Yes. I did it in the 1980s (in large part because the VT220 had 20mA
built-in). I don't remember the terminal settings, though.
What did not work was the VTEDIT TECO macro. There's something
inexact about the VT52 emulation in a VT220. The cheapest solution at
the time was to get a real VT52 (about $50 to buy and $30 to ship).
That's what I did. If you are just doing rather ordinary things with
OS/8, a VT220 should
work just fine.
I never saw any problems at all with anything, using a VT100 or more
modern, with OS/8. Most programs expected it to be in VT52-mode, though.

I have no datapoints for those other terminals, but I'd be happy to
hear your results. They may work just fine. I only ever tested the
VT220 specifically. If I can ever carve out some PDP-8 time, I want
to run some VTEDIT tests now that I have lots of terminals lying
around. Back in the day, I only had a current-loop console cable, so
my choice of terminals was limited. Now, of course, I'd just whip up
a EIA cable, but then, I would have had to buy one.

I have a copy of OS/8 TECO that generates ANSI sequences for watch
mode, with a modified copy of VTEDIT that works with it.
It works fine with SIMH and PuTTY, but it'd be interesting to see if it
works with a real VT220.
