i've visited a number of private telephone collections and Don's is absolutely massive by any standard. i can't do it justice, nor can any photo album. but he has, among other treasures, some highlights from my memory:
- autovon equipment
- several generations of digital switches
- electromechanical switches too
- loads and loads of paper documents on compact shelving
- bell labs prototypes
- phones that i never knew existed
- the first switch from Sprint's long distance network
i sincerely hope that he finds homes for all his collection.
