Additional Pictures
| The Equation Editor
of the PLT SHH1 looks familiar to us. Please notice the high resolution of the LCD screen.
|
Most Applications of the
Main Menu lead to simple screen simulations not accepting input data.
|
| The backside
of this rare Engineering Sample gives some important
information: Model No: PLT - SHH1, © 2002, Made in Taiwan, CPU: POMAP1509E.
|
|
| The cover of the PLT SHH1
with integrated Stylus holder.
|
The LI-ion battery
of the PLT SHH1 gives a list of related products.
|
| The internal
construction of this Graphing calculator is dominated by the huge
LCD screen.
|
|
| The display module
makes use of just two integrated display drivers for the rows resp.
columns. The IN-xxxxx part numbers may indicate Inventec as manufacturer of the Engineering Sample.
|
|
| Disassembling
the PLT SHH1 is pretty simple due to solid connectors and some screws. Please notice the pictogram for an additional, serial memory card near the battery contacts.

| The backside
of the Main-PCB (printed circuit board) with three
major Integrated Circuits: Hynix HY57V281620A: 8M * 16bits CMOS SDRAM Fujitsu 29LV400TC: 256k * 16bits CMOS FLASH-ROM Philips CA4885: unknown (probably power supply)
|
|
| The front-side
of the Main-PCB with the POMAP1509E dual-core processor of the Texas
Instruments OMAP™ family. It is supported by a Toshiba TC58V64A 8M * 8bits CMOS NAND EEPROM and some power supply components. The huge connector below the OMAP™ matches with a standard SD Memory Card.
