TELEPHONE MODEM
A final option that you may wish to consider is
the Tl Telephone Coupler (about $200). A tele
phone modem allows your computer to com
municate with other computers using ordinary
telephone lines. A standard telephone headset
attaches to two rubber cups that are a part of
the Tl Telephone Coupler, and you then dial the
number of the computer that you wish to com
municate with. With the use of the Tl Telephone
Coupler, you can access public information net
works, such as The Source, CompuServe, Dow
Jones, and TEXNET. To use the Tl Telephone
Coupler, you must have an RS-232 Interface
Card or Adapter on your computer.
One of the better alternate values for your mod
em dollar can be found in the Signalman Mark III
modem (about $140) from Anchor Automation.
The battery-powered Signalman Mark III is a
direct-connect modem that can be used with
your TI-99/4A. It connects to the telephone with
the standard four-wire modular telephone jack
(found in most homes today).
Your computer's peripherals are its eyes and ears
to the world. The flexibility offered by your pe
ripherals will greatly increase the enjoyment and
usefulness you receive from your computer
system.
