Who are you talking to there?
I'll probably pick up one of those single-board converters for my C128, since it can easily be modified for RGBI.
What resolutions does the C128 put out?
Its dot clock is exactly 16MHz for the 80 character screen.
For the 40 character screen the dot clock uses frequencies derived from
the color carrier. In NTSC, it is 8.181818... MHz (16/7 * color clock),
in PAL it is 7.8819888... MHz (16/9 * color clock).

The other board that Steven is looking at then won't work. The other
board is for arcade systems at much lower bandwidth. My guess (based
on everything Mahon has taught me) is that all kinds of beat patterns
(aliasing bars) will show up at the C164's higher resolutions... which
appear close enough to the problematic IIgs modes I witnessed.
