[Coco] CoCo 2 + CoCo SDC problem

[Tri-City-Maniac]

Hi,

i used the CoCo SDC interface for my Dragons so far and it worked very well.

I've a CoCo 2 as well, so i tried to run the interface with this one.

What i did:

- changed the Dragon DIP switch to off (all switched are "down" now) and 
removed the jumper from the DRQ pins
- plugged the interface in and ...

  ... i only got the normal CoCo 2 basic screen.

After that i put the jumper to AUTO and i only got a white screen and 
nothing happens.

Well, i think, that i should get at least the SDC  boot screen ...

Who could help?

Thanks.

Cheers

Tom
