You crazy kids, 80 colums?!? Pure non-sense!
In my day, we used primitive torches to burn binary dots onto chemically treated goat skin. We then spent our evenings around the fire decoding the input, using sea shells with sand in them for each byte. By morning, each shell was aligned and I could read the ASCII code out loud to debug my code.
For input, I used to craft copper drums out of ore and fuse the privative hand made capacitors to each in a precise alignment. Then we entered in the machine code by charging each capacitor we wanted with a simple clay jar battery and hand crafted wire mesh.
We did not have any electricity back then, so we had to hand crank the drums at a consistent 30 RPM as to synchronize it with the 60Hz clock of our main "Computer."
