Abstract

Abstract An automatic film processor having control circuitry including a microprocessor and an electrically alterable programmable read-only memory (EAPROM) with a stored main program for control of the processor, has an auxiliary read-only memory (ROM) containing a bootstrap program including instructions for reprogramming the EAPROM using addresses and data from a disk drive or RS232 port. Reprogramming occurs in response to manual or automatic setting of a switch, without physically removing or replacing the EAPROM.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 150 words
In apparatus for the automatic processing of exposed photosensitive media, said apparatus having means for automatically transporting said media from a feed point along a path through developer, fixer, wash and dryer stations and control circuitry including a microprocessor and a programmable read-only memory associated with said microprocessor to provide stored program information thereto for controlling said processor operations, a method of updating said stored program information without removal of said programmable read-only memory, comprising the steps of: switching said control circuitry from a normal mode in which said microprocessor is connected to receive program information from said programmable read-only memory, to a programming mode in which said microprocessor is connected to receive program information from an auxiliary read-only memory; and reprogramming said programmable read-only memory by said microprocessor acting in response to program information from said auxiliary read-only memory using address and data information obtained from an external source.
Claim 2
Dependent Claim 150 words
