I don't have one in front of me but I am sure one is coming. A good old simple DX7.

I see the one time writable TMM24128 is used and I am curious will a 27C128 work as a firmware replacement?

Also In the files there is a DX7 firmware bin file but no version to be found. Does anyone know what the last version was for a stock DX7? and where can it be had.

Thanks All !
