[Coco] Drivewire on an original Raspberry Pi

[Walter ZAMBOTTI]

This will make you all laugh.

The only reason I persisted in getting it going on ARM Linux (Odroid) 
was because when I read the post DW4 was working on the CoCo-PI I 
assumed the GUI was also working and I thought to myself if someone can 
do it on the PI then I can do it on the Odroid.

This is not the first time I have tried.

Funny how a misconception can be the impetus for success!
