[Coco] NitrOS-9 on a 128k Coco-3

[Kandur]

Thanks Gene, 
I got the service manual and the jumper settings for that drive.
I think, I found the speed select jumper.

First I couldn?t boot OS-9 from a 3.5" drive, because it's drive select was
soldered to /d1, took it apart and managed to change it to /d0.

Heard, that you have a Coco running headless os-9 in the basement
and access it from a terminal (program?) from upstairs.
I used to have a similar setup with 4 VTUs connected to a Coco.
Would you mind to give me some pointers on how to set this up please?
