94 - 97 Accord radio anti theft code

I bought a '94 - '97 Honda Accord AM/FM/cassette Radio from ebay. The radio was salvaged from a vehicle long since crushed. After hookup to the radio wiring harness the radio displays the error code "COdE", which generally requires a VIN specific unlocking code. As the vehicle was crushed years ago, all I have are the radio's model # 39100-sv-A000 and its serial number is 93C968642.

Can someone give me the unlocking code for this particular radio having this serial number 93C968642 ?

I might note that disconnecting the harness and reconnecting and powering up again with #1 and #6 station preset buttons simultaneously depressed does NOT reveal any code or serial number.

I also might note that the factory radios of this vintage on the Accords have a terrible track record of poor radio chassis solder connections. I have replaced the original radio twice now; each developed a temperature related circuit board intermittant failure. For example on a summer day, the radio might break in and out. Also if I twist firmly the chassis in my hand, I can bring the radio back to working condition (until I release the twisting; then it fails again). Visual inspection of the chassis reveals no obvious solder breaks or off-sheen solder points. The broken solder connection is either hidden or too small to see without a magnifying lens.

Thanks in advance for the code or your suggestions.
