it uses a 24LC32B
Is it likely or unlikely that if I changed it to a 128, that the
firmware on
the ucontroller would limit the running to 32K/ not work at all or allow
running out to 128K ?
As serial linkage I'm hoping it would not be limited

If it can't address more memory, you could use two (or three) memory
chips with a switch to select which one to use.

What would be the minimum number of lines that would need switching ?
Could you leave A0,A1,SDA paralleled and just switch SCL and WP?
