I still have fond memories of RT-11 on the LSI-11/03 in university; twin 8" floppy drives.
The fun we had trying to shoehorn the DEC Fortran compiler, Linker and all the source files for Collosal Cave (or was it Adventure) onto two floppies. It was tight.
Plus we'd had to TYPE all the source code in; the DEC service guy wouldn't give us a machine readable version, just a printout!
