Yamaha DX & TX Forum • Does Anyone Have Early DX7 ROM Versions?

I'm looking for early versions of the Yamaha DX7 Firmware ROM.

I have version v1.6 (IG114640), and version 1.8 (IG114680/90).
I'm looking for any of the earlier versions, like v1.7 (IG114670), or IG1146100/IG175700 + IG175750 (I'm not sure of the version number. This is only mentioned in service bulletin E-318).

Any help tracking these down would be greatly appreciated!
