Got te download for the DOS and while I can mount it as either Drive 1 or
2, trying to get a directory it returns an IV ERROR (Invalid Directory).
Decided to snoop around the SDC and found that any VDK image not 184332
bytes long won't display a DIR properly, the DP50.VDK file is listed as
having 183576 bytes.

Will try the CoCo based firmware update method tomorrow...
