Guys,

I've not seen anyone in this thread mention using the F11 key. That makes the VCC screen the size of 
your monitor. It also helps to then press F10 to get rid of the diagnostic line at the top of the 
screen.

Regards the VHDd drives, while there is a default .vhd drive size for MESS and VCC, the drive can be 
almost any size you want. You can have just an OS-9 drive or just a "Disk Basic" set of drives. You 
can have more sets of 256 Basic drives than you can possibly use.
All you need to do is change the value of the offset at $D938-$D93A. If it is $000000, then you 
could just have a set of 256 Disk Basic drives. You can make the largest possible OS-9 partition and 
still have Basic drives with an offset of $FD89FF.
If your offset starts as $000000, you can have about 104 sets of 256 Basic drives just by POKEing 
new offset values in intervals of $27600 manually or from a menu program.

The real value of using DW with VCC, MESS, or a real Coco is not different drives. It is the 
Internet, MIDI, or Printer access you obtain via Drivewire.
