Norman Wilson scripsit:
I think the P/OS, the standard OS shipped with those
systems, was a
hacked-up RSX-11M.
Several sources agree that it was, and speak of a menu shell.
I don't know whether there was ever an RT-11 for
the Pro.
<http://www.vintage-computer.com/dec_pro_350.shtml> claims that
RT-11 ran: whether stock or modified, the page doesn't say. This
is confirmed by a squib in InfoWorld 6:23 (June 4, 1984) on p. 84
<http://books.google.com/books?id=vi4EAAAAMBAJ&pg=PA84>, which also
speaks of a V7 derivative called VII-M. Venix 2.0 (aka System III) was
definitely available.
