Re: IIe Analog RGB - rare, unpopular, both?

[vladitx <vladitx@nucleusys.com>]

So far I know about two types of RGB for Apple2:

1) IIgs-like (thanks to A.Freed), which does kind of "nonlinear"
processing of sliding 4-bit window to avoid most artefacts

2) very simple (found in local clones) which simply maps every 4-bit
tetrade to RGBI signals.

I suppose this #2 could be "digital RGB"? What about "analog" then,
could it be one of #1 or #2 but just with analog output levels instead
of TTL?
