NEED HELP need FANUC OMC 900 parameters toyosk

I have a Toyosk with a fanuc omc and Mitsubishi plc. It lost everything and I cant make out the option parameters in the book so looking for someone that can provide me with some that might work. Machine is from 1995 and manufacture says they don't have them. We have no other Fanuc omc's. Our oldest other than this Fanuc omc is powermate d's and f's. We mainly use 18'i,21i,31i ect ect. When I try our other machines option parameters in the 900's it makes it so I cant put in anything in the pmc parameters. Any help would be great.
