Hi,
For some, this might bring back memories. Back in about 1989, I used a 386 machine with, I think, a Trident and Hercules video cards. I used to send HelpPC (https://stanislavs.org/helppc/) output to the Hercules card and to a monochrome monitor.
Now that I think about it, I think there were better ways to do this by using something like DESQview (https://winworldpc.com/product/desqview/1x). But I didn't know any really serious programmers back then.
Anyway, I was playing around with 86Box (https://github.com/86Box), and found that I could add a second video card. So I installed DOS 6.2, (I think I used IBM DOS 4.0 back then) added the second video card and it worked like a charm.
The only problem with 86Box is that the networking doesn't work on Linux hosts.
Anyway, I found it interesting.
Regards,
Craig
