Abstract
A data processing apparatus is provided with a keyboard and a programmable read-only memory, for example of EPROM type, for durably preserving data which define the manner of operation of the apparatus. A programming circuit connected to the apparatus allows a new memory of the same type to be programmed either by automatic recording of data contained in the original EPROM memory, or by data entered by means of the keyboard in order to make available a new read-only memory provided with data modified relative to the data of the original memory.
