That's amazing given that "high-speed" reel-to-reel paper tape readers
and very much faster paper tape punches were in common use by that
time. Even the fairly primitive (no RAM and no semiconductors)
pre-FORTRAN Bendix G-15 came equipped with both of these paper tape
devices - and even then there was a mag tape option. I'd have expected
better of Lockheed.

The overall chain of load-input/execute/output sequences is still
pretty much the same - it's just that the media and the logic have
become faster and larger.
