Dave,
that's only the internal Bosch p/n for the EPROM. It is of no relevance
to your recearch.

What you need to do is read what's written on the PAPER stick-on label
that coveres the EEPROM's glass window for the UV eraser. Hopefully it
will contain the hexadecimal checksum number. It will be sort of a
signature of a particular software burnt into the chip. I am sure a few
of us on the list will be able to help you identify it.
