There appears to be a boat load of articles for the Model 33, including a commercially available board. Not so for the 15. I have attached a zip file with what I have for a USB interface, but I don't think you will get away without building something.

you can also look here: https://www.aetherltd.com/connecting.html

The zip file was created with 7zip.

Chris,

  I'd like to know the same thing.
I don't know of any current plans available but if I were to cook something up myself
I'd consider using an Arduino.
This requires programming in C. and building some electronic interface to match the signal levels.
If someone else has already done it I'd rather not reinvent the wheel.
Others on here are way more qualified to answer this than I.
This is something I might attempt down the road but not in the near term.

It's my ultimate goal to hook up a model 15 to my weather PC (windows)...  ive seen some ideas on say rs232 interfaces where one has to build a board one I dont build boards next the plans ove seen use obsolete parts...  what's the best or easiest way to accomplish this... USB would be great...
