Vintage Synth Repair

Hi Miguel 

Many years ago, I had a DX7 and put an expansion card to get 4
internal banks. 
to install the card, I'd to remove the genuine IC ROM from the DX.
I sold the keyboard but I think I still have these genuine ROMs.
If you need them, tell me, I'll look for them. Just be patient and
make a pray to help me to find them easily !
