It's an RGB interface - without support for the 'I'. I also believe it
is not pure TTL, as it understands and responds to varying levels on the
inputs. The RGBI adapter takes advantage of this last fact.

Just picked up
a Wei-Ya ACV-011 CGA --> VGA converter board with the
intention of using it with a Commodore 128 (and possibly Amiga). It
doesn't have a true TTL input, but there is a C128 enthusiast out there
who published a small circuit to do the RGBI --> CGA interface.
Err, what is a 'CGA Interface' if not a TTL-level RGBI one?
