The TI-3100 Pocket Dialer introduced in 1989 realized a perfect enhancement of the earlier TI-2700 Mini Data Bank or the TI-2400 Phone Bank.
backside of the housing covers a loudspeaker compatible with the headset of an
old-fashioned phone. By simply choosing one of about 125 named stored in the
internal memory the associated number is given on the display. Simply by
pressing the yellow DIAL key the Pocket
Dialer converts the number digit by digit into the multitone sound used in the
multifrequency phones and emits them with the loudspeaker.
During dialing phone numbers most keys of the keyboard could be covered by a small lid. These keys access all remaing features of the Pocket Dialer like a 10-digit calculator, a clock with alarm-time and the Databank.
One year later the TI-3200 Pro Dialer raised the memory capacity from 2k Byte to a whooping 8k Byte.
Both the TI-3200 Pro Dialer and the TI-3200 Pocket Dialer were available only two or three years, Texas Instruments never introduced successors.
Texas Instruments launched in 1987 a very innovative product line with the TI-2400 Phone Bank, TI-2600 Personal Banker, TI-2700 Mini Data Bank, and TI-2800 Paperless Printer followed till 1990 with the TI-2100 Pocket Info, TI-2900 Info Bank, TI-3100 Pocket Dialer, TI-3200 Pro Dialer, and TI-3400 Europa.
If you know the history of Texas Instruments it seems to commemorate the introduction of the TI-2500 Datamath a quarter century ago.
