IBM 6360 - interface help?

[Anders Nelson]

Hi again,

Is there anyone within ~100 miles of the NYC area with a working IBM
Displaywriter? I haven't found any more info on the signaling that goes
over the DB37 data cable, and I would like to use my portable logic
analyzer to sniff out some basics:

   - Boot
   - File Read
   - File Write

Any leads would be appreciated!
