The early ARM machines didn’t really make it out of the U.K. I had some early Acorn/ARM stuff in 1988. It was by far the most advanced bit of kit at the time. Literally smoked everything and did so for a number of years afterwards.

They even did a line of unix workstations!
Nice video on the matter here from 1987: https://youtu.be/hrj-EEnsacQ
