System for updating software in automatic film processor.

摘要

An automatic film processor having control circuitry including a microprocessor (43) and a plurality of electrically alterable programmable read-only memory (EEPROM) elements (44) for respectively storing main operating program and language codes for control of said processor, has a non-volatile read-only memory (ROM) element (45) 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 (48). Initialization or reprogramming occurs without the necessity for physically removing or replacing the ROMs, and in response to flags set by software. <IMAGE>
