I lived in the Binghamton, New York, area for 32 years and knew
Ed Link through folks like Harvey Roehl and George Melnyk.  I did
work on the "C Sharpe Minor" organ in Ed's home.

The organ at the Roberson Museum is no longer playing.  The auditorium
was converted into a convention center, but the organ was still
playable.  Then the Binghamton chapter of the ATOS decided to install
an electronic relay.  They cut the cable and then ran out of money so
there it sits, waiting for funding.

The discussion about the vacuum unit used in the Link organ relay and
the aviation trainer was interesting as I have one of those units which
I obtained from Ed Link and it has run my homemade central vacuum
system for nearly 25 years, both in New York and also here in Colorado.
I proudly display it, but few people out here have ever heard of Link
and his trainer.
