I usually (but not entirely) avoided assembler and completely avoided machine code. Actually, the Univac 1108 wasn't a bad platform for the time: 48 bit arithmetic, an easy job control language, and the Univac dialect of Fortran didn't require character counting (the infamous "H" format) and actually rounded output, which was not universal.
