Hallo Willi,
Yes 1 played in Dieren(Holland) the last game,for the WC it played against Ed Schroder order Lang . And it lost in the endgame.I have it in a book here somewhere i think it was 1992 ore 93
The Spracklens where hired(contracted) by Saitek to become WC.
After this disapointing result ,Saitekmanagment where not happy.
And if they on there own left ore be fired the Spracklens . i do not for sure.
The problem with the 52Mhz was the cooling,that is a reason i think they produced it with 20Mhz to be on the safe side.
Also i know at a Aegontournament the 52MHz played vs Larry Christiansen
And Larry did smoke,because of the heat ,they set there a windcooler wich turns from left to right, and suddenly Larry get the ashes of his cigaret in his face!they all laught about it .This i have from Cock the Gorter.I am pretty sure that there where 2 52MHz machines there.I have personnaly contacted Dan Spracklen but he also do not know where they are. He have it not he said
I heard there is 1 by Niggemann, the other is a big ?
I write this in english because in german i would sit here a hour
Kind regards,Hans
