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.
