Rumor has it that Jim Cox may have mentioned these words:

I thought that was the Commie series (1084?)... And I thought that was just
one or both of the sync signals - a single TTL chip (7404 hex inverter)
would do the trick.
However, here's my recollection of the some of the tandy monitors:
CM-5 - CGA, absolutely pitiful. .52 or .51mm dot pitch, IIRC. Could *not*
do 80 columns.
CM-8 - CoCo RGB - .42mm dot pitch. Can do 80 column; tho 106 was kinda
tight. (Yes, there are fonts for OS-9 for a 106 column screen... can be
handy if you needed to see a wider-than-80 column layout for something. [[
Some people say 80-column was borderline, a few say it wasn't good enough -
maybe I just have higher-resolution eyeballs, as I've never really had to
squint or anything at 80-column; and my CM-8 was one of the very first off
the assembly line - drove 300 miles round trip to buy it.]]
Atari SC1224 (And yes, I have 2 of these, so I have a "vested interest" in
this thread... ;-) .37mm dot pitch according to Google.
Better, yes, but will it be *that much better* to mod an SC1224, or should
one "bypass the middleman" and use Roy's adapter to hook to an SVGA monitor?
BTW, Digi-Key still caries 13-pin DIN inline plugs & receptacles, so CoCo3
cables just for the SC1224 could be pretty easily made.

 "Easily" depends a lot on your soldering skills & equipment as I'd bet
those DIN hoods are pretty packed in there... ;-)
