[Coco] Level3 and Drivewire may not work

[Brett Gordon]

If the DW module in question just masks interrupts during it's
transactions (the uber-lock), I can't logically see any serious
problem with splitting it into separate SCF and a RBF modules.  I
think DW also handles the reading the PC's Clock too... how would that
fit into things?

I have converted some of them to be compatible in VCC, but not all.  I can’t figure out why on some of them.  Work perfect in raw Disk basic, but not HDBDos.
