1 EEPROM for 2 interpreter chips
Hello,
is it possible to use the same EEPROM for 2 interpreter chips ? If i is possible, how can I choose the memory adress of the beginning of each program ?
Thank you in advance

You can't use one EEPROM for 2 interpreter chips. EEPROMs are cheap and small and it would slow down both interpreters if they had to share an EEPROM. The features of the I2C protocol that allow for multiple "masters" would also complicate the interpreter and it probably wouldn't fit anymore into the interpreter chip or PBasic features would have to be left out or simplified.
But I agree with Mike, trying to share "program" space is going to cause a timing nightmare
but on the other hand, if you'd like to share Data space to pass stuff between two masters it can be done
check out the PCA9541 2-to-1 I2C master selector.
