Did you not make a record of the parameters, even a hard copy list?
There is not that many on a 3T.
It is many years since I worked on a 3T, but IIRC there is 8 ROM ic's that may have to be transfered over to the new board.
I don't think this will be an option or parameter issue.
But if you are changing boards, you are either getting a different set of parameters or they all need re-loading.
Fanuc or Dan Fritz here on the zone should be able to confirm this.
