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
