[Coco] Need help (of course)

What is normally done on TRS-80 Disk drives is that you jumper DS0 and DS1 
on every drive. Put the terminator in the Drive 0:, and remove it on all 
other drives.

Then, you remove the pins from the edge connector on the drive cable for the 
unused drive selects, causing each connector to select only one position 
with drive 0: being the furthest from the controller. You can have 4 single 
sided drives this way. If you want to use double sided drives on a Coco, I 
think you have to jumper ds3 to the side select pin with a wire in both 
drives, and you can only have two drives in DEB. OS-9 might let you have 3 
double-sided drives, but someone else would have to tell you.
