Great times, anyways. ;)
The About page mentions some form of ownership but doesn’t address that.
> …DRI continuing to publish updates until their sale to Novell in 1991. … DR DOS would change hands from Novell to Caldera in 1996, and again from Caldera to DeviceLogics in 2002.
> In 2022, Whitehorn Ltd. Co. acquired DR DOS and began the process of clean-room re-implementing this historically significant operating system.
The front page only mentions a “legally unencumbered” reimplementation but not how their acquisition was encumbered.

The Wikipedia page describes some past legal troubles.
I'm too young to have used DR-DOS in anger (so I may be missing some key feature), but it seems like the entire point of DR-DOS would have been its source code legacy and accumulated feature set.
Here, my immediate question is why not FreeDOS? I'd guess it was system requirements, but according to the documentation DR-DOS 9 requires 2 MB of RAM minimum and a 386!!
This setup started WP5.1, a spread sheet -- I think Lotus123, and a graphics editing program. I think it switches using cntrl and the F keys, similar in feel to how a linux machine switches consoles.
I think at the time this was set up, only DR-DOS could do the task switching. I don't know if that is still true.
I will need to give DR-DOS a try.
