Radio/Stereo: - Radio Codes Please

Hi all and Healthy & happy New Year.

My Radio has died so I unearthed another CR702 from the archive from a donor unknown AND SO the ugly code reared it's even uglier head !

Label is faded so can't establish the serial number and ask normal means but after searching the diode setting of the code on this model was found, have opened and recorded the diode absent slots which are D7, D9, D10 & D12.
Being vaguely conversant with BCD coding I tried the obvious without success, further searching found a bit decode (I think from a CR708) which resulted in a code of 2513, no go again.
Further searching tonight gave an Australian Geocities site of OZBRICK850, which appears to have been kidnapped by Aliens and near the start of this thread a couple of ZIP files for decoders, which seem to have become unzipped.
PLEASE can someone point me at somewhere that gives the bit order for the 702 before keyboard Covid gets me ?? TIA Rick in freezing Broadland
