All we had to do was load the load the 4th file from the card (which was the ladder). the trick was knowing how to load only the 4th file, I didn't have backup of any of NC params, etc..
To load the 4 file, we had to type M00001000 {READ} {EXECUTE}
bit 3 being the 4th file, bit 0 being the 1st file etc,
This is a list of the order of the backup files on a 21TA backup memory card (atleast it was me)
1= program
2= parameters and pitch
3= variables and offsets
4= Ladder
5= PMC
6 = operation history
7 = Macro executor ( requires 512K flash card)
