4½/6, followed by Mephisto Dallas 68020, 4th with 4/6.
