The
Datamath
Calculator
We learned
from Texas Instruments that they developed a family of next-generation Personal
Learning Tool products based on the LINUX operating system. The
The
PLT WS1 cradle features a wide range of connectivity:
• Wireless LAN operating in the 2.4GHz band (IEEE 802.11b) • • • • |
Disassembling
the PLT WS1 is a great exercise in reverse engineering! The internal
construction of the PLT WS1 is dominated by a total of 5 connectors and a slot
for the wireless LAN module operating in the 2.4GHz band. This module obviously
could be used in the larger, landscape oriented PET device labeled PLT FHH1 for Fido Hand
Held.
