| The front
of the LP3000 sports the TI logo and the Deskmath nickname in a gold trim.
|
| The first version of the TI-3000
calculator with the Deskmath name and the odd LP3000 designation.
|
| The most obvious difference between
the Deskmath LP3000 (left) and the later TI-3000 (right) is the number of visible screws on the back of the calculators.
|
| Even the top
part of the housing gives some modifications for both cost reduction (missing inserts) and enhanced design (rounded edges).
|
| The printed circuit board
(PCB) of the Deskmath LP3000 looks different to the
later TI-3000. Please notice the Panaplex II display sporting only 8 digits but 3 signs.
