I have a Hitachi Seiki HC400 with a Fanuc 15M controller from around 1990. We recently had a RAM Parity Base (0) alarm. Once we corrected the issue we no longer have any of the machine tool builder macro programs in the machine(8000 or 9000 programs). I cannot change tools or pallets. If anyone has this information I would greatly appreciate it.

Thanks,
