Abstract: A computer system with an internal operating system located in ROM is initialized in that operating system but can also automatically be directly initialized in an operating system of choice such as one located on an external memory, that is, a diskette or fixed disk. The computer system may also automatically be directly initialized in an application running under the internal operating system and, if desired, initialization may automatically directly include a customized version of the internal operating system. These customizing features are obtained through a customization word located in permanent read/write memory.

Abstract: An electronic typewriter or other keyboard entry display device may have a voice or audio prompt option incorporated therein. The option provides for the operator to record a series of commands to position the print point as desired and then to code a series of characters spelling the word or words to be vocalized as a prompt. The recorded commands and the prompt may subsequently be played back to position the print point at a desired position on the page and the prompt vocalized to instruct the operator the nature of the entry for that position.
