'''Mephisto Roma''',<br/>
a set of [[Dedicated Chess Computers|dedicated chess computer]] [[Module|modules]] by [[Hegener & Glaser]] released in 1987 for their [[Mephisto Module Systems|Mephisto module systems]], like its predecessor [[Mephisto Dallas]] as [[68000]] and [[68020]] versions @ 12 and 14 MHz with 16 and 64 KiB of [[Memory#RAM|RAM]] respectively. Thus, the program was the further development of [[Richard Lang|Richard Lang's]] Mephisto series, winning the third consecutive title at the [[WMCCC 1987]] in [https://en.wikipedia.org/wiki/Rome Rome] ([https://it.wikipedia.org/wiki/Roma Roma] in Italian), again the site eponym of the computer modules. The [[WMCCC 1987#Commercial|Manufacturers Championship]] was a duel between [[Hegener & Glaser]] and [[Newcrest Technology]], where three Mephisto Roma on 68020 @ 25 or 28 MHz <ref>[http://www.elpeon.com/index.php?mod=tm Mephisto Turniermaschine Roma 68020 25Mhz | elpeon.com] (German)</ref> outclassed three [[CXG Sphinx]] with a [[Intelligent Software]] program by [[David Levy]] and [[Mark Taylor]], running on a 68020 as well, with a stunning 9:0 result - while the games were more closely than the results suggested <ref>[[Kaare Danielsen]] ('''1987'''). ''The 7th World Microcomputer Chess Championship, Rome, Italy, September 14-20, 1987''. [[ICGA Journal#10_3|ICCA Journal, Vol. 10, No. 3]]</ref>. The cheaper Roma II [[68000]] module was released two years later.

[[Kaare Danielsen]] praised [[Richard Lang|Lang's]] programs in general in his [[ICGA Journal#10_3|ICCA Journal]] report of the [[WMCCC 1987|Rome WMCCC]], where [[Psion]], still Lang's development base for his Mephisto programs, also won the Software group <ref>[[Kaare Danielsen]] ('''1987'''). ''[[WMCCC 1987|The 7th World Microcomputer Chess Championship]], Rome, Italy, September 14-20, 1987''. [[ICGA Journal#10_3|ICCA Journal, Vol. 10, No. 3]]</ref>:
Clearly, Richard Lang has produced the strongest microcomputer program in the world. It searches 4-5 [[Ply|plies]] [[Brute-Force|brute force]] plus up to 6-7 plies [[Selectivity|selective search]]. The program contains a lot of [[Knowledge|chess knowledge]], which is used both in the [[Search Tree|tree]] and to create [[Piece-Square tables|piece-value-tables]]. The chess knowledge was obtained from chess masters, who analyzed games played by the program. The program has an [[Asymmetric evaluation|asymmetric evaluation]] function, which emphasis safety (has rules like 'do not start a wild attack, but worry a lot if the opponent does so'). The program searches about 4000 [[Nodes per second|nodes per second]] on a 28 MHz [[68020]], but this includes a thorough analysis at every node, including a [[Static Exchange Evaluation|swap-off evaluation]] (static analysis of captures instead of a [[Quiescence Search|capture search]]).
