Processor Board

Processor/Chip Set

The terminal uses an Intel architecture proces s o r, which p e rmit s it to
leverage existing software drivers and applica t ion s , as well as provide
the greatest flexibility in choos ing an ope ra t in g sy stem. 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 futu re
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), als o called t h e MTXC , a n d
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 Pe n tium 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.
