Hardware Module Descriptions
Processor Board
Processor/Chip Set
The terminal uses an Intel architecture processor, which permits it to
leverage existing software drivers and applications, as well as provide
the greatest flexibility in choosing an operating system. This provides
several other advantages:
• Capable of SW MPEG-1 or MPEG-2 playback at 30 frames per
second with 22 kHz stereo audio (may be limited by OS
constraints).
• SoundBlaster
®
-compatible audio
• Expansion capabilities for optional features and future
requirements (ISA/PCI bus and USB)
Release 2.4
• Intel Pentium III 500 MHz or 700 MHz Processor, or Intel Celeron
550 MHz or 600 MHz Processor (µPGA package) used with the
Intel 440BX PC chipset. The 440BX chipset consists of the 82440BX
System Controller (North Bridge chip), also called the MTXC, and
the 82371AB (South Bridge chip), also called the PIIX4.
• A 100 MHz system bus
• 64 MB memory with ability to add SODIMMS to increase the
memory capacity of the terminal
Release 2.5
• Intel 700 MHz Celeron Processor or Intel 1 GHz Pentium III
Processor (BGA package) on board, removing the µPGA processor
socket. Intel 440BX chipset same as in Release 2.4
• 100 MHz system bus and memory support, 64-bit bus width, and
AGP video interface.
• 128 MB memory with ability to expand like Release 2.4.
