By 1979 the LSI11 was available. And it's certainly
possibly to justify
that machine as a micro. Now, the LSI11 didn't (AFAIK) run RSX, but I
think it could have run one of the standalone multi-user BASICs (which
included its own OS).
The LSI-11/03 was available at least as early as 1975 (that's the
date on the earliest 'lsi11 pdp-11/03 processor handbook' that I
have).
