What happens if the FV-1 powers up in external memory mode, but there's no EEPROM connected?

I'm just curious, I have no application for this, so no other info to give or anything. I was just pondering it. Obviously, it can't load an external program in this case, so does it default to the respective internal program, or does the FV1 get loaded with a blank program, or will it be damaged?

It will go through the motions of loading a program and basically nothing will happen, it really can't tell there is no EEPROM attached as there is an internal pull-up on SDA so it will load all 1's.
