[Yaesu] Spare part for FT757GX

[Rees]

Hello to all the list,
this is my first post on the list also if I'm following the discussions 
from January.

This summer my FT757GX experienced an static discharge from the antenna.
Later I could find all damaged components and substitute all them 
excluded the main microprocessor Q67 wich is a MC146805G2P or SC82072P 
and is placed on the local unit board.

Actually all the stages of the RTX are working correctly again testing 
them singularly and simulating the functions of the broken processor.

I've asked to Yaesu for the part but their answer has been definitive, 
spare parts for the FT757GX are no more available and the firmware 
contained in the processor can't be found (I've also proposed them to 
give me the software stored in the processor to program a MC6805 by myself).

Somebody sad me that a couple of years ago on some list there was 
somebody from GB having some spare local units but this contact has been 
lost in the archives and no more found again.

So now I'm asking here if there is somebody out there who can help me:

.a spear part
.a unrecoverable broken RTX (or local unit board)
.a hint, a link or other suggestion

will be happily accepted.

Thank you very much for all what you can do for me.

Regards

Rees.

Is there somebody can help me in finding a spare IC?
