You'll get precise performance, too. No more than you need -- no less than you want. The CBI gives you a choice of an Intel Pentium III processor with blistering speeds or an Intel Celeron processor for solid performance at a reasonable cost -- whichever fits your needs.

Either way, Hi-Tec's dependable engineering and customer service make the CBI single board computer a long-term winner.

DRAM Memory:
The SDRAM interface consists of two dual in-line memory module (DIMM) sockets and supports auto detection of memory up to 512MB of Synchronous DRAM (SDRAM) memory. Minimum memory size is 8MB. The DIMM memory is PC-100 compliant for all speeds, which means that they comply with Intel's PC SDRAM specifications. Uses industry standard 64-bit (non-ECC) or 72-bit (ECC) wide gold finger DIMM DRAM in two 168-pin DIMM sockets.

Memory Hole:
Supports a 1MB memory hole option at 15-16MB.

Error Checking and Correction:
The memory interface supports ECC modes via BIOS setting for multiple-bit error detection and single-bit error correction.

PCI Local Bus Interface:
Fully compliant with the PCI Local Bus 2.1 Specification. This board has optimized the PCI interface to allow the processor to sustain the highest possible bandwidth (greater than 100MB/sec sustained) and supports PCI-to-PCI bridge technology.

Universal Serial Bus (USB):
Supports two USB 1.0 ports for serial transfers at 12 or 1.5Mbit/sec. The Universal Serial Bus is an interface allowing for connectivity to many standard PC peripherals via an external port.

System Hardware Monitor:
Provides monitoring of system voltages, temperature and fan speed.

Floppy Drive Interface:
Supports up to two floppy disk drives in combinations of 360K to 2.88MB.

AGP Super VGA Interface:
The 69000 video interface is an Accelerated Graphics Port (AGP) device with 2MB of on-chip memory. AGP is designed to off-load the PCI Bus by allowing graphics data to move directly from system memory. The interface supports pixel resolutions up to 1280 x 1024 non-interlaced. Software drivers are available for most popular operating systems.

Serial Interface:
Two high speed FIFO (16C550) serial ports with independently programmable baud rates. Each serial port has BIOS selectable addressing.

PCI 10/100Base-T Ethernet Interface:
The PCI Ethernet interface (Intel 82559) supports 10/100Base-T via an RJ-45 connector on the board's I/O bracket. The interface is compliant with IEEE 802.3 and PCI Local Bus 2.1 Specifications. Link status and activity LEDs are on the I/O bracket. Software drivers are available for most popular operating systems.

PCI Ultra Wide SCSI Interface:
The SCSI interface is a PCI Bus Master device using the Adaptec AIC-7880 chip. Supports Ultra Wide SCSI operation up to 40MB per second and bursts data to the host at full PCI speeds. Enable/disable active termination is provided with terminator voltage protected by self-resetting fuses. Software drivers are available for most popular operating systems.

PCI EIDE Ultra DMA/33 Interface (Dual):
Dual high performance PCI Bus Master EIDE interfaces are capable of supporting up to four IDE Type 4 disk drives in a master/slave configuration. Supports Ultra DMA/33 with synchronous DMA mode transfers up to 33MB per second.

Watchdog Timer:
The software controlled watchdog timer monitors system activity and generates a reset pulse in the event of a time-out.

Enhanced Bi-Directional Parallel Interface:
