Subject: [vintagesynthrepair] DX7 Special Edition Eprom

Hi all,

Does anyone have the binary image of the DX7 special edition Eprom.

I have a DX7 here which needs a battery change but no RAM cartridge to save the presets to.

There is also no tape save option, but the special edition ROM has Sysex dump as an option.

I could burn a ROM quickly and get the job done.

The other option? write down the parameter list for 32 presets and then manually program the whole thing back in again.

Not something I would look forward to!

Regards

John
