I have a Fanuc 0M-A with 8K memory. I am fairly new to this, but have already exceeded this limitation and cannot load my part file ( I want to upgrade this memory and see that there are 2 empty slots 2H, 3H, 2L, 3L. Can anyone tell me if they are the same chips that is in slots 1H and 1L? I have D43256C-12L in these first slots.
