A Rough History of the Development of the Electronic Computer
─────────────────────────────────────────────────────────────
The earliest electrical logic machines were huge, taking up many
floors of large buildings, and almost required their own power
stations for their electrical needs.
To run a programme, instead of the modern magnetic disk, these
beasts had reams of paper with holes punched in them in
strategic places that worked in much the same way that a music
box "pin wheel" plucks the metal bars in a miniature piano.
Recording the information? No single key press to save to a disk
but humans with pencil and paper.
Inputing information involved working directly with binary code
from a bank of crude switches that controlled thousands of
electrical relays, diverting signal current down kilometers of
cables.
