: What is RT-11?
:
It's an operating system for the Digital Equipment Corporation
PDP-11 series of 16-bit computers, that was popular mainly in
the 1970s and 80s, but still can be found today. It has a
similar look and feel to CP/M (which is no accident, since CP/M
was largely modeled after DEC operating systems like RT-11 and
TOPS-10). And of course what we now know as DOS (MS-DOS, PC-DOS)
descended from these same platforms, via CP/M.
For more information see:
http://www.columbia.edu/kermit/pdp11.html
As you can see there, RT-11 was one of many OS's for the PDP-11.
Others include DOS-11, RSX-11, RSTS/E, IAS, TSX+, P/OS, MUMPS,
and various forms of UNIX, mainly 2.x BSD. The PDP-11 newsgroup
is alt.sys.pdp11.
