I have a few left over circuit boards available if anyone wants one. Send me an email if you are interested. Note these require mounting some tricky SMCs on them.
This video below shows the interface in action with my latest Teletype, the Model 26. The software I am running is BaudotRSS (also from John Nagel) printing out today's news headlines.
The interface and software also work on my Model 15 as well.
