From Wikipedia, the free encyclopedia:

   REBEL (or Gideon - the first PC version of this chess engine was named Mephisto Gideon) was a world champion chess program developed by Ed Schröder. Development of REBEL started in 1980 on a TRS-80, and it was ported many times to dedicated hardware and the fastest microprocessors of the day:

  • 1980s – Running on a TRS-80, Apple II, and inside of Mephisto brand dedicated chess computers, it won the Dutch open computer chess championship four times.
  • 1991 – Ported to the ARM ChessMachine and named Gideon, it won the World Microcomputer Chess Championship.
  • 1992 – Gideon won the World Computer Chess Championship, the first time a microprocessor came ahead of a field of mainframes, supercomputers, and custom chess hardware.
  • 1990s – REBEL was ported to Microsoft DOS and then Microsoft Windows and sold commercially
  • 1997 – REBEL won a match with GM Arthur Yusupov 10.5–6.5, the first successful challenge of a chess grandmaster by a commercial program.
  • 1998 – REBEL won a match with GM Viswanathan Anand 5–3 (but lost 0.5–1.5 in the standard time control section of the match). He was rated number two in the world at the time.
  • 2004 – Ed Schröder retired, releasing the last version of REBEL as the freeware chess engine Pro Deo.

This ver­sion of Mephisto Gideon Professional was de­sig­ned for per­so­nal com­pu­ters with o­pe­ra­ting sys­tem MS-DOS (Mi­cro­soft Disk O­pe­ra­ting Sys­tem), which was o­pe­ra­ting sys­tem de­ve­lo­ped by Mi­cro­soft in 1981. It was the most wi­de­ly-used o­pe­ra­ting sys­tem in the first half of the 1990s. MS-DOS was sup­plied with most of the IBM com­pu­ters that pur­cha­sed a li­cen­se from Mi­cro­soft. Af­ter 1995, it was pu­s­hed out by a gra­phi­cal­ly mo­re ad­van­ced sys­tem - Win­dows and its de­ve­lop­ment was ce­a­sed in 2000. At the ti­me of its grea­test fa­me, se­ve­ral thou­sand ga­mes de­sig­ned spe­ci­fi­cal­ly for com­pu­ters with this sys­tem we­re cre­a­ted. To­day, its de­ve­lop­ment is no lon­ger con­ti­nue and for e­mu­la­tion the free DOSBox e­mu­la­tor is most of­ten used. Mo­re in­for­ma­ti­on about MS-DOS operating system can be found here.
