IIRC, didn’t most older pc monitors have a setup mode where one of the options was
interlace or non-interlace.

I think you have that backwards.
TVs use interlace. Older PC displays may do so, or not; typically the 480 line format
was not interlaced but there might be high resolution modes that were. The reason was to
deal with bandwidth limitations.
Flat panel displays normally support a pile of input formats, though only the
"native" format (the actual line count matching the display hardware) is
directly handled, all the others involve reformatting to the native format. That
reformatting generally results in some loss of display quality, how much depends on how
well the relevant hardware is designed. And interlaced formats are often supported not
just for the VGA input (if there is one) but also for DVI/HDMI inputs. To get the
accurate answer you have to check the specification sheet.

I think I tried a game on a flatscreen, and had issues. I don't know if it applies
to the radio shack Color Computer, the interest of the original poster.
many games and entry pcs with old style tv analog format, don't interlace, and tube
TVs nearly all (except maybe a few late model high end ones?) are fine with that, but I
seem to recall that most or all digital/flat screen can't deal with non-interlace.
