[Coco] reading second side of real floppy disk on VCC

[Alex Evans]

The original DECB ROMS are set up for single sided drives and use the side
select alone to select drive 3, so DS1, DS2, DS3, and SS for drives 0-3.
With the patched ROMS that are commonly used it is DS1, DS2, DS1+SS,
DS2+SS. Assuming that VCC works properly with double sided drives for
things like OS-9, your issue may be that you are using the unpatched DECB
ROMS.
