Everything about the Omni Ultimate is designed around power and ruggedness.
On the occasion of ThinkPad's 25th birthday, we recall some of IBM's best known creations: from the Selectric typewriter to the IBM PC to the iconic laptop brand acquired by Lenovo in 2005.
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.
