ABSTRACT:
A spell verification method and apparatus which comprises inputting characters and operational modes by keystrokes, printing input characters, providing a read only memory having plural dictionaries with spelling information, each dictionary including different but complementary dictionary entries, and executing program steps by a single chip microprocessor which includes an internal memory for storing program steps to control functions of the printer via a dedicated interface port and to control a spell verification function of the electronic typewriter. The single chip microprocessor further includes a detector for detecting whether the read only memory is connected to a dedicated interface port of the single chip microprocessor. Upon determining the status of the connection, the single chip microprocessor either enables or disables the spell verification function.
