Yes, you're right. Hercules and CGA can coexist. I believe it wasn't uncommon back then for a no-name PC clone system with
on-board CGA to get "upgraded" at some point with a Hercules/Printer combo card as a secondary display device (or vice versa).
In DOS, switching to one of them was (later) possible with the MODE utility (MODE CO40, CO80 and MONO).
It allowed to select the active device for text ouput on the console (CON). MODE treaded Hercules pretty much
like old MDA in this respect, I believe.
I recall, our old copy of AutoCAD also supported the HGC/MDA as a dedicated display for the menu and status information..
Not sure, though, if it utilized Hercules' in half-page mode or if it only wrote some text in MDA-fashion.
This is also a common way to free up some additional conventional memory if a non-monochrome monitor is used;
you can usually safely remap that area and reclaim it as free space.
Yes, I heard so. In fact, I tried myself to get that working not so long ago. 😅

Cool. 😎 I have a soft spot for yellow/amber screens (and orange plasmas), too, as can be see in my channel.
Anyway, If you like amber screens, have a look at this blog entry about "Mobile Data Terminals".
