You will need to be more precise with your questions. As asked, "I've forgotten 
though how to mount disk images under the CoCo BASIC", the question is meaningless.
A real Coco does not use disk images but real floppies, 5.25 or 3.5". Emulators 
running on advanced PCs use images and mounting of the disk images is specific 
to individual emulators.

I think you want to know how to mount a .dsk image in Drivewire but I can't be 
sure. If that is what you meant, just start the Drivewire server and click on 
the slots in the Drivewire image and a window should appear asking for the 
location of a .dsk, .or9, or .vhd image.
If you are asking about mounting disk images with the Altera / TerASIC DE1 
board, I haven't a clue.
