    Mine was a 300 baud Novation J-Cat in 1983, connected to my TRS-80 Model 
III. Direct connect, and I wrote a simple BASIC program to dial out by pulsing 
the hook relay.


    Dave, I have a Livermore 76B:


    From a 1979 issue of Datamation:

 	Bell 103/113A-compatible originate-only  type
 	Up to 450 bps using FSK modulation
 	Asynchronous,  half/full-duplex operation
 	Acoustic with  RS232B/C  interface
 	Features alternate voice-data
