I am reminded of the (perhaps partly apocryphal) story of the IBM 1403
card reader's LOAD button which would get just one 80-column card image
into the 1410's core memory then start executing it. Unfortunately it
took 79 characters to simply get the next card read.. The boot loader
thus consisted of an initial section that accumulated one character of
the second stage per card, followed by a branch to the second-stage
image where a more useful boot loader now resided.
