[Coco] Howto for Altera DE1?

[Lothan]

Wouldn't it be better to use a dynamically-sized array or perhaps 
List<DWDiskSector> than allocating the maximum theoretical disk size for 
each image? If you use an array, you'll have to calculate the size of the 
array prior to allocation. If you use a List<DWDiskSector>, the array can be 
allocated on the fly as you add items to the list.
