[YamahaDX] DX7 EPROMS, BBQ or Vinegar

[[e-mail] [YamahaDX]]

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 !

Congratulations!

Replacement Eprom should work.

Enclosed is V 1.8, which seems to be the last one


All the best!

I have one which is V 1.9.



Is this the same application?

It has 65536 bytes, so it is for DX7 II D/FD. Check it in hex editor, you will see functions for this instruments.

DX7 OS has 16384 bytes.
