I do appreciate all of the information I have received so far
from the net in regards to the Color Computer Disk controllers.

I need to supply +12 volts to the controller chip in the 
cartridge, as the Coco 2 (unlike the Coco 1) does not do that.

The questions are:                                
1. To which pin on the controller chip do I apply the +12V?

and

2. I plan to take the +12v from the disk drive power supply, so
where is a good place to tap in?

I'm especially looking for information from people who have
done this mod already.

Thanks in advance!
