ca83431e54 Fixed: Scc is a byte operation. 
It was, until now, post-incrementing and pre-decrementing registers other than A7 incorrectly.

df56e6fe53 Fixed: the sector number also goes into sector bodies. 
Also the checksum is written in the other order, and the final byte of data isn't output.

bde975a3b9 Possibly mights the tiniest bit of headway with 'the IWM'. 
I'm now pretty sure that my 3.5" drive, which for now is implemented in the IWM (yuck) is just responding to queries incorrectly.
