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:
- File Read
- File Write
Any leads would be appreciated!
