Subject: [GreenKeys] Model 28ASR and OKI relay switch assembly

 

Attached are some pictures of the TTY, sel-cal unit and the OKI assembly.

As far as I know the sel-cal unit is a mechanically selective, electrically activated switching unit that turns on the Teletype machine when it 'sees' a user-adjustable sequence of characters, such as an amateur radio call sign.

I've also attached some pictures of an old OKI relay switch bank that I am giving away to anyone who wants it.

The equipment is located on Long Island New York about 25 miles east of New York City.
