2. “Cannot Be Read Better” – Three Possible Interpretations

2.1 Physical Readout Limitations

Early attempts to dump the TNS510’s ROM involved decapping the chip and using a microscope to read the mask ROM bits manually. This is error‑prone, destructive, and yields raw hex without structure. Several hobbyists reported: “We can read it, but not ‘better’ – meaning not in a well‑disassembled or annotated form.” The phrase thus reflects a desire for higher‑level understanding, not just raw bits.

In such cases, the problem may be a dying motherboard, a corrupted system EPROM, or a failing power supply. A technician can dump the system firmware and replace damaged hardware.
