John,

I think it was last year that I called Hilton Hotel corporate office to search for the location of this particular chip. They searched their files and archives but return to me a couple of days later that - they don't have anything - "but their hotels has turnover and change names and ownership".

Turkey will be my next country of search. Then I will try the Hilton corporate office again for the last time.

Thank you for the input.
