Electronic Typewriters
The greatest change in the development of typewriters is the invention of the electronic typewriter. These were made with the use of plastic or metal daisy wheel, a dick that had letters on the outside, which replaced the type ball. Xerox produced electronic typewriters using the daisy wheel in 1981 in the Memorywriter product line. The electronic display allowed types to see errors and correct them before the text was printed. However, the daisy wheel was not always durable and often wore down. To solve this problem metal daisy wheels where invented. The electronic typewriter included word processors with either single line LCD displays or multiline CRT displays, built in editors, spelling and grammar check, a few kilobytes of RAM, and other external memory storage devices.
