That's good.

That's expected. d64copy does not know anything about a 2031.

That's a really big pity, as the 2031 is the drive that is most similar
to a 1540/1541, and it should be relativly easy to get it working.
Unfortunately, I never owned one.

That's interesting. I would have expected a footprint of FFFF, at least
according to the ROM I have.

The footprint is the contents at $FF40, and in the only ROM dump I have
of a 2031, this is AAAA - identical to a 1540, and I would have expected
cbmctrl to detect it as a 1540.

Can you please try if you can dump the ROM and send it to me?

$ cbmctrl download 8 0xc000 0x4000 rom2031.dump

and send me the file rom2031.dump. It should be 16384 byte if everything
worked out fine.

If the file is less then 16384 byte, it might help if you repeat this
process. Additionally, I would be interested in ALL results you got with
this command, as it can tell me if and what problems you had.

Oh, and don't be surprised, the command can take some minutes to finish!


Can you read out the (physical) marking of the ROM chips, too? It is
written on top of the ROM chips. The only ones I know are 901484-03 (for
$C000-$DFFF) and 901484-05 (for $E000-$FFFF).

Regards,
Spiro.
