I had a RAM parity error on the 15M controls and lost the entire set up of the KV-1000. I had a hard copy of the parameters, timer/counters, and keep relays, but do not have the ladder program. I contacted Kuraki and they talked to Kuraki Japan but were not able to locate any copies of the ladder. Any assistance would be greatly appreciated. A great machine that is currently a big brick.

The ladder on a 15M is almost always burned onto ROM chips that are in sockets 001 and 002 on the PMC board (probably an A16B-2201-0371). Having a RAM parity alarm should not cause the ladder to be lost. What is happening that indicates the ladder is gone?
