Is it some kind
of "Super CGA" that wasn't really supported by anyone?
I know some game companies "tweaked" certain memory registers or something
so that standard CGA could do 320x200x16 colors, but as far as I'm aware,
there was only 320x200x4 and 640x400x2 for CGA, 640x400x16 for EGA, and of
course 320x200x256 for MCGA. (The latter was what my Compact IBM PS/2 Mac
wannabe had)

Both the IBM PCjr and the Tandy 1000 line had 320x200x16. If you look at
the system requirements of late 80s, early 90s Sierra games you'll find
many of them support 'Tandy Graphics'.
As a side note... the Tandy 1000 line also supported three-voice digital
sound--also stolen from the PCjr. You will also find this supported in
those games too.

It was thus said that the Great Scott Walde once stated:

When IBM was developing the IBM PCjr, they specifically went to Sierra to
have them do a game for the upcoming PCjr. That game was "King's Quest"
(of
which I do have an original copy of) and that started that particular genre
(sp? I don't even know where to begin) of games.
It was interesting play that game on a PCjr, in that you could actually
watch the scenes being drawn, with objects that could be manipulated
suddenly appearing when the scene was finished painting. In fact, there was
a keystroke (Alt-P? Alt-Q? Alt-E? It's been awhile) you could hit that
would cause the scene drawing routine to slow down enough to see individual
pixels being drawn. Quite cool.

I'm sure my 3270pc handles a "better" quality CGA. It just looks like
EGA, thought it was... It was running a version of Norton Utes and it
was just beautiful turquoise blue set and clear characters.
I'd have to think this was better than CGA, especially since it took two
coupled long cards to run the video...
