Laut Wunsch moechte ich jetzt gerne weiter Berichten ueber den Sinclair ZX81.


Fuer den Sinclair ZX81 gab es eigentlich sofern ich weiss nur 4 kommerzielle Schachprogramme:

ZX81 Chess - Micro-Gen - Programmierer: Unbekannt Jahr 1981
ZX81 Chess II - Artic Computing - Programmierer: Unbekannt Jahr 1981
Super Chess - CP Software - Programmierer: Unbekannt Jahr 1982
1k-ZXChess - Programmierer: David Horne Jahr 1982/1983 (Schon berichtet)

Die ZX81 Chess, Zx81 Chess II und Super Chess wollte ich mal gerne Testen und fuer Dedicated Oldie Gegner suchte ich mir wieder 2 passende mit ungefair den gleichen Takt.

Fidelity Chess Challenger 10 - 1978

Prozessor: Z80, 4 MHz, 8 Bit
Speicher: 4 KB ROM, 0.5 KB RAM
Bibliothek: ~100 Positionen
Programmierer: Ron Nelson
Elo: 1300

Fidelity Chess Challenger Voice - 1979

Prozessor: Z80, 4 MHz, 8 Bit
Speicher: 8 KB ROM, 1 KB RAM
Bibliothek: ~500 Positionen
Programmierer: Ron Nelson
Elo: 1359

Beide spielen mit einen hoeheren Mhz aber weniger RAM da ich den Sinclair ZX81 mit 16k RAM spiele.

ZX81 Chess II - Artic Computing - Programmierer: Unbekannt Jahr 1981

Man kann kaum differenzen erkennen zwischen ZC Chess und ZX Chess II

Ich hatte das folgende mal gelesen ueber ein Test der in 1982 gemacht wurde und in eine Sinclair Zeitschrift geschrieben wurde. Daher war ich ganz Gespannt ueber die naechsten Spiele:

I now refer to a letter I received from David Egdoll of Glasgow. He has sent details of games played against versions of chess for the ZX-81 and other chess computers. He has bought the first Artic Chess program and his comment was: "I found it played fairly well at level three but unfortunately it took too long to make a move at that level".

True to the computer industry, a ZX Chess II appeared from Artic. Edgoll also bought a Micro-Gen version of chess. He says that he was not impressed with its standard.


He has included details of games played against Artic ZXchess II and the Voice Challenger, a dedicated chess computer. I was amazed at the results and I think you will be. The ZX-81 playing at level two and the VC at level three, the 81 won two out of two games. The 81 on level two against the VC on four, still won two games and had two draws. With the 81 on three and the VC on five to six, the 81 won four, had one draw and lost one. That mounts up to something stunning; out the 19 games played, the 81 had six wins, one loss, and three draws.

Those results are revealing, to say the least, I suppose it proves that the ZX-81 can, with the proper software, match and may exceed dedicated chess machines. Whether that would be so over a large number of games I am not sure but over the few it looks as if that might be true.

I should like to see a game of chess between a ZX-81 and a chess computer. If anyone would like to send one I will include it. Has anyone other comments on what has been revealed? I think that a great deal can be said about such results. Could it just be that the skill presented by the ZX-81 is superior to the Voice Challenger?

Voice Challenger is made by Fidelity Electronics. ZXchess and ZXchess II are produced by Artic Computing of Hull.

Bd3??

Wow der CC Voice sieht c3 garnicht! Jetzt kommen aber die bekannten Endpiel fehler von diese beiden alten Programme...

66. h7 Bxh7 67. Nxh7??



Jetzt aber c3 und Schluss!

c3! 68. Ke3 Kc4?

wow es wird immer schlimmer !!

Das war nicht gerade das Resultat worueber das Sinclair Magazin berichtet hat, aber doch zeigt der ZX 81 das er gegen die Schachcomputer von 1978 -1980 bestimmt gut abschneiden kann.

So, damit ist Schluss mit das Berichten ueber den Sinclair ZX81.
