Hello All.

Well it started some while back but last years many old dedicated are tuned .People did find a way to increase the Mhz
Ore create new PCB,s for existing computers

I have also some upgraded chess computers
I have decided to play with the Par Excellence 16Mhz and Super Constellation 16Mhz on Tournament Level 40/120

Interesting games so far ...2th is running now
First game is a draw out mine point of view at the end
They play a good game of chess to mine opinion of course there are also moves that are not that good

Par Ex 16MHz is rated 2088 on Tournament games ,the SuperCony 16MHz rated 2038 based on Active chess
Based on the first game ,the Par Ex was standing better after 29.f4 but decided to give up his free pawn on the H line
In the Rook Endgame both did play well

Hello

Game 4 , SCony comes better out of the Opening and have good advantage ,but gives it away . SC king side is "wide"open and now the PEx is standing better .Move 41 the SC finds a nice draw ...a5+!! Kxa5 and then is Qe1 needed but the SC plays Rc7?!
After move 45 Rb3 wins easy Ka7 but what does the PEx here with Kxb5 gives all advantage away
Around move 50 it is a always difficult Queen+Rook endgame ,should be draw ...
But on move 69 the SC gives the game away with a blunder Qe4?? PEx Ra1 and over ! 0-1
