Default AT&T Dataphone II Autocall 2224B

Back in the 1985-ish businesses that could afford it would purchase or lease a modem from the Telephone company. Back then your computers were typically IBM PC AT computers. This is the type of Data Modem that a business would have used with that computer. connected via the DB25 Serial adapter. This one is complete and its in working condition. Now I have to connect it via the DB25 Serial cable and see if I can find its DSU (Data Service Unit) manual....somewhere.

My initial upload of 6 photos didn't get in so I resized them to 800x600 and posted just front and back. - Enjoy.
