Doesn't look like it, it says VGA in on that one.
Interestingly there IS a chip that does RGB to S-Video. I bought it and have yet to make up the board but it should work. Interesting to note is the Amiga 500 A520 Modulator does RGB to Composite if that helps at all, I think it might need odd voltages to make it work though.

John Carlsen's C128 80-column Video Digital-to-Analog Converter was released at CommVEx v11 2015 last weekend. (snip) John's C128 VGA adapter webpage has been updated with the latest photos - www.bit-c128.com . After an inquiry from a FCUG member, I looked up John's website and found it to be updated! The website address has been subtly changed to www.bit-c-128.com/He now has categorized the site into multiple pages - Home, Uses, How to Buy, Quick Start Guide, History, and Contact. Interestingly, under History, he notes that the BIT-C-128 Video DAC is now in its second production run after having strong Christmas sales. He even gives CommVEx a plug, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htmJuly 30-31 Commodore Vegas Expo v12 - www.portcommodore.com/commvex

... the VDC can be put into PAL or NTSC mode by software: Set to NTSC: SYS DEC("CDCC"),32,4:SYS DEC("CDCC"),29,7:SYS DEC("CDCC"),126,0 Set to PAL: SYS DEC("CDCC"),38,4:SYS DEC("CDCC"),32,7:SYS DEC("CDCC"),127,0 Now that's quite handy!! I have an old RGBi to analog RGB converter along with an Ambery AV-1 and even if it works, the result is somewhat blurry. I have better results using the monochrome 80 column output from the DB-9. I know the problem is not caused by the Ambery as I have used it in the past as a flicker fixer for an Amiga 500 and the result was excellent. I suspect the digital buffer (74ACT244) on the RGBi 2 RGB board isn't fast enough. Also, since the RGBi 2 RGB converter is supposed to give a signal which resembles that coming from an Amiga, you'd expect the 15kHz RGB to work on an Amiga monitor but it didn't; why is that ? Different type of sync ? Any advice on this ?
