Yes. It's TTL level. Since posing my question, I've gotten a tiny bit more
1. Some sites talk about e.g. arcade graphics as being "analog CGA" -- I
was acquainted with these being called "analog RGB" but never saw "analog"
and "CGA" together before.
2. There are computers knocking about with actual digital RGB signals, like
the BBC Micro B (IIRC). What I forgot to make explicit in my question was
that I was asking about RGBI (+intensity), which AIUI is the same as CGA.
Now, I'm confused about point 1: did actual PCs with CGA have both digital
(TTL) and analog signaling?
