75 years ago today, the University of Pennsylvania launched ENIAC, the
first non-classified programmable digital computer

preceded it, but the existence of that was kept secret for a few more
decades.) This was not a “stored-program” machine, at least not at
first: programming was initially done using patch cords and switches.
