I'm quite positive that Steve knows that :-)

Anyway, a somewhat different but related question I'm trying to get
an answer to is:
  How does the C128 ROM detect if the drive is Burst-capable?

I downloaded the ROM and I am commenting the disassembly, but I
would really only need to know when does the drive send that one
fast serial byte which flags it as burst-capable? So, if anyone
already has the answer, give it to me now :-)

"Actually, the temperature appears to be quite moderate."
