Motorola Digital Personal Communicator
In 1989, the Digital Personal Communicator, or DPC, was introduced as a
lower cost alternative to the 9800X. Light or dark gray in color, the
phone featured a green or orange 7-character segment LED display. It
closely resembled the 9800x in terms of the keypad design and background
and the main body. Early DPCs of the 9800X-era featured the elongated
antenna base, round-top side grips, and white-on-gray keypad.
Later
versions (most likely after 1991) lost the 9800X-specific physical
features, but kept the same basic form. Bone white models were also
available as special editions to cellular providers in the US. An
upscale version of the DPC, known as the
MicroTAC 950, or the
MicroTAC Alpha
in later years featured an 8-character green or orange dot-matrix LED
display and the return of the alpha-numeric phonebook.
The Alpha phones
were "upscale" in that they had more user-programmable options. Also,
Alpha phones featured the side grip arrow keys. Soon, an "affordable"
DPC 550 came to the market. Almost identical to the Digital Personal
Communicator, the
DPC 550 featured little with the most basic of operations.
