I seem to remember that panadapter. Was it an Atlantic Electronics SM-1071, as shown on this Italian language blog: http://tarapippo.blogspot.mx/2010/02...s-sm-1071.html

I think there was a later model, called the SM-7071. Both used small CRT displays for presenting spectrum data and there wasn't a computer interface to extract this data.
