Around a little longer than that
Seconded, yay for RSTS/E, though it was at least there until 85 since a friend and I wrote the library book management program for it (him doing the majority). Not just BASIC, but BASIC-PLUS-2, whose "foo if bar" qualifier inspired the same Perl syntax and whose code grew large enough to require overlays and the TKB Task Builder to produce the executable, taking hugely longer and hammering the system something rotten during each build. Mostly used FED as editor (local homebrew?) though occasionally TECO. (I later had a TECO version on Ultrix and later yet used DEC's MIPS->Alpha binary converter to have it running on Digital UNIX years after). All that (30 concurrent users at times) in 128KB (or was it 256KB?) of memory. A Systime (*cough*) rather than a PDP. Still have a mini-magtape backup of the code somewhere. Taught by both Neil Sheldon and Alan Pickwick whose ICL 1902T in the chemistry lab has also been commented on in the The Reg, IIRC. Being taught by those two and "sysopping" both those machines was a formative part of my education and current career.
