Yes, that does clarify things, thank you.
Ah, good. :-)
Looking as a naive researcher, Wikipedia doesn't have any information on
the ARM processor before 1981 or RiscOS before 1987. Do you have a source
for your date of the late '70s?
But manifestly not enough. It *is* really stretching my point, though.
The ARM was expressly designed as a sort of 32-bit 6502. It was
Acorn's successor to their BBC Micro range of 6502 machines. The BBC
Micro came after the Acorn Atom, and that after the Acorn System 1, 2
& 3.

The BBC Micro OS was called MOS -- Machine Operating System. It was
not Arm-native because Arm didn't exist yet. But Arthur and RISC OS
(Arthur 2) are based on a command-line-only core OS which is a 32-bit
version of MOS.
(There was also a single model of machine with a 16-bit version for
the 65C816, the Acorn Communicator.)
I am being cross-examined on a flippant throwaway comment, but it's
fair and I brought it upon myself. :`D
