Decades ago, I worked for Thoroughbred Software and they owned an MAI BASIC Four computer. They are still in business.
https://www.thoroughbredsoftware.com/ . It had two removable disk drives, a system unit and a terminal.. Before I started working there, somebody went to make a backup, copying one disk to the other, and got the order wrong.
The history of Thoroughbred, as I was told, is that Concept Omega had created accounting software for the BASIC Four but wanted to sell it on other platforms. They could have rewritten the accounting software, but instead decided to clone the BASIC Four operating system which they named Thoroughbred.
I would be surprised if that BASIC Four ended up in the trash, but not very surprised.
