Me too, on the VIC-20.

It just had to turn it upside down!

I think something like the Commodore PET might qualify. Back in the day, I saw it used for everything from cash registers to accountants' workstations, but rarely for anything else.

I think that the original IBM PC was conceived and marketed as a business machine and only grew beyond that because of Microsoft's deep commitment to it as a platform and IBM's uncharacteristicly open specifications and design.

If not for that combination, the PC might never have left the office and most of us would have stuck with the companies who were actually breaking new ground, Apple and Commodore.

That doesn't surprise me. I have Haiku running in a VM, but haven't looked at it in 2 years, despite the fact I used BeOS as a daily driver back in the day.

Well, if you want "compile something unstable yourself," here is their official documentation for ARM64.

And here is someone's progress report on porting to RISC-V. They seem to have started in 2021, so maybe they were successful.
