AFAIK there was no NTSC version of the Paloma.
It was still not available in
March 1999 and Klaus Burkert (father of Picasso) died in April 2001 and probably took all development with him (assuming it had not stopped before then).
Olaf Barthel is perhaps another source of information in the absence of Tobias.
It would not be a case of replacing a chip and it will work. You'd have to replace the entire can tuner (the silver thing) and all the chips inside, perhaps change a crystal, change all the software for the new tuner etc.
