Mephisto (chess computer). Mephisto was a line of chess computers sold by Hegener & Glaser (H+G).  In addition to integrated travel and sensory computers, they also sold a line of modular electronic autosensory boards (Modular, Exclusive, München, and Bavaria) which could accept different program, processor, and display modules.

Its strongest software was written by Richard Lang, who later ported it to personal computers as Psion and ChessGenius. Lang's Mephisto programs won six World Computer Chess Championships (WCCC) from 1984 to 1990. H&G also sold engines licensed from Johan de Koning, Ed Schröder, and Frans Morsch. Different models used different 8-bit, 16-bit and 32-bit processors, including MOS Technology 6502, Motorola 68HC05, Motorola 68000 and others.

Hegener & Glaser and its Mephisto brand were bought in 1994 by Saitek.  Their computers currently sold under the Mephisto brand use programs written by Frans Morsch.
