I would love to get in touch with a former Tasc employee!

I found the mail i got from Tasc-Support! It is 2 years old.

There were two adresses: info@tasc.nl and support@tasc.nl (i sent to "support" and the answer came from "info")

The guy, who answered me, was "Ton Peters"
Maybe this info can help you! (and me! )

It still intrigues me from the manual that they said you could have your custom pieces made to work on a Tasc but you had to contact me. I wonder how exactly they went about making that work.

Theoretically it should be no more problem than equipping "non-computer"-pieces with magnets. You only have to use the appropriate coils (best would be to take them from Tasc-pieces!)

Robert,

I only have one set of pieces. I got them from a guy from South America and that's all he had. Only the pieces. No board and no computer. I'll try to check with him again for you. I'll let you know what happens.

You can try to check www.ismenio.com/tasc and see the emails there. Maybe one of them is still active or maybe one of their distributors may have a contact today. I would love to get in touch with a former Tasc employee!

That is very clever. You seem to have a whole set of pieces using just one piece. 

Yes, but not always the piece that i need!

Quote:

Are the secrets of the Tasc gone forever, or is there someone from Tasc who is still interested in chess computers and could explain this strange behaviour?

Maybe there is one, but how can he be reached? www.tasc.nl is gone...

About 1,5 years ago i mailed to Tasc a question about the software for the Chessmachine, but i don't know whether i kept his answer or not...

Is it a Tasc I would recognise? 

No, but it was your knight!

Quote:

I agree with Christian that wiping a magnet across the bottom of a piece can overcome a problem of the board not recognising them.

Thank you both for this hint, but it didn't work. I tried it with a magnet from www.supermagnete.de that should hold 400gr. (I was told that a magnet from a Exclusive-piece can hold about 50 gr.)

Quote:

Maybe the board seeing the white knight as a black king is just a different type of case of non recognition. I had this with a white knight not being recognised after a long period of storage with the other pieces and the magnet trick worked fine.

I will keep this in mind; you never know!

Quote:

There has not been a temperature problem with my Tascs. But this is England. 

As I said, it wasn't your's! I havn't tried it but i wouldn't be surprised if this was a common problem! (maybe some R30 are more temperature-sensitive than others) 

Remember: the R40 with just 30% more speed needs cooling vents!

By the way: the temperature was about  30 degrees Celsius. When i tried it yesterday evening, there happened the same: for about 30 mins everything worked fine (except the white knight! ) and then some keys started not to work correctly anymore; the LCD-configuration changed itself and the R30 was resetting (but the RAM was not deleted; the settings remained the same)

This really seems to be a temperature-problem!

But now to the other problem:
At the end i was a little bit impatient and took the knight apart!
Shame on me, but i forgot to take pictures! >:(

I removed the green felt and what i saw looked like a little wooden plate, covering what i thought to be the the coil.

But when i tried to removed this with a little screwdriver i found that this was a thin flexible plastic-plate . On the inner side a spiral (copper) was printed on it. The outer and the inner end were connected with a very thin wire (about double as long as neccessary)

I could not find any damage.

I bended the plate a little bit, moved the wire around and so on...

Then i put this plate on the Smartboard and  it was recognised as a - Surprise! white knight!

I put it all together again (but not yet glueing it!)

but then the knight was recognised as white king! I pressed the knight a little bit onto the board and it became a black rook!

Sometimes, pressing seemed to have a effect on the recognition, sometimes not!

I repeated the whole procedure and got a white bishop, black rook, white pawn and also a white knight! Sometimes it changed while the plate was lying untouched on the board! Mysterious...

I played with it for about 45 mins.

At the end i got a white knight which seemed to be stable!  I glued it all together again and it still was a white knight!

I'm curious if it will be still a white knight when i try it again this evening! If it will not, then i will take pictures!


But please: don't ask me, what the problem was (or is!) I simply don't know!!!!

The only thing that i definitely changed, was the position of the little wire, but i can't imagine that this was the cause for the problem!

I was told by Bernhard, that only the number of windings of the spiral should be decisive for the recognition of a piece!

Very mysterious...


best regards,
Robert

P.S.: @Ismenio: If the knight still shouldn't be ok, do you have a spare set of pieces for me? IIRC you bought one for your Tasc which seems to work now. If you don't need them anymore, i would buy them!

Robert,

What type of temperature are we talking about? Just curious!
Is it working now?

Robert,

Concerning your R30: this looks very much like a temperature problem. I would advise you to open the main unit and play with the casing open (I am doing this with my PC in summer). So you allow an exchange of air.
If the problem is solved by doing this, you are lucky

Concerning piece recognition: could be also the heat...mybe some electronic parts "misbehave" a little bit if heated up. The frequency changes a little bit...if think the idea of cooling down the pieces, SB and unit down will give you more information (cool cellar maybe???)

What you can also do is to move a strong magnet over the  fields of the SB, and over your pieces. This will erase magnetic fields which might be disturbing the correct piece recognition.

Tasc: White knight recognized as black king!

Hello to all,


yesterday I saw that one of the white knights of my Tasc-chessmen was recognized as black king! The last time I used them was about a month ago; there was no problem!

Could this be a matter of the high temperature? Heat expansion?

The R30 itself had some problems too; it was hanging several times after it was working for about 30 mins! I hope it is no bigger problem!

But the other pieces are correctly recognized! Maybe i should put the knight in the refridgerator before playing! 

The problem started directly with switching on the R30!

Does anybody have an idea, what I could do?


thank you very much,
Robert
