@p @xianc78 >DOSBox solves enough of my problems.
Yes, even if you intend to surrender your freedom to proprietary games, DOSBox usually offers a better experience.

>MIT.
Which one? MIT released many licenses.

Just slapping a copy of MIT expat into a repo doesn't really mean anything legally.

>it might be difficult to port even free software written for DOS to a more recent operating system.
I reckon it'll be easier to port DOS C free software than to get sepples to compile.

>Free software written for DOS does exist.
Please provide examples.

>Some people use DOS as a bootloader!
I don't see why you would do that instead of using the superior GNU GRUB.

>I don't see any issues with using the computer to investigate older computers and older software
There is mere investigation (you'll soon realize garbage it is and stop using it) and there is surrendering freedom to proprietary software.
