IBM selectric typewriter
Instead of Bars stricking paper, IBM introduced a ball ,that resembled a golf ball, was used instead of bars. This prevented typewriter jams and allowed for much faster typing instead of fairly slow typing. These were available in many colors -
First early protoypes of computer keyboards
The type of keyboards used in this time were advance compared to older iterations of the device. This one used filiments not unlike the ones you would find in Holiday decorations, to send electrical signals to a very early, simple computer that could tell what you were typing. Although a good idea on paper, the filiments often broke and were very difficult to fix, on top of that if the user typed too fast instead of picking up different letters, it would pick up many of the same letters. -
Modern keyboards
Modern keyboards work very similarly to the ones in the early 1970s, but instead filiments, modern keyboards use electrical switches not dissimilar from a light switch, press button get input.
a few microprocessers later and you have a modern keyboard!
