: I, too have a similar need, and turned to this newsgroup for the express : purpose of asking about pin numbers! Tell us about your experience of 10 : years ago. I've got plenty of experience in making cables and the right : tools, but just need the pin numbers if in fact it is doable.
The following is a reply I received when I asked this exact same AUI <-> AUI "null modem" question a while back. (I forget which group I asked on...)
I **DID NOT** try out this wiring diagram, as the need evaporated before I had a chance to try it out. (I found some BNC transceivers laying around. :-)
**Try this at your own risk.**
