Abstract: Disclosed herein are devices, methods and systems for integrating one or more applications and/or data sources to present a combined application employing data from the one or more applications and/or data sources. The one or more combined applications may employ data from the source applications and/or data sources, or be relevant to the context presented by the one or more combined applications.

Abstract: An apparatus for replacing an undesired code stored in a plurality of storage locations in read-only memory (ROM) with a replacement code. The replacement code, including a jump-back instruction to readdress the ROM, are programmed into an EEPROM. First and second storage locations store the beginning address of the undesired code and the beginning address of the replacement code, respectively. When the beginning address of the undesired code is generated by a program counter, a comparator generates a transfer signal. In response, the beginning address of the replacement code stored in the second storage location is transferred into the program counter. Each address of the replacement code is then sequenced by the program counter until a central processing unit recognizes the jump-back instruction. The central processing unit then readdresses the ROM in response to the jump-back instruction after the entire replacement code has been executed in place of the undesired code.
