Hello, apologies that I cannot speak Deutch. I hope someone is able to understand what I am saying here. I found this thread and ran it through translate as I am also looking to reuse my Ricoh chips on my sp100e. The address pins being tied high are not a problem, I was able to read the contents of the using the chip address of 0x53 using an Arduino nano, outputting the memory over the serial monitor. My idea was to emulate the eeprom, but not being a programmer I realised it is beyond my ability.

I can post the details from an 'empty' chip, and one that has printed two pages if that will help, but they are not bin files, just a list of memory values. Let me know if this would help. Hi, sorry for the late reply and for posting in English.
This is the hex dump from the two chips, I think the empty chip was the 500 page one shipped with the printer. The full chip was third party from.
