Buying a foreign STF will increase the cost because of packaging and stamps... Or the travel price... I am closer to atlantic sea than any other foreign frontier...
(As far as dolphins have no ATARI to sold ;-)
Any way this story learn me something. I found a doc with partial electronic schemas of the STF/STFM and now I do understand what the M from STFM stand for : it stand for RF Modulation. That make the difference between my french one (STF) that only have a RGB output and for exemple an english one with RF modulation (Antenna output). The schemas show that conversion from RGB to RF signal is done by a "single main" componant : the RF Modulator (and of course some resistors and capacitors). Unfortunatly the doc I found doesn't mention the componant name of the RF Modulator. It's just a black box soldered in "MOD1' place on the copper board. I guess this "MOD1" componant depends of the country the STFM is sold (not the same scope of frequencies used for television and not the same kind of modulation especialy for sound AM or FM). Any way this wouldn't solve my problem because I expected the RGB conversion to be done by several boxes, each one carrying on a part of the conversion. For exemple an RGB to YC conversion box following by a YC to composit and endind by a composit to RF modulated signal... So that I would have been hable to derive the YC signal to an additionnal S-Video plug...
Bad luck !
I have also found several schemas to build an external RGB to YC converter. But they all seem to used some old componant no more available and no more produce such as Motorola MC1733 or Analog Device AD724.
