Announced in 1980 the Selectric III typewriter expanded the keyboard to 92 characters.
Like its predecessor, the Correcting Selectric II, it has a correcting key that can erase the previously typed character.
This IBM 1052 was a console output printer for System/360 machines in the 1960s.
It was a cut-down Selectric I/O printer with no backspace and no tab. Keyboard input was provided by a separate keyboard.
The IBM Electronic Composer, announced in 1975, had the ability to store about 5,000 characters in its memory.
Users were able to work on two different documents, thanks to the machine having a main and alternate storage area.
The machine had two power switches, one for the typewriter portion and the second for the memory — which, if powered down, would result in the documents being lost.
The machine was an improvement over IBM's earlier Selectric Composer as the user could have the machine retype stored documents differently justified, rather than having to manually retype them.
