I used Novell DOS 7 back in its day and squeezed > 70 MB on my 50 MB hard disk drive thanks to its Stacker disk compression feature. I remember it coming in a flashy red colored box. It also supported to move most drivers into extended memory to have much more conventional memory available on 386 machines. However, most cutting edge games used DOS protected mode extenders already, so for gaming you couldn’t use that feature.
Great times, anyways. ;)

And then there's PDOS (public domain operating system): https://www.pdos.org/

I remember a couple of friends using DR DOS in the 1980s. There seemed to be a disagreement about whether to pronounce it as /di ɑɹ/ or "doctor". (I realize it was named after a company and not after a doctor, so the former is more etymologically faithful.) Was there a standard among the creators or the user community?

Digital Research DOS. That's what I called it.

> DR DOS® 9.0 is a faithful clean-room reimplementation

If this company now owns DR DOS, why do they need to do a clean-room reimplementation?
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.

I think they only acquired the trademark, not the source code. But I‘m not sure.

I was a DR-DOS 6.0 user and it was great, 7.0 seemed to be worse. But by then I had moved to Coherent then Linux when MW closed down.
I will need to give DR-DOS a try.
