| The backside
of this rare PLT FHH1 Engineering Sample covers the
important label with its foldable stand.
|
| Removing the stand
gives some important
information: Model No: PLT - FHH1, © 2002, Made in Taiwan. Please notice the hidden slot for the memory card under the removed battery.
|
| Disassembling
the PLT FHH1 is pretty simple due to solid connectors and some screws. Please notice the additional PCB for an additional, serial memory card near the battery contacts.

| The internal
construction of this Graphing calculator is dominated by the huge
LCD screen.

The display module
makes use of five integrated display drivers for the rows resp.
columns. |
| The row and column drivers
of the PLT FHH1 were manufactured by Sharp, Japan.
