Hello;
Real Men use punched paper tape to store programs and load the boot
block, after toggling
its binary location on the system console register :) The Gods Who Walk
Among Us program in machine
code by toggling it in at the console.
(I still have some punched paper tape somewhere. I remember feeling
impressed when I graduated to
punched cards. They didn't tend to crack if you had a string of all bits
set to one.)
On the other hand, I did tens of thousands of lines of code on IBM
punched cards and I never
once recall a bug caused by a chad, hanging or otherwise.
Regards
