Hi Bom,

the answer is NO 8O

The Grey Matter E! card runs its own firmware where v1.20 seems to be the latest version. The card wouldn't accept any other firmware which is not specially dedicated to be used with this E! card! :o

If you want to run your DX7II/FD on firmware 1.9 (which is from Yamaha) you have to take out the entire E! card thing :o , put the eprom into the socket (labeled IC23) and you should be ready to go... :wink:

Hi.

I just aquired a non-working DX7-IID (a change of battery should do the trick)

And so I figured since I've already taken this puppy apart I might as well update the firmware, would it be possible for one of you sweet boys to share the 1.9 bin file with me?


Thank you :)

Does anyone have the changelog for this DX7ii firmware? What is to be gained with 1.9 if you're on something older. My DX7iiFD is quite stable, I think I crashed it once in 31 years. So I wonder if it's worth it.

I've come across only of one of the changelogs for the DX7IID/FD yet. The only 'Service News' I have is the Bulletin 419: DX7II TEST PROGRAM SPECIFICATIONS which describes the steps of the built-in test program 8O

Does anybody know where I can get the DX7II D firmware 1.9 file? I've got an EPROM programmer and also some 27512 available but I can't find the file.
Thanks in advance.
Regards, Michael

Hello to the Yamaha Musicians community. After looking for years for one, this Christmas I became the proud owner of a DX7 II-FD. So if any of you could share the file for the 1.9 FW I will greatly appreciate it. As a general question, the DX21 can be upgraded too? Thanks a lot and greetings from Mexico.

I think the latest DX21 is v1.5.

As far as I'm aware: that's correct.

Check out this firmware oddity: Version 1.A?
https://www.ebay.com/itm/YAMAHA-DX7II-F ... SwB4ZfpAar

He claims it's AFTER v1.9. Too expensive for my blood, but wondering if anyone has seen or used this one.

Never heard about this firmware version before - but I'm able to 'cheat' such a version number. That's easy if you're a little experienced on burning eproms... Maybe he used such 'cheat', who knows... :wink:

And yes, waaaay to expensive, as is his offer for the DX7 Mk.I Special Edition Rom. Maybe one should ask him if he's officially allowed by Yamaha to sell those copys - which I doubt!

That's what I'm thinking too. Did Yamaha ever use letters?? I guess until someone does a comparison we won't know... Maybe we should ask him for a photo of the FUNC+16+32 screen**. Mind you, that could be faked too.

** - Sorry I don't know the key combination for DIAGNOSTICS off the top of my head for this synth. I only see a faked boot screen.
