Hallo Martin,

IIRC a previous mail mentioned that a C900 sector had 512 bytes. A 
8250 sector has 256 bytes. Fortunately there is no hardware involved 
in setting these numbers, just software. So if you are interested in 
changing the ROMs of a 8250, I can give you the ASMs of both the 
Disk and Bus controller.
