ABSTRACT:
An automatic film processor having control circuitry including a microprocessor and a plurality of electrically alterable programmable read-only memory (EAPROM) elements for respectively storing main operating program and language codes for control of the processor, has a non-volatile read-only memory (ROM) element containing a bootstrap program including instructions for reprogramming the main program and language ROMs, using addresses and code downloaded from a laptop computer using an RS232 interface. Initialization or reprogramming occurs without the necessity for physically removing or replacing the ROMs, and in response to flags set by software.
