I'm assuming that's a GE Fanuc 90-30 CPU331 since that's what you've talked about in the past.
Part number 44A731232 will get you the latest revision firmware. You'll have to remove the circuit board from the plastic case, pry off the old EPROM chip and replace it with the new one. You'll lose the ladder logic program in the process, so be sure to back it up before making the change.
