Here is some version info:

No, it doesn't, it just goes through the tests, but no ROM version number.

All I know is that the chip has the markings YAMAHA TG11461, YA3128, C86-3L1 (that is, I assume, IC 14 is the ROM).

But as I now know that the behaviour is not really a defect in my machine, but more a sign that it is (mostly) in its original state, I don't see a reason to change that. I don't need to dump from DX7, and even if, I now know a few workarounds.

Except for, of course, if there are any reasons for me, if there is something a newer firmware does better, which is actually important for me. I'm not aware of anything right now.

Cheer, Florian

Does Function+16+32 tell you the ROM version? If it's an old one then I agree with an updated ROM. I wouldn't add a complex expansion until things are well understood in the vanilla unit.

Good luck! Replacing the ROM chip with something newer (either stock 1.8 or the french superMax board on ebay) sounds like the way to go.

So, I was barking up the wrong tree, the DX7 was not (well...) to blame, it worked exactly to spec. Great to know.

groups.io blocks the display of email addresses in messages - for spam prevention, I guess.

You could upload any ROM images to the Files section though.? There's already a DX7 folder, so maybe put them in there.? Look for Files on the menu on the left side of each Groups page.

There are a lot of files that ought to be in a folder too... You might want to look through those.? I see a couple of SER7 documents.
