> 1070 cycles is the idle tone from the tty or Mark
> 1270 cycles is the space tone when sending or rotary dialing

    Those are the standard tones used by Bell 103 modems for the originating 
station.  It's possible you could just plug it into the telephone jack of a 
notebook computer and talk to it, if you knew all the right settings.

    Search for "bell 103 modem" on Wikipedia for more.  Be prepared to waste 
the rest of the day -- the "Telecommunications History" link looks 
interesting :-)
