Another fun fact you might want to add, is that Apple, when they came to a crossroads after the failure of trying to invent a NexGen operating system in Copeland, had to decide whether to buy BeOS or to buy the entire company NeXT in order to get NeXTSTEP. They decided to acquire NeXT, along with NeXTSTEP and Steve Jobs (the then CEO of NeXT)and to hire him on as interim CEO of Apple, and, eventually the CEO. And that’s how Apple got Steve Jobs back as CEO.  technically, it was a huge gambit that Steve Jobs arranged while he was still the CEO of NeXT and it saved both companies from complete ruin, particularly when he arranged a financing deal with Microsoft year later. 
I think I still have a couple versions of Rhapsody on CD somewhere. It was a really wild mashup of OPENSTEP with MacOS 8 styling. I’m not sure if I have the x86 version, but if so, it might be fun to see if it’ll run in a modern virtual machine. I’m also not sure if I kept media for a “Yellow Box” install, when part of Apple’s strategy was to have its APIs run on Windows NT to allow for cross-platform apps.
*NeXTSTEP. And the NS object calls are part of the Objective-C programming language it was built with.
Oops yeah, corrected in my post

I have a version of it running in a VM somewhere on an archived Drive someplace. It was very interesting to be sure.
