So you could hold a rotary phone up to your Mac
and dial numbers with HyperCard? ;-)
A little unit that was popular in the 1980's was
a small box about 1/2 the thickenss of a pager with
a speaker on the back and a keypad on the front.
They could store several phone numbers for autodialing
with DTMF on any phone. More expensive ones had
an LCD display and stored around 100 numbers.
They also worked for when you needed to use voice
mail or to remote control an answering machine over
a rotary or pulse tone only phone. Stripped down
versions often came with answering machines for
remote control, those were popular with hackers since
with a little work they could do the same things
as the more expensive DTMF dialers. :)
Just one of the neat gadgets killed off by the
digital PDAs and organizers.
