Before any field use, Maria insisted on a rigorous validation protocol. Jun prepared a test rig with a spare PMC cabinet and a configurable I/O simulator. He loaded the original EPROM, exercised sequences, and recorded outputs. Then he applied the converted image and repeated the tests. The results were compared with automated scripts. When everything matched within expected tolerances, they documented the steps and stored both images in the repository with signatures and release notes.

As Fanuc CNC machines age, the original EPROM chips are prone to "ROM failures" due to data degradation or parity errors after 20+ years. If this data is lost, restoring the machine is difficult and expensive, as most manufacturers no longer support these older chips. Before any field use, Maria insisted on a
: Success often depends on having a high-quality EPROM reader (like a Wellon or Xeltek) to get a clean raw binary file first. Then he applied the converted image and repeated the tests
