Good point, but the OS I was referring to is RISC OS, *the* original
ARM OS and it has only ever run on ARM and nothing else.
Nobody is making PDP-7s any more, are they? :-)
I think the first C-based Unix was 4th edition. Are there any new PDP-11s?
If that makes my point any clearer?
Yes, that does clarify things, thank you.
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?
