Yes, it does (only I spelt it wrong, it's EMUTIL). The only gotcha is that the track numbers run from 0 on the D9060/D9090 and 1 on the floppy drives. > It should not be too hard to modify cbmconvert to support D9090 > images.

I'm not yet familiar with the detailed internals for the HD's but yes, I think so. As I said above the tracks go from 0-152 and the sector numbers run from 0-127 on the D9060 and 0-195 on the D9090.
