Typebar typewriters were still made up until at least the 1980s for electric typewriters, however, and are still made today for manual typewriters.A manual typewriter made today works in basically the same way as a manual typewriter did over 100 years ago!Therefore, old typewriters are still quite plentiful and hence most of them not very expensive.
It was somewhat similar to designs in the 1800s which had a single typing element.
People also still use typewriters today especially to fill in pre-printed forms or to type a quick envelope or label.
Finally, the QWERTY keyboard is used even on computers today - not because it is the most efficient pattern, but because it is the pattern everyone knows.
Front stroke meant you could see what was being typed as you typed.
QWERTY are the first 6 leters on a standard keyboard.
