Err, I expect that that was RSTS-11 in June, 1970, not RSTS-E. Since RSTS-11
(which I learned to program on; happy memories :-) was a BASIC-PLUS only
system, and ran on a PDP-11/20, I suspect it was a fairly different operating
system (although no doubt it's BASIC-PLUS interpreter was ported to RSTS-E).

I think RSTS/E needed the -11/45, introduced around June 1972; sources
give 1973 for RSTS/E.
