Hi, I have the Excalibur Deluxe Electronic Chess, and given the identical appearance, and that the model numbers are the same, I think that the Sabre IV is an exact clone of it. Also, according to the wiki-elo-liste the Chess Station could be a clone of these two. Would you agree? And the King Arthur could also be a new clone of these...Monsieur Plastique wrote:It's a relatively early Nelson Excalibur program running on a 6502 I think at 3 Mhz from memory.
Clone suspicion regards,

Yes, all of these machines are basically different versions of the same program running at varying speeds. Nelson would update the program if a new machine came onto the market and the program would have a different version number compared to the last.paulwise3 wrote:Hi, I have the Excalibur Deluxe Electronic Chess, and given the identical appearance, and that the model numbers are the same, I think that the Sabre IV is an exact clone of it.

The clear delineation in the Nelson Excaliburs occurred when the machines began to contain the proper tournament levels as opposed to the earlier ones that typically might have had 72 levels. It was at this point that the playing strength increased noticeably as they began running on an H8 processor.
But earlier machines like King Arthur, Chess Station, Saber IV, etc are for practical purposes the same type of machine and any variances are more due to which particular software version number of the program they happened to have and what speed processor Nelson elected to use in them.

Of all Excalibur comps created by Nelson, which do you think is the better?Monsieur Plastique wrote:Yes, all of these machines are basically different versions of the same program running at varying speeds.

I have considered an answer to this question for four days now. And in an effort not to fan the flames of the now infamous Nelson Question, I decline to reply

No conciliation here.
We are searching the truth, not trying to win the Peace Nobel prize.
I believe Monsieur Plastique say such a thing because he thinks a "better program" by Nelson has no sense at all because he never wrote a decent program....

Better is merely a relative term. I am better at running a 100 metres than Usain Bolt with two broken legs dragging a 2 tonne concrete block. And a rusty push-mower is better at mowing a 2 acre overgrown block of land than a pair of scissors...Fernando wrote:I believe Monsieur Plastique say such a thing because he thinks a "better program" by Nelson has no sense at all because he never wrote a decent program....

Reality is...
you does not use terms as best than or better than when in any case the compared thing is as piece of...
To use your own examples, is like to say that a living body of a paraplegic is faster than a dead corpse.
"Faster", there, does not mean a a thing.

let me finish your unfinished sentence that you termed as "too semantic". Well, here we go: Reality is... too complex to comprehend, because you can never tell when a hill stops being a hill and becomes a mountain, or when a glass is fully full or less than full or half empty, etc. The same applies to the Unnamable Nelson Dilemma. Mr Plastique's diplomacy is actually commendable. Regards from 41 Celsius
