RCA/Sperry Univac had reasonably large scale time sharing systems running basic, FORTRAN, apl, algol and 360-compatible assembly language. They had both physical and logical I/O APIs and supported vm to both disks and drums. Fill in the rest of the old time computer room as you’d like. Did a chess program and various other things in assembly, wrote the required Star Trek game in basic etc. As they provided the source code to the OS, even messed around with changing things like adding 2-step logins and other hacks. Basically, that decade saw the continuation and growth of the hacker culture that started in the early 60’s on trivially small machines (google spacewar). As there were no small machines, things were more social / collaborative than now out of necessity. And yeah, the hardware is bazillion times faster but the software less so as code bloat is real.
