[Coco] Multipak and Drivewire

[Ron]

Hi Barry,

Your solution may have been the magic I've been looking for.  I've been 
able to access the real floppy drives and DriveWire independently, but 
not at the *same* time.  Your poke suggestion was the key.  I am now 
able to access both the really floppy drives and DriveWire system at the 
same time (using some DRIVE commands as well).

Thank you very much and to everyone else who offered me assistance. I 
really appreciate it!

-Ron
