Vintage Chess

Estos son post antiguos que tengo en otro blog, creo que son interesantes de tenerlos aca ta,bien:

Colossus Chess 4.0 (a8) v/s GNU Chess

Por fin pude lograr hacer jugar (a través del protocolo UCI) a Colossus Chess 4.0 y GNU Chess para poder generar un nivel al muy buen producto de 8 bits Colossus Chess que era el mejor de la época.

Colossus hizo una buena presentación considerando los 8 bits y 1.67mhz del atari contra:

Hardware: Mobile AMD Sempron™ Processor 3000+ 1794 MHz with 1.152 MB Memory

Bueno el juego lo pueden ver a continuación (para algún tipo de análisis para jugadores) y el archivo PGN.

Finally I made to play both Colossus Chess (3 & 4) against each other, where the last one won without any doubt 9.5 - 0.5

CC3 hardly got a the 4th game ending in a draw. Here it's the tournament in PGN to watch it in some chess software such as Arena.

Finalmente hice jugar a los Colossus Chess 3 y 4, donde el último ganó sin apelación 9,5 - 0,5

CC3 Apenas logró una tabla en el cuarto juego. Aquí les dejo el archivo del torneo en PGN para poder visualizarlo en algún software como Arena.

Sieve of Eratosthenes

TODO: hay un bug en el codigo, probar lo nuevo en cc65.. la version de action ta mala :(

ADVAN COMPILER BASIC
http://www.atarimagazines.com/v4n12/Compiler.html
Advan BASIC is filled with shortcuts like this. By the way, it ran my version of the Sieve of Eratosthenes in 13.8 seconds. The MMG compiler took 9 seconds, BASIC XL took 67 seconds and Atari BASIC hasn't finished yet. If that isn't fast enough, you can rewrite key routines in assembly language from within BASIC. Advan BASIC recognizes assembler mnemonics almost as if they were BASIC keywords. Not only is this great for people who know assembly language, but it can be a teriffic learning environment too.

ADVAN OPTIMIZER
http://www.atarimagazines.com/v6n2/BASICBonanza.html
Advan BASIC was already pretty fast. Now it's the fastest BASIC in Atari history. In our Sieve Benchmark, the Advan Optimizing Compiler is about four times faster than the MMG Compiler, six times faster than regular Advan, 20 times faster than compiled Turbo-BASIC XL and 120 times faster than uncompiled Atari BASIC. In fact, it's more than half the speed of ACTION!- that's getting real close to pure assembly language.

KYAN PASCAL
http://www.atarimagazines.com/v4n7/kyanpascal.html
The resulting object file has a very rapid run-time. Ten iterations of the Eratosthenes Prime Number Sieve (see "First ST Performance Test," Antic, October 1985) ran in about 120 seconds with the screen on. With the screen off, the same program ran in just 80 seconds.
